Gateway – Advanced Web Page Group

This page allows you to enable/disable some features of the Wireless Voice Gateway.

 WAN Blocking prevents others on the WAN side from being able to ping your gateway. With

WAN Blocking enabled, your gateway will not respond to pings it receives, effectively ―hiding‖

 Ipsec PassThrough enables IpSec type packets to pass WAN  LAN. IpSec (IP Security) is a

security mechanism used in Virtual Private Networks (VPNs).

 PPTP PassThrough enables PPTP type packets to pass WAN  LAN. PPTP (Point to Point

Tunneling Protocol) is another mechanism sometimes used in VPNs.

 Remote Config Management makes the configuration web pages in your gateway accessible

from the WAN side. Note that page access is limited to only those who know the gateway access

password. When accessing your gateway from a remote location, your must use HTTP port 8080Chapter 2: WEB Configuration

and the WAN IP address of the gateway. For example, if the WAN IP address is 157.254.5.7, you

would navigate to http://157.254.5.7:8080 to reach your gateway.

 Multicast Enable enables multicast traffic to pass WAN LAN. You may need to enable this to

see some types of broadcast streaming and content on the Internet.

 UPnP Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,

access the network and connect to other devices as needed. UPnP devices can automatically

discover the services from other registered UPnP devices on the network.

 NatSipAlg Enable the gateway implements SIP ALG (Application-level gateway). It is enabled by

default and help in solving NAT related problems in client LAN side.

This page enables you to enter the IP address ranges of PCs on your LAN that you don’t want to have outbound

access to the WAN. These PCs can still communicate with each other on your LAN, but packets designated to WAN

addresses are blocked by the gateway.

This page enables you to enter the MAC address of specific PCs on your LAN that you do not wish to

have outbound access to the WAN. As with IP filtering, these PCs can still communicate with each

other through the gateway, but packets they send to WAN addresses are blocked.Chapter 2: WEB Configuration

Illustrations contained in this document are for representation only.

This page allows you to enter ranges of destination ports (applications) that you don’t want your LAN PCs to send packets to. Any packets your LAN PCs send to these destination ports will be blocked.

For example, you could block access to worldwide web browsing (http = port 80) but still allow email

service (SMTP port 25 and POP-3 port 110). To enable port filtering, set Start Port and End Port for

each range, and click Apply. To block only one port, set both Start and End ports with the same value.Chapter 2: WEB Configuration

Illustrations contained in this document are for representation only.

For LAN  WAN communications, the gateway normally only allows you to originate an IP

connection with a PC on the WAN; it will ignore attempts of the WAN PC to originate a connection

onto your PC. This protects you from malicious attacks from outsiders. However, sometimes you may

wish for anyone outside to be able to originate a connection to a particular PC on your LAN if the

destination port (application) matches one you specify.

This page allows you to specify up to 10 such rules. For example, to specify that outsiders should have

access to an FTP server you have running at 192.168.0.5, create a rule with that address and Start Port

=20 and End Port =21 (FTP port ranges) and Protocol = TCP (FTP runs over TCP and the other

transport protocol, UDP), and click Apply. This will cause inbound packets that match to be forwarded

to that PC rather than blocked. As these connections are not tracked, no entry is made for them in the

Connection Table. The same IP address can be entered multiple times with different ports.Chapter 2: WEB Configuration

Some Internet activities, such as interactive gaming, require that a PC on the WAN side of your

gateway be able to originate connections during the game with your game playing PC on the LAN side.

You could use the Advanced-Forwarding web page to construct a forwarding rule during the game,

and then remove it afterwards (to restore full protection to your LAN PC) to facilitate this. Port

triggering is an elegant mechanism that does this work for you, each time you play the game.Chapter 2: WEB Configuration

Illustrations contained in this document are for representation only.

Port Triggering works as follows. Imagine you want to play a particular game with PCs somewhere on

the Internet. You make one time effort to set up a Port Trigger for that game, by entering into Trigger

Range the range of destination ports your game will be sending to, and entering into Target Range

the range of destination ports the other player (on the WAN side) will be sending to (ports your PC’s

game receives on). Application programs like games publish this information in user manuals. Later,

each time you play the game, the gateway automatically creates the forwarding rule necessary. This

rule is valid until 10 minutes after it sees game activity stop. After 10 minutes, the rule becomes

inactive until the next matched outgoing traffic arrives.

For example, suppose you specify Trigger Range from 6660 to 6670 and Target Range from 113 to

113. An outbound packet arrives at the gateway with your game-playing PC source IP address

192.168.0.10, destination port 666 over TCP/IP. This destination port is within the Trigger destined for

port 113 to your game-playing PC at 192.168.0.10.

You can specify up to 10 port ranges on which to trigger.Chapter 2: WEB Configuration

Use this page to designate one PC on your LAN that should be left accessible to all PCs from the

WAN side, for all ports. For example, if you put an HTTP server on this machine, anyone will be able

to access that HTTP server by using your gateway IP address as the destination. A setting of ―0‖

indicates NO DMZ PC. ―Host‖ is another Internet term for a PC connected to the Internet.

8. RIP (Routing Information Protocol) Setup

This feature enables the gateway to be used in small business situations where more than one LAN

(local area network) is installed. The RIP protocol provides the gateway a means to ―advertise‖

available IP routes to these LANs to your cable operator, so packets can be routed properly in this

Your cable operator will advise you during installation if any setting changes are required here.Chapter 2: WEB Configuration

Gateway – Wireless Web Page Group

Important: Changes to the wireless web pages should be made from a PC that is hard

wired to the gateway, i.e. via Ethernet.

The Wireless web pages group enables a variety of settings that can provide secure and reliable

wireless communications for even the most demanding tech-savvy user.

The Wireless Voice Gateway offers a choice of 802.1x, WPA and WPA-PSK authentication of your

PCs to the gateway, 64 and 128 bit WEP encryption of communication between the gateway and your

PCs to guaranty security, and an Access Control List function that enables you to restrict wireless

access to only your specific PCs.

The wireless function will probably work in your home as shipped from the factory, but without the

security features activated. In addition, the factory default wireless channel setting may not provide

optimum changes are recommended from the factory defaults, to secure your wireless communications

and provide optimum performance.

Because your wireless communication travels through the air, the factory default wireless channel

setting may not provide optimum performance in your home if you or your neighbors have other

interfering 2.4GHz devices such as cordless phones. If your wireless PC is experiencing very sluggish

or dramatically slower communication compared with the speed you achieve on your PC that is wired

to the gateway, try changing the channel number. See the 802.11b/g Basic Web Page discussion below

Authentication enables you to restrict your gateway from communicating with any remote wireless

PCs that aren’t yours. The following minimum authentication-related changes to factory defaults are

recommended. See the 802.11b/g Basic and Access Control Web Page discussions below for details.

Network Name (SSID) – Set a unique name you choose

Network Type – Set to Open

Access Control List – Enter your wireless PCs’ MAC addressesChapter 2: WEB Configuration

Chapter 3: Networking

Data communication involves the flow of packets of data from one device to another. These

devices include personal computers, Ethernet and USB hubs, cable modems, digital routers

and switches, and highly integrated devices that combine functions, like the Wireless Cable

The gateway integrates the functionality often found in two separate devices into one. It’s

both a cable modem and an intelligent wireless gateway networking device that can provide a

host of networking features, such as NAT and firewall. Figure 2 illustrates this concept, with

the cable modem (CM) functionality on the left, and networking functionality on the right. In

this figure, the numbered arrows represent communication based on source and destination,

Type of Communication

1. Communication between the Internet and your PCs

Example: The packets created by your request for a page stored at a web site, and the

contents of that page sent to your PC.

2. Communication between your cable company and the cable modem side

Example: When your cable modem starts up, it must initialize with the cable company,

which requires the cable company to communicate directly with the cable modem itself.

3. Communication between your PCs and the networking sideChapter 3: Networking

Illustrations contained in this document are for representation only.

Example: The Wireless Cable Gateway offers a number of built-in web pages which you

can use to configure its networking side; when you communicate with the networking

side, your communication is following this path.

Each packet on the Internet addressed to a PC in your home travels from the Internet down-

stream on the cable company’s system to the WAN side of your Wireless Cable Gateway. There

it enters the Cable Modem section, which inspects the packet, and, based on the results,

proceeds to either forward or block the packet from proceeding on to the Networking section.

Similarly, the Networking section then decides whether to forward or block the packet from

proceeding on to your PC. Communication from your home device to an Internet device works

similarly, but in reverse, with the packet traveling upstream on the cable system.Chapter 3: Networking

Illustrations contained in this document are for representation only.

Cable Modem (CM) Section

The cable modem (or CM) section of your gateway uses EURO-DOCSIS Standard cable modem

technology. EURO-DOCSIS specifies that TCP/IP over Ethernet style data communication be

used between the WAN interface of your cable modem and your cable company.

A EURO-DOCSIS modem, when connected to a Cable System equipped to support such

modems, performs a fully automated initialization process that requires no user intervention.

Part of this initialization configures the cable modem with a CM IP (Cable Modem Internet

Protocol) address, as shown in Figure 3, so the cable company can communicate directly with

The Networking section of your gateway also uses TCP/IP (Transmission Control Protocol/

Internet Protocol) for the PCs you connected on the LAN side. TCP/IP is a networking protocol

that provides communication across interconnected networks, between computers with

diverse hardware architectures and various operating systems.

TCP/IP requires that each communicating device be configured with one or more TCP/IP

stacks, as illustrated by Figure 4. On a PC, you often use software that came with the PC or its

network interface (if you purchased a network interface card separately) to perform this

configuration. To communicate with the Internet, the stack must also be assigned an IP

(Internet Protocol) address. 192.168.100.1 is an example of an IP address. A TCP/IP stack canChapter 3: Networking

Illustrations contained in this document are for representation only.

be configured to get this IP address by various means, including a DHCP server, by you

directly entering it, or sometimes by a PC generating one of its own.

Ethernet requires that each TCP/IP stack on the Wireless Cable Gateway also have associated

with it an Ethernet MAC (Media Access Control) address. MAC addresses are permanently

fixed into network devices at the time of their manufacture. 00:90:64:12:B1:91 is an example

Data packets enter and exit a device through one of its network interfaces. The gateway offers

Ethernet, USB, and 802.11b/g wireless network interfaces on the LAN side and the

EURO-DOCSIS network interface on the WAN side.

When a packet enters a network interface, it is offered to all the TCP/IP stacks associated with

the device side from which it entered. But only one stack can accept it — a stack whose

configured Ethernet address matches the Ethernet destination address inside the packet.

Furthermore, at a packet’s final destination, its destination IP address must also match the IP

address of the stack.

Each packet that enters a device contains source MAC and IP addresses telling where it came

from, and destination MAC and IP addresses telling where it is going to. In addition, the

packet contains all or part of a message destined for some application that is running on the

destination device. IRC used in an Internet instant messaging program, HTTP used by a web

browser, and FTP used by a file transfer program are all examples of applications. Inside theChapter 3: Networking

Illustrations contained in this document are for representation only.

packet, these applications are designated by their port number. Port 80, the standard HTTP

port, is an example of a port number.

The Networking section of the router performs many elegant functions by recognizing

different packet types based upon their contents, such as source and destination MAC

address, IP address, and ports.

Three Networking Modes

Your gateway can be configured to provide connectivity between your cable company and

your home LAN in any one of three Networking Modes: CM, RG, and CH. This mode setting is

under the control of your cable company, who can select the mode to match the level of home

networking support for which you have subscribed. All units ship from the factory set for the

RG mode, but a configuration file which the cable company sends the cable modem section

during its initialization can change it.Chapter 3: Networking

Illustrations contained in this document are for representation only.

CM (Cable Modem) Mode provides basic home networking. In this mode, two IP stacks are

active:Chapter 3: Networking

Illustrations contained in this document are for representation only.

IP Stack 1 - for use by the cable company to communicate with the cable modem section

only. This stack receives its IP address from the cable company during CM initialization. It

uses the MAC address printed on the label attached to the Wireless Cable gateway.

IP Stack 2 - for use by you, the end user, to communicate with the cable modem and

Networking sections, to access the internal web page diagnostics and con guration. This

stack uses a fixed IP address: 192.168.100.1. It uses a MAC address of MAC label + 1 (the

MAC label is found on the bottom of the unit). E.g., if the MAC address is

00:90:64:12:B1:91, this MAC address would be 00:90:64:12:B1:92.

With CM Mode, your cable company must provide one IP address for the CM section, plus one

for each PC you connect from their pool of available addresses. Your cable company may have

you or your installer manually enter these assigned addresses into your PC, or use a DHCP Server to communicate them to your PCs, or use a method that involves you entering host

names into your PCs.

Note that in CM Mode, packets passing to the Internet to/from your PCs do not travel through

any of the IP stacks; instead they are directly bridged between the WAN and LAN sides.Chapter 3: Networking

Illustrations contained in this document are for representation only.

RG (Residential Gateway) Mode provides basic home networking plus NAT (Network Address

Translation). In this mode, three IP stacks are active:Chapter 3: Networking

Illustrations contained in this document are for representation only.

IP Stack 1 - for use by the cable company to communicate with the Cable Modem section

only. This stack receives its IP address from the cable company during CM initialization. It

uses the MAC address printed on the label attached to the Wireless Cable Gateway.

IP Stack 3 - for use by you to remotely (i.e. from somewhere on the WAN side, such as at

your remote workplace) communicate with the Cable Modem and Networking sections, to

remotely access the internal web page diagnostics and configuration. This stack is also

used by your cable company to deliver packets between the Internet and the gateway’s

networking section so they can be routed to/from your PCs. This stack requires an IP

address assigned by the cable company from their pool of available addresses. Your cable

company may have you or your installer manually enter assigned addresses into your

gateway, or use a DHCP Server to communicate them, or use a method that involves you

entering host names. This stack uses a MAC address of MAC label + 2 (the MAC label is

found on the bottom of the unit). E.g., if the MAC address is 00:90:64:12:B1:91, this MAC

address would be 00:90:64:12:B1:93.

IP Stack 5 - for use by you to locally (i.e. from somewhere on the LAN side in your home)

communicate with the Cable Modem and Networking sections, to access the internal web

page diagnostics and configuration. This stack is also used by the gateway’s networking

section to route packets between the gateway’s Networking section and your PCs. This

stack uses a fixed IP address: 192.168.0.1. It uses a MAC address of MAC label + 4 (the

MAC label is found on the bottom of the unit). E.g., if the MAC address isChapter 3: Networking

Illustrations contained in this document are for representation only.

00:90:64:12:B1:91, this MAC address would be 00:90:64:12:B1:95.

With RG Mode, your cable company must provide one IP address for the CM section, plus one

for the Networking section, from their pool of available addresses. With RG Mode, each PC you

connect gets an IP address from a DHCP Server that is part of the Networking section of the

gateway.Chapter 3: Networking

will work with all upgraded cable systems that are Euro-DOCSIS-compliant.

Q. What is Euro-PacketCable and what does it mean?

A. Euro-PacketCable is the industry standard for telephony services that most cable companies are

adopting as they upgrade their systems. Should you ever decide to move, the Wireless Voice Gateway will

work with all upgraded cable systems that are Euro-PacketCable compliant.

Q. What is Xpress Technology and what does it mean?

A. It is one of the popular performance-enhancing WiFi technologies, designed to improve wireless

network efficiency and boost throughput. It is more efficient in mixed environments, and it can work with

802.11a/b/g networks. When Xpress is turned on, aggregate throughput (the sum of the individual

throughput speeds of each client on the network) can improve by up to 27% in 802.11g-only networks,

and up to 75% in mixed networks comprised of 802.11g and 802.11b standard equipment. The

technology achieves higher throughput by by re-packaging data, reducing the number of overhead control

packets, so that more useful data can be sent during a given amount of time.

General Troubleshooting

You can correct most problems you have with your product by consulting the troubleshooting list that

I can’t access the internet.

 Check all of the connections to your Wireless Voice Gateway.

 Your Ethernet card or USB port may not be working. Check each product’s documentation for more

 The Network Properties of your operating system may not be installed correctly or the settings may

be incorrect. Check with your ISP or cable company.

All of the lights are flashing in sequence.

 This means the Wireless Voice Gateway is automatically updating its system software. Please wait

for the lights to stop flashing. The updating process typically lasts less than one minute.

 Do not remove the power supply or reset the Wireless Voice Gateway during this process.

I can’t get the modem to establish an Ethernet connection.

 Even new computers don’t always have Ethernet capabilities – be sure to verify that your computer

has a properly installed Ethernet card and the driver software to support it.

 Check to see that you are using the right type of Ethernet cable.

The modem won’t register a cable connection.

 If the modem is in Initialization Mode, the INTERNET light will be flashing. Call your Cable

Company if it has not completed this 5-step process within 30 minutes, and note which step it is

 The modem should work with a standard RG-6 coaxial cable, but if you’re using a cable other than

the one your Cable Company recommends, or if the terminal connections are loose, it may not work.

Check with your Cable Company to determine whether you’re using the correct cable.

 If you subscribe to video service over cable, the cable signal may not be reaching the modem.

Confirm that good quality cable television pictures are available to the coaxial connector you are

using by connecting a television to it. If your cable outlet is ―dead‖, call your Cable Company.Chapter 4: Additional Information

 Verify that the Cable Modem service is Euro-DOCSIS compliant and Euro-PacketCable compliant

by calling your cable provider.

I don’t hear a dial tone when I use a telephone.

 Telephone service is not activated. If the rightmost light on the Wireless Voice Gateway stays on

while others flash, check with your TSP or cable company.

 If the Wireless Voice Gateway is connected to existing house telephone wiring, make sure that

another telephone service is not connected. The other service can normally be disconnected at the

Network Interface Device located on the outside of the house.

 If using the second line on a two-line telephone, use a 2-line to 1-line adapter cable.
