CHAPTER 1 Introducing the ZyXEL Device

This chapter introduces the main applications and features of the ZyXEL Device.

1.1 Overview

This user's guide explains how to configure the following ZyXEL devices:

• The P-2302HW-P1 is a 4-port wireless router with Voice over IP (VoIP) communication capabilities that allow you to use a traditional analog telephone to make Internet calls. The P-2302HW-P1 is also a complete security solution with a robust firewall and content filtering.
• The P-2302HWL-P1 adds a Public Switched Telephone Network (PSTN) line feature which allows you to use your regular phone services and internet telephone services at the same time.

This user's guide refers to these models simply as the "ZyXEL Device". Please refer to Appendix A on page 279 for a complete list of features for your model.

1.1.1 VoIP Features

You can use the ZyXEL Device to make and receive VoIP telephone calls:

Figure 1 ZyXEL Device's VoIP Features

• Peer-to-Peer calls (A) - Use the ZyXEL Device to make a call to the recipient's IP address without using a SIP proxy server.
• Calls via a VoIP service provider (B) - The ZyXEL Device sends your call to a VoIP service provider's SIP server which forwards your calls to either VoIP or PSTN phones.

1.1.2 VoIP Trunking Gateway

VoIP trunking allows you to use your ZyXEL Device as a gateway between VoIP and PSTN networks.

Figure 2 ZyXEL Device as a VoIP Trunking Gateway

In this example, you use your analog phone (A) to call the ZyXEL Device (B). The ZyXEL Device changes the call into VoIP and sends it via the Internet to another VoIP phone(C).

1.1.3 ZyXEL Device's Router Features

Your ZyXEL Device provides shared Internet access through your existing Internet access gateway (company network, or your cable or DSL modem for example). Computers can connect to the ZyXEL Device's LAN ports (or wirelessly).

Figure 3 ZyXEL Device's Router Features

You can also configure firewall and content filtering on the ZyXEL Device for secure Internet access. When the firewall is on, all incoming traffic from the Internet to your network is blocked unless it is initiated from your network. This means that probes from the outside to your network are not allowed, but you can safely browse the Internet and download files.

Use content filtering to block access to specific web sites, with URL's containing keywords that you specify. You can define time periods and days during which content filtering is enabled and include or exclude particular computers on your network from content filtering. For example, you could block access to certain web sites for the kids.

Use bandwidth management to efficiently manage traffic on your network by giving priority to certain types of traffic and/or to particular computers. For example, you could make sure that the ZyXEL Device gives voice over Internet calls high priority, and/or limit bandwidth devoted to the boss's excessive file downloading.

1.2 LEDs (Lights)

The following graphic displays the labels of the LEDs.

CHAPTER 2 Introducing the Web Configurator

This chapter describes how to access the ZyXEL Device web configurator and provides an overview of its screens.

2.1 Web Configurator Overview

The web configurator is an HTML-based management interface that allows easy ZyXEL Device setup and management via Internet browser. Use Internet Explorer 6.0 and later or Netscape Navigator 7.0 and later versions. The recommended screen resolution is 1024 by 768 pixels.

In order to use the web configurator you need to allow:

• Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in Windows XP SP (Service Pack) 2.
• JavaScripts (enabled by default).
• Java permissions (enabled by default).

See the troubleshooting chapter if you want to make sure these functions are allowed in Internet Explorer or Netscape Navigator.

2.2 Accessing the Web Configurator

1 Make sure your ZyXEL Device hardware is properly connected and prepare your computer/computer network to connect to the ZyXEL Device (refer to the Quick Start Guide).
2 Launch your web browser.
3 Type "192.168.1.1" (the ZyXEL Device's default LAN IP address) as the URL. The Login screen appears.

Figure 5 Login Screen

4 Type "1234" (default) as the password, and click Login. In some versions, the default password appears automatically - if this is the case, click Login. The Change Password screen appears.

Figure 6 Change Password Screen

5 It is highly recommended to change your password. To change your password, type a new password, retype it to confirm it, and click Apply. Otherwise, click Ignore if you do not want to change your password right now. The Options screen should appear.

Figure 7 Select Mode Screen

6 In the Options screen,

• Click Go to Wizard setup if you are logging in for the first time or if you want to make basic changes. See Chapter 3 on page 47 for more information.
• Click Go to Advanced setup if you want to configure features that are not available in the wizards. The main screen appears. See Section 2.4 on page 42 for more information.
• Click Exit if you want to log out.

Note: For security reasons, the ZyXEL Device automatically logs you out if you do not use the web configurator for five minutes. If this happens, log in again.

2.3 Resetting the ZyXEL Device

Reset the ZyXEL Device in the following situations:

• You forgot your password.
• You cannot access the device using the web configurator. Check Troubleshooting in the Quick Start Guide to make sure you cannot access the device anymore.

If you reset the ZyXEL Device, you lose all of the changes you have made. The ZyXEL Device re-loads its default settings, and the password resets to "1234". You have to make all of your changes again.

Note: You will lose all of your changes when you push the RESET button.

To reset the ZyXEL Device,

1 Make sure the POWER LED is on and not blinking.

2 Press and hold the RESET button for ten seconds or until all the LEDs except for the WLAN begin to blink. Release the RESET button when the POWER LED begins to blink. The default settings have been restored.

If the ZyXEL Device restarts automatically, wait for the ZyXEL Device to finish restarting, and log in to the web configurator. The password is "1234". You have finished.

CHAPTER 5 Wireless LAN

This chapter discusses how to configure the wireless network settings in your ZyXEL Device.

5.1 Wireless Network Overview

The following figure provides an example of a wireless network.

Figure 38 Example of a Wireless Network

The wireless network is the part in the blue circle. In this wireless network, devices A and B use the access point (AP) to interact with the other devices (such as the printer) or with the Internet. Your ZyXEL Device is the AP.

Every wireless network must follow these basic guidelines.

• Every device in the same wireless network must use the same SSID.

The SSID is the name of the wireless network. It stands for Service Set IDentity.

• If two wireless networks overlap, they should use a different channel.

Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.

• Every device in the same wireless network must use security compatible with the AP.

Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.

5.2 Wireless Security Overview

The following sections introduce different types of wireless security you can set up in the wireless network.

5.2.1 SSD

Normally, the ZyXEL Device acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the ZyXEL Device does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.

This type of security is fairly weak, however, because there are ways for unauthorized wireless devices to get the SSID. In addition, unauthorized wireless devices can still see the information that is sent in the wireless network.

5.2.2 MAC Address Filter

Every device that can use a wireless network has a unique identification number, called a MAC address. A MAC address is usually written using twelve hexadecimal characters; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each device in the wireless network, see the device's User's Guide or other documentation.

You can use the MAC address filter to tell the ZyXEL Device which devices are allowed or not allowed to use the wireless network. If a device is allowed to use the wireless network, it still has to have the correct information (SSID, channel, and security). If a device is not allowed to use the wireless network, it does not matter if it has the correct information.

This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized wireless devices to get the MAC address of an authorized device. Then, they can use that MAC address to use the wireless network.

5.2.3 User Authentication

You can make every user log in to the wireless network before they can use it. This is called user authentication. However, every device in the wireless network has to support IEEE 802.1x to do this.

For wireless networks, user names and passwords for each user can be stored in a RADIUS server.

1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses.
2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.

Unauthorized wireless devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network.

5.2.4 Encryption

Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.

The types of encryption you can choose depend on the type of authentication. (See section 5.2.3 on page 86 for information about this.)

Table 32 Types of Encryption for Each Type of Authentication

Weakest Strongest	No Authentication	RADIUS Server
	None
	Static WEP
	WPA-PSK	WPA
	WPA2-PSK	WPA2

For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or WPA2-PSK.

Usually, you should set up the strongest encryption that every device in the wireless network supports. For example, suppose you have a wireless network with the ZyXEL Device. The ZyXEL Device does not have a local user database, and you do not have a RADIUS server. Therefore, there is no authentication. Suppose the wireless network has two devices. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network.

Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized wireless devices to figure out the original information pretty quickly.

When you select WPA2 or WPA2-PSK in your ZyXEL Device, you can also select an option (WPA compatible) to support WPA as well. In this case, if some of the devices support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPA compatible option in the ZyXEL Device.

Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every device in the wireless network must have the same key.

5.2.5 One-Touch Intelligent Security Technology (OTIST)

With ZyXEL's OTIST, you set up the SSID and the encryption (WEP or WPA-PSK) on the ZyXEL Device. Then, the ZyXEL Device transfers them to the devices in the wireless networks. As a result, you do not have to set up the SSID and encryption on every device in the wireless network.

The devices in the wireless network have to support OTIST, and they have to be in range of the ZyXEL Device when you activate it. See section 5.5 on page 95 for more details.

5.3 Additional Wireless Terms

The following table describes wireless network terms and acronyms used in the ZyXEL Device.

Table 33 Additional Wireless Terms

TERM	DESCRIPTION
RTS/CTS Threshold	In a wireless network which covers a large area, wireless devices are sometimes not aware of each other's presence. This may cause them to send information to the AP at the same time and result in information colliding and not getting through. By setting this value lower than the default value, the wireless devices must sometimes get permission to send information to the ZyXEL Device. The lower the value, the more often the devices must get permission. If this value is greater than the fragmentation threshold value (see below), then wireless devices never have to get permission to send information to the ZyXEL Device.
Authentication	The process of verifying whether a wireless device is allowed to use the wireless network.
Max. Frame Burst	Enable this to improve the performance of both pure IEEE 802.11g and mixed IEEE 802.11b/g networks. Maximum Frame Burst sets the maximum time that the ZyXEL Device transmits IEEE 802.11g wireless traffic only.
Fragmentation Threshold	A small fragmentation threshold is recommended for busy networks, while a larger threshold provides faster performance if the network is not very busy.

5.4 General WLAN Screen

Use this screen to enable the wireless network, assign the SSID and configure security settings on the ZyXEL Device. This screen changes depending on the security you select.

Note: If you are configuring the ZyXEL Device from a computer connected to the wireless LAN and you change the ZyXEL Device's SSID or WEP settings, you will lose your wireless connection when you press Apply to confirm.

CHAPTER 6

WAN

Use these screens to set up the ZyXEL Device on the WAN.

6.1 WAN Overview

You can configure the Internet connection, DNS servers, and how the ZyXEL Device sends routing information using RIP. In addition, you can set up a backup gateway in case the default gateway is not available.

6.1.1 PPPoE Encapsulation

The ZyXEL Device supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using PPPoE.

For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius).

One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals.

Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site.

By implementing PPPoE directly on the ZyXEL Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device does that part of the task. Furthermore, with NAT, all of the LANs' computers will have access.

6.1.2 WAN IP Address Assignment

Every computer on the Internet must have a unique IP address. If your networks are isolated from the Internet, for instance, only between your two branch offices, you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks.

Table 42 Private IP Address Ranges

10.0.0.0	-	10.255.255.255
172.16.0.0	-	172.31.255.255
192.168.0.0	-	192.168.255.255

You can obtain your IP address from the IANA, from an ISP or have it assigned by a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses.

Note: Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Intermets and RFC 1466, Guidelines for Management of IP Address Space.

6.1.3 MAC Address

Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is assigned at the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02.

The WAN MAC address section allows users to configure the WAN port's MAC address by either using the factory default or cloning your computer's MAC address. Choose Factory Default to select the factory assigned default MAC Address.

Otherwise, click Spoof this computer's MAC address - IP Address and enter the IP address of your computer. Once it is successfully configured, the address will be copied to the rom file (ZyNOS configuration file). It will not change unless you change the setting or upload a different ROM file. It is recommended that you clone the MAC address prior to hooking up the WAN Port.

6.1.4 RIP Setup

See Section 7.1.5 on page 115.

6.1.5 DNS Server Address Assignment

The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave this blank, the domain name obtained by DHCP from the ISP is used. While you must enter the host name (System Name) on each individual computer, the domain name can be assigned from the ZyXEL Device via DHCP.

Use DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it.

The ZyXEL Device can get the DNS server addresses in the following ways.

1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server fields in the SYSTEM General screen.
2 If the ISP did not give you DNS server information, leave the DNS Server fields in the SYSTEM General screen set to 0.0.0.0 for the ISP to dynamically assign the DNS server IP addresses.

CHAPTER 7

LAN

Use these screens to set up the ZyXEL Device on the LAN. You can configure its IP address and subnet mask, DHCP services, and other subnets. You can also control how the ZyXEL Device sends routing information using RIP, and you can enable and disable Any IP.

7.1 LAN Overview

A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is usually a computer network limited to the immediate area, such as the same building or floor of a building.

7.1.1 IP Address and Subnet Mask

Similar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number.

Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.

If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0 and you must enable the Network Address Translation (NAT) feature of the ZyXEL Device. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network.

Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your ZyXEL Device, but make sure that no other device on your network is using that IP address.

The subnet mask specifies the network number portion of an IP address. Your ZyXEL Device will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the ZyXEL Device unless you are instructed to do otherwise.

7.1.2 DHCP Setup

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the ZyXEL Device as a DHCP server or disable it. When configured as a server, the ZyXEL Device provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on your LAN, or else each computer must be manually configured.

The ZyXEL Device is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool). See the product specifications in the appendices. Do not assign static IP addresses from the DHCP pool to your LAN computers.

These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), read the embedded web configurator help regarding what fields need to be configured.

7.1.3 LAN TCP/IP

The ZyXEL Device has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability.

The LAN parameters of the ZyXEL Device are preset in the factory with the following values:

• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.

These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), read the embedded web configurator help regarding what fields need to be configured.

7.1.4 DNS Server Address

DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a machine before you can access it. The DNS server addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP address and subnet mask.

There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up. If your ISP gives you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup, otherwise, leave them blank.

Some ISPs choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the DNS servers are conveyed through IPCP negotiation. The ZyXEL Device supports the IPCP DNS server extensions through the DNS proxy feature.

If the Primary and Secondary DNS Server fields in the LAN Setup screen are not specified, for instance, left as 0.0.0.0, the ZyXEL Device tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS query to the ZyXEL Device, the ZyXEL Device forwards the query to the real DNS server learned through IPCP and relays the response back to the computer.

Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the LAN Setup screen. This way, the ZyXEL Device can pass the DNS servers to the computers and the computers can query the DNS server directly without the ZyXEL Device's intervention.

7.1.5 RIP Setup

RIP (Routing Information Protocol) allows a router to exchange routing information with other routers. The RIP Direction field controls the sending and receiving of RIP packets. When set to:

• Both - the ZyXEL Device will broadcast its routing table periodically and incorporate the RIP information that it receives.
• In Only - the ZyXEL Device will not send any RIP packets but will accept all RIP packets received.
• Out Only - the ZyXEL Device will send out RIP packets but will not accept any RIP packets received.
• None - the ZyXEL Device will not send any RIP packets and will ignore any RIP packets received.

The Version field controls the format and the broadcasting method of the RIP packets that the ZyXEL Device sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology.

Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.

7.1.6 Multicast

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1.

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed information about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address

224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts (including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers group.

The ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the ZyXEL Device queries all directly connected networks to gather group membership. After that, the ZyXEL Device periodically updates this information. IP multicasting can be enabled/disabled on the ZyXEL Device LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces.

7.1.7 Any IP

Traditionally, you must set the IP addresses and the subnet masks of a computer and the ZyXEL Device to be in the same subnet to allow the computer to access the Internet (through the ZyXEL Device). In cases where your computer is required to use a static IP address in another network, you may need to manually configure the network settings of the computer every time you want to access the Internet via the ZyXEL Device.

With the Any IP feature and NAT enabled, the ZyXEL Device allows a computer to access the Internet without changing the network settings (such as IP address and subnet mask) of the computer, when the IP addresses of the computer and the ZyXEL Device are not in the same subnet. Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply connect the computer to the ZyXEL Device and access the Internet.

The following figure depicts a scenario where a computer is set to use a static private IP address in the corporate environment. In a residential house where a ZyXEL Device is installed, you can still use the computer to access the Internet without changing the network settings, even when the IP addresses of the computer and the ZyXEL Device are not in the same subnet.

Figure 57 Any IP Example

The Any IP feature does not apply to a computer using either a dynamic IP address or a static IP address that is in the same subnet as the ZyXEL Device's IP address.

Note: You must enable NAT to use the Any IP feature on the ZyXEL Device.

Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address, also known as a Media Access Control or MAC address, on the local area network. IP routing table is defined on IP Ethernet devices (the ZyXEL Device) to decide which hop to use, to help forward data along to its specified destination.

The following lists out the steps taken, when a computer tries to access the Internet for the first time through the ZyXEL Device.

1 When a computer (which is in a different subnet) first attempts to access the Internet, it sends packets to its default gateway (which is not the ZyXEL Device) by looking at the MAC address in its ARP table.
2 When the computer cannot locate the default gateway, an ARP request is broadcast on the LAN.
3 The ZyXEL Device receives the ARP request and replies to the computer with its own MAC address.
4 The computer updates the MAC address for the default gateway to the ARP table. Once the ARP table is updated, the computer is able to access the Internet through the ZyXEL Device.
5 When the ZyXEL Device receives packets from the computer, it creates an entry in the IP routing table so it can properly forward packets intended for the computer.

After all the routing information is updated, the computer can access the ZyXEL Device and the Internet as if it is in the same subnet as the ZyXEL Device.

CHAPTER 8 NAT

This chapter discusses how to configure NAT on the ZyXEL Device.

8.1 NAT Overview

Use these screens to configure port forwarding and trigger ports for the ZyXEL Device. You can also enable and disable SIP, FTP, and H.323 ALG.

8.1.1 Port Forwarding: Services and Port Numbers

A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world.

Use the Network > NAT > Port Forwarding screen to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers.

In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded.

See Appendix F on page 323 for examples of services.

For example., let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet.

Figure 64 Multiple Servers Behind NAT Example

8.1.2 Trigger Port Forwarding

Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address,

Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The ZyXEL Device records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the ZyXEL Device's WAN port receives a response with a specific port number and protocol ("incoming" port), the ZyXEL Device forwards the traffic to the LAN IP address of the computer that sent the request. After that computer's connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application.

8.1.2.1 Trigger Port Forwarding Example

The following is an example of trigger port forwarding.

Figure 65 Trigger Port Forwarding Process: Example

1 Jane requests a file from the Real Audio server (port 7070).
2 Port 7070 is a "trigger" port and causes the ZyXEL Device to record Jane's computer IP address. The ZyXEL Device associates Jane's computer IP address with the "incoming" port range of 6970-7170.
3 The Real Audio server responds using a port number ranging between 6970-7170.
4 The ZyXEL Device forwards the traffic to Jane's computer IP address.
5 Only Jane can connect to the Real Audio server until the connection is closed or times out. The ZyXEL Device times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol).

8.1.2.2 Two Points To Remember About Trigger Ports

1 Trigger events only happen on data that is coming from inside the ZyXEL Device and going to the outside.
2 If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN can't trigger it.

8.1.3 SIP ALG

Some NAT routers may include a SIP Application Layer Gateway (ALG). A SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses embedded in the data stream. When the ZyXEL Device registers with the SIP register server, the SIP ALG translates the ZyXEL Device's private IP address inside the SIP data stream to a public IP address. You do not need to use STUN or an outbound proxy (see Chapter 9 on page 135) if your ZyXEL Device is behind a SIP ALG.

Max NAT/Firewall Session Per User	When computers use peer to peer applications, such as file sharing applications, they may use a large number of NAT sessions. If you do not limit the number of NAT sessions a single client can establish, this can result in all of the available NAT sessions being used. In this case, no additional NAT sessions can be established, and users may not be able to access the Internet. Each NAT session establishes a corresponding firewall session. Use this field to limit the number of NAT/firewall sessions each client computer can establish through the ZyXEL Device. If your network has a small number of clients using peer to peer applications, you can raise this number to ensure that their performance is not degraded by the number of NAT sessions they can establish. If your network has a large number of users using peer to peer applications, you can lower this number to ensure no single client is using all of the available NAT sessions.

CHAPTER 9 SIP

Use these screens to set up your SIP accounts and to configure QoS settings.

9.1 SIP Overview

9.1.1 Introduction to VoIP

VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This allows you to make phone calls and send faxes over the Internet at a fraction of the cost of using the traditional circuit-switched telephone network. You can also use servers to run telephone service applications like PBX services and voice mail. Internet Telephony Service Provider (ITSP) companies provide VoIP service. A company could alternatively set up an IP-PBX and provide it's own VoIP service.

Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to handle a telephone call. VoIP can use advanced voice coding techniques with compression to reduce the required bandwidth.

9.1.2 Introduction to SIP

The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet.

SIP signaling is separate from the media for which it handles sessions. The media that is exchanged during the session can use a different path from that of the signaling. SIP handles telephone calls and can interface with traditional circuit-switched telephone networks.

9.1.3 SIP Identities

A SIP account uses an identity (sometimes referred to as a SIP address). A complete SIP identity is called a SIP URI (Uniform Resource Identifier). A SIP account's URI identifies the SIP account in a way similar to the way an e-mail address identifies an e-mail account. The format of a SIP identity is SIP-Number@SIP-Service-Domain.

9.1.3.1 SIP Number

The SIP number is the part of the SIP URI that comes before the "@” symbol. A SIP number can use letters like in an e-mail address ([e-mail] for example) or numbers like a telephone number ([e-mail] for example).

9.1.3.2 SIP Service Domain

The SIP service domain of the VoIP service provider (the company that lets you make phone calls over the Internet) is the domain name in a SIP URI. For example, if the SIP address is [e-mail], then “VoIP-provider.com” is the SIP service domain.

9.1.4 SIP Call Progression

The following figure displays the basic steps in the setup and tear down of a SIP call. A calls B.

Table 59 SIP Call Progression

A		B
1. INVITE
		2. Ringing
		3. OK
4. ACK
	5. Dialogue (voice traffic)
6. BYE
		7. OK

A sends a SIP INVITE request to B. This message is an invitation for B to participate in a SIP telephone call.

3 B sends a response indicating that the telephone is ringing.
4 B sends an OK response after the call is answered.
5 A then sends an ACK message to acknowledge that B has answered the call.
6 Now A and B exchange voice media (talk).
7 After talking, A hangs up and sends a BYE request.
8 B replies with an OK response confirming receipt of the BYE request and the call is terminated.

9.1.5 SIP Client Server

SIP is a client-server protocol. A SIP client is an application program or device that sends SIP requests. A SIP server responds to the SIP requests.

When you use SIP to make a VoIP call, it originates at a client and terminates at a server. A SIP client could be a computer or a SIP phone. One device can act as both a SIP client and a SIP server.

9.1.5.1 SIP User Agent

A SIP user agent can make and receive VoIP telephone calls. This means that SIP can be used for peer-to-peer communications even though it is a client-server protocol. In the following figure, either A or B can act as a SIP user agent client to initiate a call. A and B can also both act as a SIP user agent to receive the call.

Figure 71 SIP User Agent

9.1.5.2 SIP Proxy Server

A SIP proxy server receives requests from clients and forwards them to another server.

In the following example, you want to use client device A to call someone who is using client device C.

1 The client device (A in the figure) sends a call invitation to the SIP proxy server (B).
2 The SIP proxy server forwards the call invitation to C.

Figure 72 SIP Proxy Server

9.1.5.3 SIP Redirect Server

A SIP redirect server accepts SIP requests, translates the destination address to an IP address and sends the translated IP address back to the device that sent the request. Then the client device that originally sent the request can send requests to the IP address that it received back from the redirect server. Redirect servers do not initiate SIP requests.

In the following example, you want to use client device A to call someone who is using client device C.

1 Client device A sends a call invitation for C to the SIP redirect server (B).
2 The SIP redirect server sends the invitation back to A with C's IP address (or domain name).
3 Client device A then sends the call invitation to client device C.

Figure 73 SIP Redirect Server

9.1.5.4 SIP Register Server

A SIP register server maintains a database of SIP identity-to-IP address (or domain name) mapping. The register server checks your user name and password when you register.

9.1.6 RTP

When you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is used to handle voice data transfer. See RFC 1889 for details on RTP.

9.1.7 NAT and SIP

The ZyXEL Device must register its public IP address with a SIP register server. If there is a NAT router between the ZyXEL Device and the SIP register server, the ZyXEL Device probably has a private IP address. The ZyXEL Device lists its IP address in the SIP message that it sends to the SIP register server. NAT does not translate this IP address in the SIP message. The SIP register server gets the ZyXEL Device's IP address from inside the SIP message and maps it to your SIP identity. If the ZyXEL Device has a private IP address listed in the SIP message, the SIP server cannot map it to your SIP identity. See Chapter 8 on page 127 for more information about NAT.

Use a SIP ALG (Application Layer Gateway), Use NAT, STUN, or outbound proxy to allow the ZyXEL Device to list its public IP address in the SIP messages.

9.1.7.1 SIP ALG

See Section 8.1.3 on page 129.

9.1.7.2 Use NAT

If you know the NAT router's public IP address and SIP port number, you can use the Use NAT feature to manually configure the ZyXEL Device to use a them in the SIP messages. This eliminates the need for STUN or a SIP ALG.

You must also configure the NAT router to forward traffic with this port number to the ZyXEL Device.

9.1.7.3 STUN

STUN (Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators) allows the ZyXEL Device to find the presence and types of NAT routers and/or firewalls between it and the public Internet. STUN also allows the ZyXEL Device to find the public IP address that NAT assigned, so the ZyXEL Device can embed it in the SIP data stream. STUN does not work with symmetric NAT routers or firewalls. See RFC 3489 for details on STUN.

The following figure shows how STUN works.

1 The ZyXEL Device (A) sends SIP packets to the STUN server (B).
2 The STUN server (B) finds the public IP address and port number that the NAT router used on the ZyXEL Device's SIP packets and sends them to the ZyXEL Device.
3 The ZyXEL Device uses the public IP address and port number in the SIP packets that it sends to the SIP server (C).

Figure 74 STUN

9.1.7.4 Outbound Proxy

Your VoIP service provider may host a SIP outbound proxy server to handle all of the ZyXEL Device's VoIP traffic. This allows the ZyXEL Device to work with any type of NAT router and eliminates the need for STUN or a SIP ALG. Turn off a SIP ALG on a NAT router in front of the ZyXEL Device to keep it from retranslating the IP address (since this is already handled by the outbound proxy server).

9.1.8 Voice Coding

A codec (coder/decoder) codes analog voice signals into digital signals and decodes the digital signals back into voice signals. The ZyXEL Device supports the following codecs.

• G.711 is a Pulse Code Modulation (PCM) waveform codec. PCM measures analog signal amplitudes at regular time intervals and converts them into bits. G.711 provides very good sound quality but requires 64kbps of bandwidth.
• G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec that uses a filter based on information about how the human vocal tract produces sounds. G.729 provides good sound quality and reduces the required bandwidth to 8kbps.

9.1.9 PSTN Call Setup Signaling

PSTNs (Public Switched Telephone Networks) use DTMF or pulse dialing to set up telephone calls.

Dual-Tone Multi-Frequency (DTMF) signaling uses pairs of frequencies (one lower frequency and one higher frequency) to set up calls. It is also known as Touch Tone®. Each of the keys on a DTMF telephone corresponds to a different pair of frequencies.

Pulse dialing sends a series of clicks to the local phone office in order to dial numbers.

9.1.10 MWI (Message Waiting Indication)

Enable Message Waiting Indication (MWI) enables your phone to give you a message—waiting (beeping) dial tone when you have one or more voice messages. Your VoIP service provider must have a messaging system that sends message-waiting-status SIP packets as defined in RFC 3842.

9.1.11 Quality of Service (QoS)

Quality of Service (QoS) refers to both a network's ability to deliver data with minimum delay and the networking methods used to provide bandwidth for real-time multimedia applications.

9.1.11.1 Type of Service (ToS)

Network traffic can be classified by setting the ToS (Type Of Service) values at the data source (for example, at the ZyXEL Device) so a server can decide the best method of delivery, that is the least cost, fastest route and so on.

9.1.11.2 DiffServ

DiffServ is a class of service (CoS) model that marks packets so that they receive specific per-hop treatment at DiffServ-compliant network devices along the route based on the application types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the level of service desired. This allows the intermediary DiffServ-compliant network devices to handle the packets differently depending on the code points without the need to negotiate paths or remember state information for every flow. In addition, applications do not have to request a particular service or give advanced notice of where the traffic is going.¹

9.1.11.3 DSCP and Per-Hop Behavior

DiffServ defines a new DS (Differentiated Services) field to replace the Type of Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define up to 64 service levels. The following figure illustrates the DS field.

Figure 75 DiffServ: Differentiated Service Field

DSCP (6-bit)

Unused (2-bit)

DSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ compliant, ToS-enabled network device will not conflict with the DSCP mapping.

The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be marked for different priorities of forwarding. Resources can then be allocated according to the DSCP values and the configured policies.

9.1.11.4 VLAN

Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical networks. Only stations within the same group can communicate with each other.

Your ZyXEL Device can add IEEE 802.1Q VLAN ID tags to voice frames that it sends to the network. This allows the ZyXEL Device to communicate with a SIP server that is a member of the same VLAN group. Some ISPs use the VLAN tag to identify voice traffic and give it priority over other traffic.

9.2 SIP Screens

9.2.1 SIP Settings Screen

SIP Account	This field displays the SIP account you see in this screen.
SIP Server Settings
URL Type	Select whether or not to include the SIP service domain name when the ZyXEL Device sends the SIP number.SIP - include the SIP service domain nameTEL - do not include the SIP service domain name
Expiration Duration	Enter the number of seconds your SIP account is registered with the SIP register server before it is deleted. The ZyXEL Device automatically tries to re-register your SIP account when one-half of this time has passed. (The SIP register server might have a different expiration.)
Register Re-send timer	Enter the number of seconds the ZyXEL Device waits before it tries again to register the SIP account, if the first try failed or if there is no response.
Session Expires	Enter the number of seconds the conversation can last before the call is automatically disconnected. Usually, when one-half of this time has passed, the ZyXEL Device or the other party updates this timer to prevent this from happening.
Min-SE	Enter the minimum number of seconds the ZyXEL Device accepts for a session expiration time when it receives a request to start a SIP session. If the request has a shorter time, the ZyXEL Device rejects it.
RTP Port Range
Start Port End Port	Enter the listening port number(s) for RTP traffic, if your VoIP service provider gave you this information. Otherwise, keep the default values.To enter one port number, enter the port number in the Start Port and End Port fields.To enter a range of ports, • enter the port number at the beginning of the range in the Start Port field • enter the port number at the end of the range in the End Port field.
Voice Compression	Select the type of voice coder/decoder (codec) that you want the ZyXEL Device to use. G.711 provides higher voice quality but requires more bandwidth (64 kbps).• G.711A is typically used in Europe.• G.711u is typically used in North America and Japan.In contrast, G.729 only requires 8 kbps.The ZyXEL Device must use the same codec as the peer. When two SIP devices start a SIP session, they must agree on a codec.Note: In order to use the VoIP trunking feature you must set the Primary Compression Type to G.729.
Primary Compression Type	Select the ZyXEL Device's first choice for voice coder/decoder.
Secondary Compression Type	Select the ZyXEL Device's second choice for voice coder/decoder. Select None if you only want the ZyXEL Device to accept the first choice.
Third Compression Type	This field is disabled if Secondary Compression Type is None.Select the ZyXEL Device's third choice for voice coder/decoder. Select None if you only want the ZyXEL Device to accept the first or second choice.

Table 61 VoIP > SIP > SIP Settings > Advanced

LABEL	DESCRIPTION

Server Port	Enter the port number that your SIP sessions use with the public IP address of the NAT router.
Outbound Proxy
Active	Select this if your VoIP service provider has a SIP outbound server to handle voice calls. This allows the ZyXEL Device to work with any type of NAT router and eliminates the need for STUN or a SIP ALG. Turn off any SIP ALG on a NAT router in front of the ZyXEL Device to keep it from retranslating the IP address (since this is already handled by the outbound proxy server).
Server Address	Enter the IP address or domain name of the SIP outbound proxy server.
Server Port	Enter the SIP outbound proxy server's listening port, if your VoIP service provider gave you one. Otherwise, keep the default value.
NAT Keep Alive
Active	Select this to stop NAT routers between the ZyXEL Device and SIP server (a SIP proxy server or outbound proxy server) from dropping the SIP session. The ZyXEL Device does this by sending SIP notify messages to the SIP server based on the specified interval.

CHAPTER 10 Phone

Use these screens to configure the phones you use to make phone calls.

10.1 Phone Overview

You can configure the volume, echo cancellation and VAD settings for each individual phone port on the ZyXEL Device. You can also select which SIP account to use for making outgoing calls.

10.1.1 Voice Activity Detection/Silence Suppression/Comfort Noise

Voice Activity Detection (VAD) detects whether or not speech is present. This lets the ZyXEL Device reduce the bandwidth that a call uses by not transmitting "silent packets" when you are not speaking.

When using VAD, the ZyXEL Device generates comfort noise when the other party is not speaking. The comfort noise lets you know that the line is still connected as total silence could easily be mistaken for a lost connection.

10.1.2 Echo Cancellation

G.168 is an ITU-T standard for eliminating the echo caused by the sound of your voice reverberating in the telephone receiver while you talk.

10.1.3 Supplementary Phone Services Overview

Supplementary services such as call hold, call waiting, call transfer and so on, are generally available from your VoIP service provider. The ZyXEL Device supports the following services:

Call Hold
Call Waiting
Making a Second Call
Call Transfer
- Call Forwarding
Three-Way Conference
- Internal Calls

Note: To take full advantage of the supplementary phone services available through the ZyXEL Device's phone ports, you may need to subscribe to the services from your VoIP service provider.

10.1.3.1 The Flash Key

Flashing means to press the hook for a short period of time (a few hundred milliseconds) before releasing it. On newer telephones, there should be a "flash" key (button) that generates the signal electronically. If the flash key is not available, you can tap (press and immediately release) the hook by hand to achieve the same effect. However, using the flash key is preferred since the timing is much more precise. The ZyXEL Device may interpret manual tapping as hanging up if the duration is too long

You can invoke all the supplementary services by using the flash key.

10.1.3.2 Europe Type Supplementary Phone Services

This section describes how to use supplementary phone services with the Europe Type Call Service Mode. Commands for supplementary services are listed in the table below.

11.1 Phone Book Overview

Speed dial provides shortcuts for dialing frequently used (VoIP) phone numbers. It is also required if you want to make peer-to-peer calls. In peer-to-peer calls, you call another VoIP device directly without going through a SIP server. In the ZyXEL Device, you must set up a speed dial entry in the phone book in order to do this. Select Non-Proxy (Use IP or URL) in the Type column and enter the callee's IP address or domain name. The ZyXEL Device sends SIP INVITE requests to the peer VoIP device when you use the speed dial entry.

You do not need to configure a SIP account in order to make a peer-to-peer VoIP call.

CHAPTER 12 PSTN Line

This chapter applies to P-2302HWL-P1 models only. Use this screen to set up the PSTN line used to make regular phone calls. These phone calls do not use the Internet.

12.1 PSTN Line Overview

With the Public Switched Telephone Network (PSTN) line, you can make and receive regular phone calls. Use a prefix number to make a regular call. When the ZyXEL Device does not have power, you can make regular calls without dialing a prefix number.

You can also specify phone numbers that should always use the regular phone service (without having to dial a prefix number). Do this for emergency numbers (like those for contacting police, fire or emergency medical services).

Note: When the ZyXEL Device does not have power, only the phone connected to the PHONE 1 port can be used for making calls. Ensure you know which phone this is, so that in case of emergency you can make outgoing calls.

12.2 PSTN Line General Screen

Use this screen to set up the PSTN line you use to make regular phone calls. To access this screen, click VoIP > PSTN Line > General.

These numbers tell the ZyXEL Device that you want to make a regular phone call. It is not recommended to use the # key, however, because it is also used in Immediate Dial. (See VoIP > Phone > Common.)
Relay to PSTN Line	Enter phone numbers (for regular calls, not VoIP calls) that you want to dial without the prefix number. For example, you should enter emergency numbers. The number (1 - 9) is not a speed-dial number. It is just a sequential value that is not associated with any phone number.

CHAPTER 13 Volp Trunking

Use these screens to configure VoIP trunking on your ZyXEL Device.

13.1 VoIP Trunking Overview

VoIP trunking connects an IP network (like the Internet) and the Public Switched Telephone Network (PSTN). PSTN includes the world's circuit-switched telephone network which is composed of fixed and mobile telephones. VoIP trunking allows you to create VoIP links which PSTN (Public Switched Telephone Network) callers can use to:

• Make phone calls via the Internet - Make a PSTN call to the ZyXEL Device and it forwards the call to any SIP based VoIP phone.
• Save on long distance calls - The ZyXEL Device creates a VoIP link which can be used to connect to a PSTN phone in another country, province, region and so on.

Similarly, VoIP callers can:

• Make calls to PSTN subscribers at reduced cost - Connect to the ZyXEL Device via VoIP and the ZyXEL Device forwards the call to a PSTN phone.

Creating a link over the IP network requires two VoIP devices. VoIP trunking scenarios vary depending on how the VoIP devices work together and how they receive or forward PSTN calls. The following sections describe the details of VoIP trunking.

13.2 VoIP Trunking and Security

Your ZyXEL Device provides two types of authentication to prevent unauthorized callers from using it for VoIP trunking.

13.2.1 Auto Attendant and Authentication

Auto attendant is the ZyXEL Device's name for a service which controls settings specific to VoIP trunking. Most importantly it controls authentication for VoIP trunking. Auto attendant authentication is similar to using a calling card with a PIN (Personal Identification Number). Your ZyXEL Device can be configured so that it prompts callers to enter a PIN (via the phone pad) in order to process any call forwarding requests.

Other settings controlled by the auto attendant include a time limit to decide whether you want to forward a call from the ZyXEL Device or call the phone directly connected to the ZyXEL Device. When you call into your ZyXEL Device you can request to forward a call to another phone number simply by dialing that number. If you don't dial any number within a specified time limit (for example 5 seconds) then the phone directly connected to the ZyXEL Device rings. It also controls the time limit you have between dialing digits of a phone number.

13.2.2 Peer Call Authentication

VoIP devices can make peer calls to each other by using the IP address instead of a SIP number to establish a call. The advantage of this is that you do not need to pay a VoIP service provider. VoIP devices that connect using an IP address are referred to here as peer devices. A local peer device is where the VoIP call originates and a remote peer device is where the VoIP call ends. In the following figure, local peer device (A) connects to a remote peer device (B) via the IP address of B.

Figure 86 Peer Devices Connecting

A peer-to-peer call doesn't require any authentication, however, authentication is required when you request the remote peer device to forward a call. The remote peer device has a list of accounts, each consisting of a username and password, which are allowed to use the remote peer device to forward calls. These accounts make up an incoming authentication list.

The local peer device has a corresponding list of outgoing authentication accounts. These accounts consist of the IP address of a remote peer device, the port number to communicate over as well as a username and password to use for authentication. An outgoing authentication account must match an incoming authentication account's username and password in order for the remote device to forward calls. The following table shows example entries for incoming and outgoing authentication. The bolded entries must match in order for authentication between two peer devices to occur.

13.3 Call Rules

Call rules automate the forwarding of calls, first to a remote peer device and then to PSTN phones. This is used when you make frequent calls to several PSTN numbers in the same geographic area that start with the same numbers (for example an area code). If there is a remote peer device in that area, you can set up a VoIP link to it and have it forward the calls to PSTN phones. This works by configuring a pattern that the ZyXEL Device can recognize. A pattern is just the initial string of digits shared by the phone numbers. The following table shows the relationship between the phone numbers you want to call, the pattern you want to configure and the rule you want to set up.

Table 73 Call Rules

FREQUENTLY CALLED PSTN NUMBERS	PATTERN	CALL RULE
1-555-555-4321	1555	Set up a peer call to a remote peer device to forward calls starting with the numbers 1555.
1-555-544-5678
1-555-432-8888
1-111-555-4321	1111	Set up a peer call to a remote peer device to forward calls starting with the numbers 1111.
1-111-544-5678
1-111-432-8888

13.4 VoIP Trunking Scenarios

There are several different VoIP trunking scenarios.

13.4.1 VoIP Phone To PSTN Phone

A VoIP phone A makes a call to the ZyXEL Device B via VoIP. B forwards the call to a PSTN phone C. A can be an analog phone connected to the ZyXEL Device or any other phone capable of making calls over the IP network.

Figure 87 VoIP Phone To PSTN Phone

13.4.2 PSTN Phone To VoIP Phone

A PSTN phone A makes a call to the ZyXEL Device B. B connects A to a VoIP phone C over the IP network.

Figure 88 PSTN Phone To VoIP Phone

13.4.3 PSTN Phone To PSTN Phone via VoIP

A PSTN phone A makes a call to the ZyXEL Device B. B connects to a peer device C and C forwards the call to a PSTN phone D.

13.8 VoIP Trunking Example: VoIP to PSTN

This example shows how to configure VoIP to PSTN trunking to save on long distance calls.

13.8.1 Background Information

A company has its headquarters in city A and a branch office in city B. The headquarters often needs to call salespeople employed at the branch office. The sales employees often work away from the office and have PSTN phones (mobile or land based). The two offices have VoIP trunking devices and want to use VoIP trunking to save on calls from the headquarters to their sales team. The head office has a public IP address a.b.c.d and the branch office has a public IP address w.x.y.z.

Figure 93 VoIP to PSTN Example

The proposed solution is to establish a peer-to-peer call between the two ZyXEL Devices and have the branch office ZyXEL Device forward calls to the sales team members via PSTN.

13.8.2 Configuration Details: Outgoing

The ZyXEL Device (at headquarters) from which the call originates needs to have the following configuration settings:

1 Speed dial entries need to be set up for the numbers headquarters wants to call. The destination field of these entries is the IP address of the branch office ZyXEL Device. This must be a non-proxy IP address. The numbers are the phone numbers of the sales team members. This can be configured in the VoIP > Phone Book > Speed Dial screen.

Figure 94 VoIP to PSTN Example - Speed Dial Screen

2 An outgoing authentication account needs to be configured. This account consists of the IP address and port number of the branch office ZyXEL Device as well as the username and password for authentication. This username and password must match the incoming authentication account username and password on the branch office ZyXEL Device. The name of this rule is "CityB" referring to the branch office ZyXEL Device. In this example the username is "headquarters" and the password is "password". This can be configured in the VoIP > Trunking > Peer Call screen.

Figure 95 VoIP to PSTN Example - Outgoing Authentication

13.8.3 Configuration Details: Incoming

The branch office ZyXEL Device needs to have an incoming authentication account configured. This consists of a username and password. This account must match the username and password of the outgoing authentication account of the headquarters' ZyXEL Device. This can be configured in the VoIP > Trunking > Peer Call screen.

Figure 96 VoIP to PSTN Example - Incoming Authentication

13.8.4 Call Progression

The advantage of this kind of VoIP trunking is that once all the configuration is completed, the caller just has to dial a speed dial entry from a phone connected to their ZyXEL Device and the peer devices take care of the rest. This is what happens when headquarters wants to call their Sales1 employee, which is the first entry in the speed dial screen.

Table 77 VoIP Trunking Call Progression

HEADQUARTERS	BRANCH OFFICE	SALES1
A person at A dials #01 from the phone connected to the ZyXEL Device.
The ZyXEL Device at A inspects the number and connects to the remote peer device at B.
The remote peer device inspects the number and requests authentication in order to forward the call.
The ZyXEL Device at A sends outgoing authentication to the remote peer device.
The remote peer device confirms that the username and password match an account in its incoming authentication list.
	The remote peer device forwards the call to Sales1.
Sales1 picks up and the call commences.

13.9 VoIP Trunking Example: PSTN to PSTN via VoIP

This example shows how to configure a PSTN to PSTN call with a VoIP link. It also shows how call rules can be used to automate VoIP trunking.

13.9.1 Background Information

A company has its headquarters in two different cities. The sales manager (A) from headquarters often needs to call salespeople (D) employed at the branch office. The sales manager often works away from the headquarters office and the sales employees often work away from the branch office. The sales manager and the sales employees have PSTN phones (mobile or land based). The two offices have VoIP trunking devices. The sales manager wants to use VoIP trunking to save on calls to his sales team. The head office has a ZyXEL Device (B) with a PSTN line (tel: [phone]) connected to it. The branch office has a ZyXEL Device (C) with a public IP address w.x.y.z. The sales employee (D) has a PSTN phone with the number 555-555-4321.

Figure 97 PSTN to PSTN Example

The proposed solution is to configure a call rule which will allow the sales manager to call into the headquarters via PSTN, establish a VoIP link between the two ZyXEL Devices and have the remote peer device forward calls to the sales employees via PSTN.

13.9.2 Configuration Details: Outgoing

The ZyXEL Device (at headquarters) from which the VoIP link originates needs to have the following configuration settings:

1 Auto attendant authentication needs to be enabled for PSTN calls coming into the headquarters' ZyXEL Device. This ensures that no unauthorized callers use VoIP trunking. In this example the PIN (Personal Identification Number) is set to 12345. The settings dealing with dialing interval and a timeout period are left at default. The ZyXEL Device waits 10 seconds (after initial connection between PSTN caller and the ZyXEL Device) for the PSTN caller to initiate VoIP trunking by dialing another number. It waits 3 seconds between dialing digits before it determines that the entire phone number is entered. These settings can be configured in the VoIP > Trunking > General screen.

Figure 98 PSTN to PSTN Example: General Configuration

2 An outgoing authentication account needs to be configured. This account consists of the IP address and port number of the branch office ZyXEL Device as well as the username and password for authentication. This username and password must match the incoming authentication account username and password on the branch office ZyXEL Device. The name of this account is "CityB" referring to the branch office ZyXEL Device. In this example the username is "headquarters" and the password is "password". This can be configured in the VoIP > Trunking > Peer Call screen.

Figure 99 PSTN to PSTN Example - Outgoing Authentication

3 A call rule needs to be created. This rule tells the ZyXEL Device which remote peer device it should connect to in order to complete the call. This rule is composed of a pattern and an account name. This pattern is simply the first several digits of the number you want the remote device to connect to. In this example this is the first 4 digits (5555) of Sales1 telephone number. The account name is the name of the outgoing authentication account created in the Speed Dial screen (CityB). This setting can be configured in the VoIP > Trunking > Call Rule screen.

Figure 100 PSTN to PSTN Example - Call Rule

13.9.3 Configuration Details: Incoming

The branch office ZyXEL Device needs to have an incoming authentication account configured. This consists of a username and password. This account must match the username and password of the outgoing authentication account of the headquarters' ZyXEL Device. This can be configured in the VoIP > Trunking > Peer Call screen.

Figure 101 PSTN to PSTN Example - Incoming Authentication

13.9.4 Call Progression

The call is initiated by the manager dialing into the headquarter's ZyXEL Device via PSTN. In this scenario a VoIP link is established between headquarters and the branch office and then the call is forwarded to Sales1 using PSTN.

Table 78 PSTN to PSTN: VoIP Trunking Call Progression

MANAGER	HEADQUARTERS	BRANCH OFFICE	SALES1
The manager dials the PSTN number of the headquarters' ZyXEL Device. (222-222-2222)
The ZyXEL Device receives the call and sends a ringback alert tone to indicate to the caller that VoIP trunking is enabled.
The manager dials the PSTN number of Sales1 (555-555-1234).
The ZyXEL Device prompts the manager to enter the PIN in order to allow VoIP trunking.
The manager dials the PIN (12345).
	The ZyXEL Device confirms the password and allows for VoIP trunking. The ZyXEL Device inspects the phone number against call rules. Since the number starts with the pattern (5555), it uses the account (CityB) associated with this pattern to connect the call to the remote peer device at the branch office.
	The remote peer device inspects the number and requests authentication in order to forward the call.
	The ZyXEL Device at A sends outgoing authentication to the remote peer device.
	The remote peer device confirms that the username and password match an account in its incoming authentication list.
		The remote peer device forwards the call to Sales1.
Sales1 picks up and the call commences.

CHAPTER 14

Firewall

Use these screens to enable, configure and disable the firewall that protects your ZyXEL Device and your LAN from unwanted or malicious traffic.

14.1 Firewall Overview

The networking term "firewall" is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from an untrusted network. Of course, firewalls cannot solve every security problem. A firewall is one of the mechanisms used to establish a network security perimeter in support of a network security policy. It should never be the only mechanism or method employed. For a firewall to guard effectively, you must design and deploy it appropriately. This requires integrating the firewall into a broad information-security policy. In addition, specific policies must be implemented within the firewall itself.

14.1.1 Stateful Inspection Firewall

Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency; however, they may lack the granular application level access control or caching that some proxies support. Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises.

14.1.2 About the ZyXEL Device Firewall

The ZyXEL Device firewall is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated. The ZyXEL Device's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The ZyXEL Device can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network.

The ZyXEL Device is installed between the LAN and a broadband modem connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.

The ZyXEL Device has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas. The WAN (Wide Area Network) port attaches to the broadband (cable or DSL) modem to the Internet.

The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service.

14.1.3 Guidelines For Enhancing Security With Your Firewall

1 Change the default password via web configurator.
2 Think about access control before you connect to the network in any way, including attaching a modem to the port.
3 Limit who can access your router.
4 Don't enable any local service (such as telnet or FTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network.
5 For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces.
6 Protect against IP spoofing by making sure the firewall is active.
7 Keep the firewall in a secured (locked) room.

14.1.4 The Firewall, NAT and Remote Management

Figure 102 Firewall Rule Directions

14.1.4.1 LAN-to-WAN rules

LAN-to-WAN rules are local network to Internet firewall rules. The default is to forward all traffic from your local network to the Internet.

You can block certain LAN-to-WAN traffic in the Services screen (click the Services tab). All services displayed in the Blocked Services list box are LAN-to-WAN firewall rules that block those services originating from the LAN.

Blocked LAN-to-WAN packets are considered alerts. Alerts are "higher priority logs" that include system errors, attacks and attempted access to blocked web sites. Alerts appear in red in the View Log screen. You may choose to have alerts e-mailed immediately in the Log Settings screen.

LAN-to-LAN/ZyXEL Device means the LAN to the ZyXEL Device LAN interface. This is always allowed, as this is how you manage the ZyXEL Device from your local computer.

14.1.4.2 WAN-to-LAN rules

WAN-to-LAN rules are Internet to your local network firewall rules. The default is to block all traffic from the Internet to your local network.

How can you forward certain WAN to LAN traffic? You may allow traffic originating from the WAN to be forwarded to the LAN by:

• Configuring NAT port forwarding rules.
• Configuring WAN or LAN & WAN access for services in the Remote Management screens. When you allow remote management from the WAN, you are actually configuring WAN-to-WAN/ZyXEL Device firewall rules. WAN-to-WAN/ZyXEL Device firewall rules are Internet to the ZyXEL Device WAN interface firewall rules. The default is to block all such traffic. When you decide what WAN-to-LAN packets to log, you are in fact deciding what WAN-to-LAN and WAN-to-WAN/ZyXEL Device packets to log.

Forwarded WAN-to-LAN packets are not considered alerts.

14.2 Triangle Route

When the firewall is on, your ZyXEL Device acts as a secure gateway between your LAN and the Internet. In an ideal network topology, all incoming and outgoing network traffic passes through the ZyXEL Device to protect your LAN against attacks.

Figure 103 Ideal Firewall Setup

14.2.1 The "Triangle Route" Problem

A traffic route is a path for sending or receiving data packets between two Ethernet devices. You may have more than one connection to the Internet (through one or more ISPs). If an alternate gateway is on the LAN (and its IP address is in the same subnet as the ZyXEL Device's LAN IP address), the "triangle route" (also called asymmetrical route) problem may occur. The steps below describe the "triangle route" problem.

1 A computer on the LAN initiates a connection by sending out a SYN packet to a receiving server on the WAN.
2 The ZyXEL Device reroutes the SYN packet through Gateway A on the LAN to the WAN.
3 The reply from the WAN goes directly to the computer on the LAN without going through the ZyXEL Device.

As a result, the ZyXEL Device resets the connection, as the connection has not been acknowledged.

Figure 104 "Triangle Route" Problem

14.2.2 Solving the "Triangle Route" Problem

If you have the ZyXEL Device allow triangle route sessions, traffic from the WAN can go directly to a LAN computer without passing through the ZyXEL Device and its firewall protection.

Another solution is to use IP alias. IP alias allows you to partition your network into logical sections over the same Ethernet interface. Your ZyXEL Device supports up to three logical LAN interfaces with the ZyXEL Device being the gateway for each logical network.

It's like having multiple LAN networks that actually use the same physical cables and ports. By putting your LAN and Gateway A in different subnets, all returning network traffic must pass through the ZyXEL Device to your LAN. The following steps describe such a scenario.

1 A computer on the LAN initiates a connection by sending a SYN packet to a receiving server on the WAN.
2 The ZyXEL Device reroutes the packet to Gateway A, which is in Subnet 2.

3 The reply from the WAN goes to the ZyXEL Device.
4 The ZyXEL Device then sends it to the computer on the LAN in Subnet 1.

CHAPTER 15 Content Filter

Use these screens to create and enforce policies that restrict access to the Internet based on content.

15.1 Content Filtering Overview

Internet content filtering allows you to create and enforce Internet access policies tailored to their needs. Content filtering is the ability to block certain web features or websites with specific URL keywords.

The ZyXEL Device can block web features such as ActiveX controls, Java applets, cookies and disable web proxies. The ZyXEL Device also allows you to define time periods and days during which the ZyXEL Device performs content filtering.

CHAPTER 16 Static Route

Use these screens to configure static routes in the ZyXEL Device.

16.1 Static Route Overview

Each remote node specifies only the network to which the gateway is directly connected, and the ZyXEL Device has no knowledge of the networks beyond. For instance, the ZyXEL Device knows about network N2 in the following figure through remote node Router 1. However, the ZyXEL Device is unable to route a packet to network N3 because it doesn't know that there is a route through the same remote node Router 1 (via gateway Router 2). The static routes are for you to tell the ZyXEL Device about the networks beyond the remote nodes.

CHAPTER 17 Bandwidth MGMT

Use these screens to manage the amount of traffic the ZyXEL Device routes through each interface.

17.1 Bandwidth Management Overview

Bandwidth management allows you to allocate an interface's outgoing capacity to specific types of traffic. It can also help you make sure that the ZyXEL Device forwards certain types of traffic (especially real-time applications) with minimum delay. With the use of real-time applications such as Voice-over-IP (VoIP) increasing, the requirement for bandwidth allocation is also increasing.

Bandwidth management addresses questions such as:

• Who gets how much access to specific applications?
• What priority level should you give to each type of traffic?
• Which traffic must have guaranteed delivery?
• How much bandwidth should be allotted to guarantee delivery?

Bandwidth management also allows you to configure the allowed output for an interface to match what the network can handle. This helps reduce delays and dropped packets at the next routing device. For example, you can set the WAN interface speed to 1024 kbps (or less) if the broadband device connected to the WAN port has an upstream speed of 1024 kbps.

17.1.1 Bandwidth Classes and Filters

Use bandwidth classes and sub-classes to allocate specific amounts of bandwidth capacity (bandwidth budgets). Configure a bandwidth filter to define a bandwidth class (or sub-class) based on a specific application and/or subnet. Use the Bandwidth Class Setup Screen to set up a bandwidth class's name, bandwidth allotment, and bandwidth filter. You can configure up to one bandwidth filter per bandwidth class. You can also configure bandwidth classes without bandwidth filters. However, it is recommended that you configure sub-classes with filters for any classes that you configure without filters. The ZyXEL Device leaves the bandwidth budget allocated and unused for a class that does not have a filter or sub-classes with filters. View your configured bandwidth classes and sub-classes in the Bandwidth Class Setup Screen.

The total of the configured bandwidth budgets for sub-classes cannot exceed the configured bandwidth budget speed of the parent class.

17.1.2 Proportional Bandwidth Allocation

Bandwidth management allows you to define how much bandwidth each class gets; however, the actual bandwidth allotted to each class decreases or increases in proportion to actual available bandwidth.

17.1.3 Application-based Bandwidth Management

You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E-mail and Video for example).

17.1.4 Subnet-based Bandwidth Management

You can create bandwidth classes based on subnets. The following figure shows LAN subnets. You could configure one bandwidth class for subnet A and another for subnet B.

Figure 113 Subnet-based Bandwidth Management Example

17.1.5 Application- and Subnet-based Bandwidth Management

You could also create bandwidth classes based on a combination of a subnet and an application. The following example table shows bandwidth allocations for application specific traffic from separate LAN subnets.

Table 85 Application and Subnet-based Bandwidth Management Example

TRAFFIC TYPE	FROM SUBNET A	FROM SUBNET B
VoIP	64 Kbps	64 Kbps
Web	64 Kbps	64 Kbps
FTP	64 Kbps	64 Kbps
E-mail	64 Kbps	64 Kbps
Video	64 Kbps	64 Kbps

17.1.6 Scheduler

The scheduler divides up an interface's bandwidth among the bandwidth classes. The ZyXEL Device has two types of schedulers: fairness-based and priority-based.

With the priority-based scheduler, the ZyXEL Device forwards traffic from bandwidth classes according to the priorities that you assign to the bandwidth classes. The larger a bandwidth class's priority number is, the higher the priority. Assign real-time applications (like those using audio or video) a higher priority number to provide smoother operation.

The ZyXEL Device divides bandwidth equally among bandwidth classes when using the fairness-based scheduler; thus preventing one bandwidth class from using all of the interface's bandwidth.

17.1.7 Maximize Bandwidth Usage

This option allows the ZyXEL Device to divide up any available bandwidth on the interface (including unallocated bandwidth and any allocated bandwidth that a class is not using) among the bandwidth classes that require more bandwidth.

When you enable maximize bandwidth usage, the ZyXEL Device first makes sure that each bandwidth class gets up to its bandwidth allotment. Next, the ZyXEL Device divides up an interface's available bandwidth (bandwidth that is unbudgeted or unused by the classes) depending on how many bandwidth classes require more bandwidth and on their priority levels. When only one class requires more bandwidth, the ZyXEL Device gives extra bandwidth to that class.

When multiple classes require more bandwidth, the ZyXEL Device gives the highest priority classes the available bandwidth first (as much as they require, if there is enough available bandwidth), and then to lower priority classes if there is still bandwidth available. The ZyXEL Device distributes the available bandwidth equally among classes with the same priority level.

17.1.7.1 Reserving Bandwidth for Non-Bandwidth Class Traffic

Do the following three steps to configure the ZyXEL Device to allow bandwidth for traffic that is not defined in a bandwidth filter.

1 Leave some of the interface's bandwidth unbudgeted.
2 Do not enable the interface's Maximize Bandwidth Usage option.
3 Do not enable bandwidth borrowing on the sub-classes (see Section 17.1.8 on page 205).

17.1.7.2 Maximize Bandwidth Usage Example

Here is an example of a ZyXEL Device that has maximize bandwidth usage enabled on an interface. The following table shows each bandwidth class's bandwidth budget. The classes are set up based on subnets. The interface is set to 10240 kbps. Each subnet is allocated 2048 kbps. The unbudgeted 2048 kbps allows traffic not defined in any of the bandwidth filters to go out when you do not select the maximize bandwidth option.

Table 86 Maximize Bandwidth Usage Example

BANDWIDTH CLASSES AND ALLOTMENTS
Root Class: 10240 kbps	Administration: 2048 kbps
	Sales: 2048 kbps
	Marketing: 2048 kbps
	Research: 2048 kbps

The ZyXEL Device divides up the unbudgeted 2048 kbps among the classes that require more bandwidth. If the administration department only uses 1024 kbps of the budgeted 2048 kbps, the ZyXEL Device also divides the remaining 1024 kbps among the classes that require more bandwidth. Therefore, the ZyXEL Device divides a total of 3072 kbps of unbudgeted and unused bandwidth among the classes that require more bandwidth.

17.1.7.3 Priority-based Allotment of Unused and Unbudgeted Bandwidth

The following table shows the priorities of the bandwidth classes and the amount of bandwidth that each class gets.

Table 87 Priority-based Allotment of Unused and Unbudgeted Bandwidth Example

BANDWIDTH CLASSES, PRIORITIES AND ALLOTMENTS
Root Class: 10240 kbps	Administration: Priority 4, 1024 kbps
	Sales: Priority 6, 3584 kbps
	Marketing: Priority 6, 3584 kbps
	Research: Priority 5, 2048 kbps

Suppose that all of the classes except for the administration class need more bandwidth.

• Each class gets up to its budgeted bandwidth. The administration class only uses 1024 kbps of its budgeted 2048 kbps.

• The sales and marketing are first to get extra bandwidth because they have the highest priority (6). If they each require 1536 kbps or more of extra bandwidth, the ZyXEL Device divides the total 3072 kbps total of unbudgeted and unused bandwidth equally between the sales and marketing departments (1536 kbps extra to each for a total of 3584 kbps for each) because they both have the highest priority level.

• Research requires more bandwidth but only gets its budgeted 2048 kbps because all of the unbudgeted and unused bandwidth goes to the higher priority sales and marketing classes.

17.1.7.4 Fairness-based Allotment of Unused and Unbudgeted Bandwidth

The following table shows the amount of bandwidth that each class gets.

Table 88 Fairness-based Allotment of Unused and Unbudgeted Bandwidth Example

BANDWIDTH CLASSES AND ALLOTMENTS
Root Class: 10240 kbps	Administration: 1024 kbps
	Sales: 3072 kbps
	Marketing: 3072 kbps
	Research: 3072 kbps

Suppose that all of the classes except for the administration class need more bandwidth.

Each class gets up to its budgeted bandwidth. The administration class only uses 1024 kbps of its budgeted 2048 kbps.
- The ZyXEL Device divides the total 3072 kbps total of unbudgeted and unused bandwidth equally among the other classes. 1024 kbps extra goes to each so the other classes each get a total of 3072 kbps

17.1.8 Bandwidth Borrowing

Bandwidth borrowing allows a sub-class to borrow unused bandwidth from its parent class, whereas maximize bandwidth usage allows any bandwidth class to borrow any unused or unbudgeted bandwidth on the whole interface.

Enable bandwidth borrowing on a sub-class to allow the sub-class to use the parent class's unused bandwidth. The parent class's unused bandwidth is given to the highest priority subclass first (see Section 17.1.8.1 on page 206).

The total of the bandwidth allotments for sub-classes cannot exceed the bandwidth allotment of the parent class. The ZyXEL Device uses the scheduler to divide the parent class's unused bandwidth among the sub-classes that have bandwidth borrowing enabled.

17.1.8.1 Bandwidth Borrowing Example

Here is an example of bandwidth management with classes configured for bandwidth borrowing. The classes are set up based on departments and individuals within certain departments.

Table 89 Bandwidth Borrowing Example

BANDWIDTH CLASSES AND BANDWIDTH BORROWING SETTINGS
Root Class:	Administration: Borrowing Enabled
	Sales: Borrowing Disabled
	Marketing: Borrowing Enabled
	Research: Borrowing Enabled

• The Sales class cannot borrow unused bandwidth from the Root class because the Sales class has bandwidth borrowing disabled.

17.1.8.2 Maximize Bandwidth Usage With Bandwidth Borrowing

If you configure both maximize bandwidth usage (on the interface) and bandwidth borrowing (on individual sub-classes), the ZyXEL Device functions as follows.

1 The ZyXEL Device sends traffic according to each bandwidth class's bandwidth budget.
2 The ZyXEL Device assigns a parent class's unused bandwidth to its sub-classes that have more traffic than their budgets and have bandwidth borrowing enabled. The ZyXEL Device gives priority to sub-classes of higher priority and treats classes of the same priority equally.
3 The ZyXEL Device assigns any remaining unused or unbudgeted bandwidth on the interface to any class that requires it. The ZyXEL Device gives priority to classes of higher priority and treats classes of the same level equally.
4 If the bandwidth requirements of all of the traffic classes are met and there is still some unbudgeted bandwidth, the ZyXEL Device assigns it to traffic that does not match any of the classes.

17.1.9 Over Allotment of Bandwidth

You can set the bandwidth management speed for an interface higher than the interface's actual transmission speed. Higher priority traffic gets to use up to its allocated bandwidth, even if it takes up all of the interface's available bandwidth. This could stop lower priority traffic from being sent. The following is an example.

Table 90 Over Allotment of Bandwidth Example

BANDWIDTH CLASSES, ALLOTMENTS	PRIORITY
Actual outgoing bandwidth available on the interface: 1000 kbps

Table 90 Over Allotment of Bandwidth Example

BANDWIDTH CLASSES, ALLOTMENTS		PRIORITY
Root Class: 1500 kbps (same as Speed setting)	VoIP traffic (Service = SIP): 500 Kbps	High
	NetMeeting traffic (Service = H.323): 500 kbps	High
	FTP (Service = FTP): 500 Kbps	Medium

If you use VoIP and NetMeeting at the same time, the device allocates up to 500 Kbps of bandwidth to each of them before it allocates any bandwidth to FTP. As a result, FTP can only use bandwidth when VoIP and NetMeeting do not use all of their allocated bandwidth.

Suppose you try to browse the web too. In this case, VoIP, NetMeeting and FTP all have higher priority, so they get to use the bandwidth first. You can only browse the web when VoIP, NetMeeting, and FTP do not use all 1000 Kbps of available bandwidth.

CHAPTER 18 Remote MGMT

Use these screens to control which computers can use which services to access the ZyXEL Device on each interface.

18.1 Remote Management Overview

Remote management allows you to determine which services/protocols can access which ZyXEL Device interface (if any) from which computers.

You may manage your ZyXEL Device from a remote location via:

• Internet (WAN only)
  ALL (LAN and WAN)
  LAN only
• Neither (Disable).

To disable remote management of a service, select Disable in the corresponding Server Access field.

You may only have one remote management session running at a time. The ZyXEL Device automatically disconnects a remote management session of lower priority when another remote management session of higher priority starts. The priorities for the different types of remote management sessions are as follows.

1 Telnet
2 HTTP

18.1.1 Remote Management Limitations

Remote management over LAN or WAN will not work when:

1 You have disabled that service in one of the remote management screens.
2 The IP address in the Secured Client IP field does not match the client IP address. If it does not match, the ZyXEL Device will disconnect the session immediately.
3 There is already another remote management session with an equal or higher priority running. You may only have one remote management session running at one time.

18.1.2 Remote Management and NAT

When NAT is enabled:

• Use the ZyXEL Device's WAN IP address when configuring from the WAN.
• Use the ZyXEL Device's LAN IP address when configuring from the LAN.

18.1.3 System Timeout

There is a default system management idle timeout of five minutes (three hundred seconds). The ZyXEL Device automatically logs you out if the management session remains idle for longer than this timeout period. The management session does not time out when a statistics screen is polling. You can change the timeout period in the SYSTEM General screen.

18.3 SNMP

Simple Network Management Protocol (SNMP) is a protocol used for exchanging management information between network devices. SNMP is a member of the TCP/IP protocol suite. Your ZyXEL Device supports SNMP agent functionality, which allows a manager station to manage and monitor the ZyXEL Device through the network. The ZyXEL Device supports SNMP version one (SNMPv1) and version two (SNMPv2). The next figure illustrates an SNMP management operation.

Note: SNMP is only available if TCP/IP is configured.

Figure 121 SNMP Management Model

An SNMP managed network consists of two main types of component: agents and a manager.

An agent is a management software module that resides in a managed device (the ZyXEL Device). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices.

The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects.

SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:

• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.

18.3.1 Supported MIBs

The ZyXEL Device supports MIB II that is defined in RFC-1213 and RFC-1215. The focus of the MIBs is to let administrators collect statistical data and monitor status and performance.

18.3.2 SNMP Traps

The ZyXEL Device will send traps to the SNMP manager when any one of the following events occurs:

Table 98 SNMP Traps

TRAP #	TRAP NAME	DESCRIPTION
0	coldStart (defined in RFC-1215)	A trap is sent after booting (power on).
1	warmStart (defined in RFC-1215)	A trap is sent after booting (software reboot).
4	authenticationFailure (defined in RFC-1215)	A trap is sent to the manager when receiving any SNMP get or set requirements with the wrong community (password).
6	whyReboot (defined in ZYXEL-MIB)	A trap is sent with the reason of restart before rebooting when the system is going to restart (warm start).
6a	For intentional reboot:	A trap is sent with the message "System reboot by user!" if reboot is done intentionally, (for example, download new files, Cl command "sys reboot", etc.).
6b	For fatal error:	A trap is sent with the message of the fatal code if the system reboots because of fatal errors.

CHAPTER 19

UPnP

Use this screen to set up UPnP.

19.1 Introducing Universal Plug and Play

Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use.

19.1.1 How do I know if I'm using UPnP?

UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP compatible device installed on your network will appear as a separate icon. Selecting the icon of a UPnP device will allow you to access the information and properties of that device.

19.1.2 NAT Traversal

UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following:

• Dynamic port mapping
• Learning public IP addresses
• Assigning lease times to mappings

Windows Messenger is an example of an application that supports NAT traversal and UPnP.

See Chapter 8 on page 127 for further information about NAT.

19.1.3 Cautions with UPnP

The automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments.

All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention.

19.2 UPnP and ZyXEL

ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP™ Implementers Corp. (UIC). ZyXEL's UPnP implementation supports Internet Gateway Device (IGD) 1.0.

See the following sections for examples of installing and using UPnP.

CHAPTER 20

System

Use this screen to set up general system settings, change the system mode, change the password, configure the DDNS server settings, and set the current date and time.

20.1 System Features Overview

20.1.1 System Name

System Name is for identification purposes. However, because some ISPs check this name you should enter your computer's "Computer Name".

• In Windows 95/98 click Start, Settings, Control Panel, Network. Click the Identification tab, note the entry for the Computer Name field and enter it as the System Name.
• In Windows 2000, click Start, Settings and Control Panel and then double-click System. Click the Network Identification tab and then the Properties button. Note the entry for the Computer name field and enter it as the System Name.
• In Windows XP, click Start, My Computer, View system information and then click the Computer Name tab. Note the entry in the Full computer name field and enter it as the ZyXEL Device System Name.

20.1.2 Domain Name

The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave this blank, the domain name obtained by DHCP from the ISP is used. While you must enter the host name (System Name) on each individual computer, the domain name can be assigned from the ZyXEL Device via DHCP.

20.1.3 DNS Server Address Assignment

Use DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it.

The ZyXEL Device can get the DNS server addresses in the following ways.

1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server fields in the SYSTEM General screen.
2 If the ISP did not give you DNS server information, leave the DNS Server fields in the SYSTEM General screen set to 0.0.0.0 for the ISP to dynamically assign the DNS server IP addresses.

20.1.4 Dynamic DNS

Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also access your FTP server or Web site on your own computer using a domain name (for instance myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don't know your IP address.

First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a domain name. The Dynamic DNS service provider will give you a password or key.

Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname.

Note: If you have a private WAN IP address, then you cannot use Dynamic DNS.

20.1.5 Pre-defined NTP Time Servers List

The ZyXEL Device uses the following pre-defined list of NTP time servers if you do not specify a time server or it cannot synchronize with the time server you specified.

Note: The ZyXEL Device can use this pre-defined list of time servers regardless of the Time Protocol you select.

When the ZyXEL Device uses the pre-defined list of NTP time servers, it randomly selects one server and tries to synchronize with it. If the synchronization fails, then the ZyXEL Device goes through the rest of the list in order from the first one tried until either it is successful or all the pre-defined NTP time servers have been tried.

CHAPTER 21 Logs

Use these screens to look at log entries and alerts and to configure the ZyXEL Device's log and alert settings.

21.1 Logs Overview

For a list of log messages, see Section 21.3 on page 252.

21.1.1 Alerts

An alert is a type of log that warrants more serious attention. Some categories such as System Errors consist of both logs and alerts.

21.1.2 Syslog Logs

There are two types of syslog: event logs and traffic logs. The device generates an event log when a system event occurs, for example, when a user logs in or the device is under attack. The device generates a traffic log when a "session" is terminated. A traffic log summarizes the session's type, when it started and stopped the amount of traffic that was sent and received and so on. An external log analyzer can reconstruct and analyze the traffic flowing through the device after collecting the traffic logs.

Table 107 Syslog Logs

LOGMESSAGE	DESCRIPTION
Event Log: <Facility*8 + Severity>Mon dd hr:mm:ss hostname src="<srcIP:srcPort>" dst="<dstIP:dstPort>" msg="<msg>" note="<note>" devID="<mac address>" cat="<category>"	This message is sent by the system ("RAS" displays as the system name if you haven't configured one) when the router generates a syslog. The facility is defined in the Log Settings screen. The severity is the log's syslog class. The definition of messages and notes are defined in the various log charts throughout this chapter. The "devID" is the MAC address of the router's LAN port. The "cat" is the same as the category in the router's logs.
Traffic Log: <Facility*8 + Severity>Mon dd hr:mm:ss hostname src="<srcIP:srcPort>" dst="<dstIP:dstPort>" msg="Traffic Log" note="Traffic Log" devID="<mac address>" cat="Traffic Log" duration=seconds sent=sentBytes rcvd=receiveBytes dir="/from:to/" proto=IPProtocolID proto="serviceName"	This message is sent by the device when the connection (session) is closed. The facility is defined in the Log Settings screen. The severity is the traffic log type. The message and note always display "Traffic Log". The "proto" field lists the service name.

23.5 Telephone Problems

Table 131 Troubleshooting Telephone

PROBLEM	CORRECTIVE ACTION
The telephone port won't work or the telephone lacks a dial tone.	Check the telephone connections and telephone wire. Make sure you have the VoIP SIP Settings screen properly configured.
I can access the Internet, but cannot make VoIP calls.	Make sure you have the VoIP SIP Settings screen properly configured. One of the PHONE lights should come on. Make sure that your telephone is connected to the corresponding PHONE port. You can also check the VoIP status in the Status screen. If the VoIP settings are correct, use speed dial to make peer-to-peer calls. If you cannot make a call using speed dial, there may be something wrong with the SIP server, contact your VoIP service provider.
I cannot call from one of the ZyXEL Device's phone ports to the other phone port.	You cannot call the SIP number of the SIP account that you are using to make a call. The ZyXEL Device generates a busy tone and does not attempt to establish a call if the SIP number you dial matches the outgoing SIP number of the phone port you are using. For example, if you set Phone 1 to use SIP account 1 and set Phone 2 to use SIP account 2, then you can use Phone 1 to call to SIP account 2's SIP number or Phone 2 to call to SIP account 1's SIP number.

23.6 Problems With Multiple SIP Accounts

You can set up two SIP accounts on your ZyXEL Device and your ZyXEL Device is equipped with two phone ports. By default your ZyXEL Device uses SIP account 1 with both phone ports for outgoing calls, and it uses SIP accounts 1 and 2 for incoming calls. With this setting, you always use SIP account 1 for your outgoing calls and you cannot distinguish which SIP account the calls are coming in through. If you want to control the use of different dialing plans for accounting purposes or other reasons, you need to configure your phone ports in order to control which SIP account you are using when placing or receiving calls.

23.6.1 Outgoing Calls

The following figure represents the default behavior of your ZyXEL Device when two SIP accounts are configured and you are using two phones. When you place a call from phone 1 or phone 2, the ZyXEL Device will use SIP account 1.

Figure 161 Outgoing Calls: Default

In the next example, phone port 1 is configured to use SIP account 1 and phone port 2 is configured to use SIP account 2. In this case, every time you place a call through phone port 1, you are using your SIP account 1. Similarly, every time you place a call through phone port 2, you are using your SIP account 2. To apply these configuration changes you need to configure the Analog Phone screen. See Section 10.2 on page 155.

Figure 162 Outgoing Calls: Individual Configuration

23.6.2 Incoming Calls

The following example shows the default behavior of your ZyXEL Device for incoming calls when two SIP accounts are configured and you are using two phones. When a call comes in from your SIP account 1, the phones connected to both phone port 1 and phone port 2 ring. Similarly, when a call comes in from your SIP account 2, the phones connected to both phone port 1 and phone port 2 ring. In either case you are not sure which SIP account the call is coming from.

Figure 163 Incoming Calls: Default

In the next example, phone port 1 is configured to use SIP account 1 and phone port 2 is configured to use SIP account 2 for incoming calls. In this case, every time you receive a call from your SIP account 1, the phone connected to phone port 1 rings. Similarly, every time you receive a call from your SIP account 2, the phone connected to phone port 2 rings. To apply these configuration changes you need to configure the Analog Phone screen. See Section 10.2 on page 155.

Firmware Upgrade	Download new firmware (when available) from the ZyXEL web site and use the web configurator, an FTP or a TFTP tool to put it on the ZyXEL Device.Note: Only upload firmware for your specific model!
IEEE 802.11g Wireless LAN	The ZyXEL Device can serve as an IEEE 802.11g wireless access point. Expand your network by allowing IEEE 802.11g and IEEE 802.11b devices to connect to your network.
Wireless Security	The ZyXEL Device supports WEP encryption for basic security as well as WPA and WPA2 security standards.You can also use OTIST to easily configure your wireless security on both your ZyXEL Device and compatible wireless clients.
MAC Address Filter	Allow or deny access to your wired or wireless network based on the MAC addresses of the computers communicating with your network.
Any IP	The Any IP feature allows a computer to access the Internet and the ZyXEL Device without changing the network settings (such as IP address and subnet mask) of the computer, when the IP addresses of the computer and the ZyXEL Device are not in the same subnet.
Configuration Backup & Restoration	Make a copy of the ZyXEL Device's configuration and put it back on the ZyXEL Device later if you decide you want to revert back to an earlier configuration.
Network Address Translation (NAT)	Each computer on your network must have its own unique IP address.Use NAT to convert a single public IP address to multiple private IP addresses for the computers on your network.
Port Forwarding	If you have a server (mail or web server for example) on your network, then use this feature to let people access it from the Internet.
DHCP (Dynamic Host Configuration Protocol)	Use this feature to have the ZyXEL Device assign IP addresses, an IP default gateway and DNS servers to computers on your network.
Dynamic DNS Support	With Dynamic DNS (Domain Name System) support, you can use a fixed URL, www.zyxel.com for example, with a dynamic IP address. You must register for this service with a Dynamic DNS service provider.
IP Multicast	IP Multicast is used to send traffic to a specific group of computers. The ZyXEL Device supports versions 1 and 2 of IGMP (Internet Group Management Protocol) used to join multicast groups (see RFC 2236).
IP Alias	IP Alias allows you to subdivide a physical network into logical networks over the same Ethernet interface with the ZyXEL Device itself as the gateway for each subnet.
Time and Date	Get the current time and date from an external server when you turn on your ZyXEL Device. You can also set the time manually. These dates and times are then used in logs.
Logging and Tracing	Use packet tracing and logs for troubleshooting. You can send logs from the ZyXEL Device to an external UNIX syslog server.

APPENDIX C

IP Addresses and Subnetting

This appendix introduces IP addresses, IP address classes and subnet masks. You use subnet masks to subdivide a network into smaller logical networks.

Introduction to IP Addresses

An IP address has two parts: the network number and the host ID. Routers use the network number to send packets to the correct network, while the host ID identifies a single device on the network.

An IP address is made up of four octets, written in dotted decimal notation, for example, 192.168.1.1. (An octet is an 8-digit binary number. Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in decimal.)

There are several classes of IP addresses. The first network number (192 in the above example) defines the class of IP address. These are defined as follows:

Class A: 0 to 127
Class B: 128 to 191
Class C: 192 to 223
Class D: 224 to 239
Class E: 240 to 255

IP Address Classes and Hosts

The class of an IP address determines the number of hosts you can have on your network.

• In a class A address the first octet is the network number, and the remaining three octets are the host ID.
• In a class B address the first two octets make up the network number, and the two remaining octets make up the host ID.
• In a class C address the first three octets make up the network number, and the last octet is the host ID.

The following table shows the network number and host ID arrangement for classes A, B and C.

Table 136 Classes of IP Addresses

IP ADDRESS	OCTET 1	OCTET 2	OCTET 3	OCTET 4
Class A	Network number	Host ID	Host ID	Host ID
Class B	Network number	Network number	Host ID	Host ID
Class C	Network number	Network number	Network number	Host ID

An IP address with host IDs of all zeros is the IP address of the network (192.168.1.0 for example). An IP address with host IDs of all ones is the broadcast address for that network (192.168.1.255 for example). Therefore, to determine the total number of hosts allowed in a network, deduct two as shown next:

• A class C address (1 host octet: 8 host bits) can have 2^8 - 2 , or 254 hosts.
• A class B address (2 host octets: 16 host bits) can have 2^16 - 2 , or 65534 hosts.

A class A address (3 host octets: 24 host bits) can have 2^24 - 2 hosts, or approximately 16 million hosts.

IP Address Classes and Network ID

The value of the first octet of an IP address determines the class of an address.

Class A addresses have a 0 in the leftmost bit.
Class B addresses have a 1 in the leftmost bit and a 0 in the next leftmost bit.
Class C addresses start with 1 1 0 in the first three leftmost bits.
- Class D addresses begin with 1 1 1 0. Class D addresses are used for multicasting, which is used to send information to groups of computers.
- There is also a class E. It is reserved for future use.

The following table shows the allowed ranges for the first octet of each class. This range determines the number of subnets you can have in a network.

Table 137 Allowed IP Address Range By Class

CLASS	ALLOWED RANGE OF FIRST OCTET (BINARY)	ALLOWED RANGE OF FIRST OCTET (DECIMAL)
Class A	00000000 to 01111111	0 to 127
Class B	10000000 to 10111111	128 to 191
Class C	11000000 to 11011111	192 to 223
Class D	11100000 to 11101111	224 to 239
Class E(reserved)	11110000 to 11111111	240 to 255

Subnet Masks

A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation).

A subnet mask has 32 bits. If a bit in the subnet mask is a "1" then the corresponding bit in the IP address is part of the network number. If a bit in the subnet mask is "0" then the corresponding bit in the IP address is part of the host ID.

Subnet masks are expressed in dotted decimal notation just like IP addresses. The "natural" masks for class A, B and C IP addresses are as follows.

Table 138 "Natural" Masks

CLASS	NATURAL MASK
A	255.0.0.0
B	255.255.0.0
C	255.255.255.0

Subnetting

With subnetting, the class arrangement of an IP address is ignored. For example, a class C address no longer has to have 24 bits of network number and 8 bits of host ID. With subnetting, some of the host ID bits are converted into network number bits.

By convention, subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.

Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a “/” followed by the number of bits in the mask after the address.

For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with mask 255.255.255.128.

The following table shows all possible subnet masks for a class "C" address using both notations.

Table 139 Alternative Subnet Mask Notation

SUBNET MASK	SUBNET MASK “1” BITS	LAST OCTET BIT VALUE	DECIMAL
255.255.255.0	/24	0000 0000	0
255.255.255.128	/25	1000 0000	128
255.255.255.192	/26	1100 0000	192
255.255.255.224	/27	1110 0000	224
255.255.255.240	/28	1111 0000	240
255.255.255.248	/29	1111 1000	248
255.255.255.252	/30	1111 1100	252

The first mask shown is the class "C" natural mask. Normally if no mask is specified it is understood that the natural mask is being used.

Example: Two Subnets

As an example, you have a class "C" address 192.168.1.0 with subnet mask of 255.255.255.0.

Table 140 Two Subnets Example

IP/SUBNET MASK	NETWORK NUMBER	HOST ID
IP Address	192.168.1.	0
IP Address (Binary)	11000000.10101000.00000001.	00000000
Subnet Mask	255.255.255.	0
Subnet Mask (Binary)	11111111.11111111.11111111.	00000000

The first three octets of the address make up the network number (class "C").

To make two networks, divide the network 192.168.1.0 into two separate subnets by converting one of the host ID bits of the IP address to a network number bit. The "borrowed" host ID bit can be either "0" or "1" thus giving two subnets; 192.168.1.0 with mask 255.255.255.128 and 192.168.1.128 with mask 255.255.255.128.

Note: In the following charts, shaded/bolded last octet bit values indicate host ID bits "borrowed" to make network ID bits. The number of "borrowed" host ID bits determines the number of subnets you can have. The remaining number of host ID bits (after "borrowing") determines the number of hosts you can have on each subnet.

Table 141 Subnet 1

IP/SUBNET MASK	NETWORK NUMBER	LAST OCTET BIT VALUE
IP Address	192.168.1.	0
IP Address (Binary)	11000000.10101000.00000001.	00000000

Subnet Mask (Binary)	11111111.11111111.11111111.	10000000
Subnet Address: 192.168.1.0	Lowest Host ID: 192.168.1.1
Broadcast Address: 192.168.1.127	Highest Host ID: 192.168.1.126

Table 142 Subnet 2

IP/SUBNET MASK	NETWORK NUMBER	LAST OCTET BIT VALUE
IP Address	192.168.1.	128
IP Address (Binary)	11000000.10101000.00000001.	10000000
Subnet Mask	255.255.255.	128
Subnet Mask (Binary)	11111111.11111111.11111111.	10000000
Subnet Address: 192.168.1.128	Lowest Host ID: 192.168.1.129
Broadcast Address: 192.168.1.255	Highest Host ID: 192.168.1.254

Host IDs of all zeros represent the subnet itself and host IDs of all ones are the broadcast address for that subnet, so the actual number of hosts available on each subnet in the example above is 2^7 - 2 or 126 hosts for each subnet.

192.168.1.0 with mask 255.255.255.128 is the subnet itself, and 192.168.1.127 with mask 255.255.255.128 is the directed broadcast address for the first subnet. Therefore, the lowest IP address that can be assigned to an actual host for the first subnet is 192.168.1.1 and the highest is 192.168.1.126. Similarly the host ID range for the second subnet is 192.168.1.129 to 192.168.1.254.

Example: Four Subnets

The above example illustrated using a 25-bit subnet mask to divide a class "C" address space into two subnets. Similarly to divide a class "C" address into four subnets, you need to "borrow" two host ID bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits (1111111.1111111.1111111.1100000) or 255.255.255.192. Each subnet contains 6 host ID bits, giving 2^6-2 or 62 hosts for each subnet (all zeroes is the subnet itself, all ones is the broadcast address on the subnet).

Example Eight Subnets

Similarly use a 27-bit mask to create eight subnets (000, 001, 010, 011, 100, 101, 110 and 111).

The following table shows class C IP address last octet values for each subnet.

Subnetting With Class A and Class B Networks.

For class "A" and class "B" addresses the subnet mask also determines which bits are part of the network number and which are part of the host ID.

A class “B” address has two host ID octets available for subnetting and a class “A” address has three host ID octets (see Table 136 on page 298) available for subnetting.

The following table is a summary for class "B" subnet planning.

APPENDIX D SIP Passthrough

Enabling/Disabling the SIP ALG

You can turn off the ZyXEL Device SIP ALG to avoid retranslating the IP address of an existing SIP device that is using STUN. If you want to use STUN with a SIP client device (a SIP phone or IP phone for example) behind the ZyXEL Device, use the ip alg disable ALG_SIP command to turn off the SIP ALG.

Signaling Session Timeout

Most SIP clients have an "expire" mechanism indicating the lifetime of signaling sessions. The SIP UA sends registration packets to the SIP server periodically and keeps the session alive in the ZyXEL Device.

If the SIP client does not have this mechanism and makes no call during the ZyXEL Device SIP timeout default (60 minutes), the ZyXEL Device SIP ALG drops any incoming calls after the timeout period. You can use the ip alg sipttimeout command to change the timeout value.

Audio Session Timeout

If no voice packets go through the SIP ALG before the timeout period default (5 minutes) expires, the SIP ALG does not drop the call but blocks all voice traffic and deletes the audio session. You cannot hear anything and you will need to make a new call to continue your conversation.

APPENDIX E Internal SPTGEN

This appendix introduces Internal SPTGEN. All menus shown in this appendix are example menus meant to show SPTGEN usage. Actual menus for your product may differ.

Internal SPTGEN Overview

Internal SPTGEN (System Parameter Table Generator) is a configuration text file useful for efficient configuration of multiple ZyXEL Devices. Internal SPTGEN lets you configure, save and upload multiple menus at the same time using just one configuration text file - eliminating the need to navigate and configure individual screens for each ZyXEL Device. You can use FTP to get the Internal SPTGEN file. Then edit the file in a text editor and use FTP to upload it again to the same device or another one. See the following sections for details.

The Configuration Text File Format

All Internal SPTGEN text files conform to the following format:

<field identification number = field name = parameter values allowed = input>, 

where (<\mathrm{input}>) is your input conforming to (<\mathrm{parameter}> values allowed>.

The figure shown next is an example of an Internal SPTGEN text file.

Figure 186 Configuration Text File Format: Column Descriptions
/Menu1General Setup
10000000 = Configured <0(No) | 1(Yes)> = 1
10000001 = System Name = Your Device
10000002 = Location = 10000003 = Contact Person's Name = 10000004 = Route IP <0(No) | 1(Yes)> = 1
10000005 = Route IPX <0(No) | 1(Yes)> = 0
10000006 = Bridge <0(No) | 1(Yes)> = 0

Note: DO NOT alter or delete any field except parameters in the Input column.

This appendix introduces Internal SPTGEN. All menus shown in this appendix are example menus meant to show SPTGEN usage. Actual menus for your product may differ.

Internal SPTGEN File Modification - Important Points to Remember

Each parameter you enter must be preceded by one “=” sign and one space.

Some parameters are dependent on others. For example, if you disable the Configured field in menu 1 (see Figure 186 on page 307), then you disable every field in this menu.

If you enter a parameter that is invalid in the Input column, the ZyXEL Device will not save the configuration and the command line will display the Field Identification Number. Figure 187 on page 308, shown next, is an example of what the ZyXEL Device displays if you enter a value other than "0" or "1" in the Input column of Field Identification Number 1000000 (refer to Figure 186 on page 307).

Figure 187 Invalid Parameter Entered: Command Line Example

field value is not legal error:-1  
ROM-t is not saved, error Line ID:10000000

Bootbase Version: V2.02 | 2/22/2001 13:33:11  
RAM: Size = 8192 Kbytes  
FLASH: Intel 8M *2 

The ZyXEL Device will display the following if you enter parameter(s) that are valid.

Internal SPTGEN FTP Download Example

1 Launch your FTP application.
2 Enter "bin". The command "bin" sets the transfer mode to binary.
3 Get "rom-t" file. The command "get" transfers files from the ZyXEL Device to your computer. The name "rom-t" is the configuration filename on the ZyXEL Device.
4 Edit the "rom-t" file using a text editor (do not use a word processor). You must leave this FTP screen to edit.

• Name: This is a short, descriptive name for the service. You can use this one or create a different one, if you like.
• Protocol: This is the type of IP protocol used by the service. If this is TCP/UDP, then the service uses the same port number with TCP and UDP. If this is USER-DEFINED, the Port(s) is the IP protocol number, not the port number.

• Port(s): This value depends on the Protocol.

• If the Protocol is TCP, UDP, or TCP/UDP, this is the IP port number.
  If the Protocol is USER, this is the IP protocol number.

• Description: This is a brief explanation of the applications that use this service or the situations in which this service is used.
