1.1 Overview
Congratulations on purchasing the RF30 Router from Cometlabs. Combining a router with an Ethernet network switch, the RF30 is a state-of-the-art device that provides everything you need to get your network connected to the Internet over your Cable or DSL connection quickly and easily. The Quick Start Wizard and DHCP Server will get first-time users up and running with minimal fuss and configuration, while sophisticated Quality of Service (QoS) and Load Balancing features grant advanced users total control over their network and Internet connection.
This manual illustrates the many features and functions of the RF30, and even takes you through the various ways you can apply this versatile device to your home or office. Take the time now to familiarize yourself with the RF30.
1.2 Product Highlights
1.2.1 Increased Bandwidth, Scalability and Resilience
With integrated Dual WAN ports, the RF30 combines two broadband lines such as DSL or Cable into one Internet connection, providing optimal bandwidth sharing for multiple PCs on your network, or allowing maximum reliability with network redundancy. Load Balancing enables the RF30 to efficiently balance network traffic across two connections, ideal for small-to-medium businesses that require increased bandwidth, network scalability, and resilience for mission-critical network and Internet applications. Auto failover can also be configured to ensure smooth, continuous service should one connection fail, providing maximum business uptime and productivity, plus uninterrupted service for you and your customers.
1.2.2 Virtual Private Network Support
The RF30 supports comprehensive IPSec VPN protocols for businesses to establish private encrypted tunnels over the Internet to ensure data transmission security among multiple sites, such as a branch office or dial-up connection. Up to 30 simultaneous IPSec VPN connections are possible on the RF30, with performance of up to 30Mbps.
1.2.3 Advanced Firewall Security
Aside from intelligent broadband sharing, the RF30 offers integrated firewall protection with advanced features to secure your network from outside attacks. Stateful Packet Inspection (SPI) determines if a data packet is permitted to enter the private LAN. Denial of Service (DoS) prevents hackers from interrupting network services via malicious attacks. In addition, the RF30 firewall can be configured to alert you via email should your network come under fire, offering both tight network security and peace of mind.
1.2.4 Intelligent Bandwidth Management
The RF30 utilizes Quality of Service (QoS) to give you full control over the priority of both incoming and outgoing data, ensuring that critical data such as customer information moves through your network, even while under a heavy load. Transmission speeds can be throttled to make sure users are not saturating bandwidth required for mission-critical data transfers. Priority types of upload data can also be changed, allowing the RF30 to automatically sort out actual speeds for unmatched convenience.

1.3.3 Rack Mounting
To rack mount the RF30, carefully secure the device to your rack on both sides using the included brackets and screws. See the diagram below for a more detailed explanation.
1.3.4 Cabling
Most Ethernet networks currently use unshielded twisted pair (UTP) cabling. The UTP cable contains eight conductors, arranged in four twisted pairs, and terminated with an RJ45 type connector.
One of the most common causes of networking problems is bad cabling. Make sure that all connected devices are turned on. On the front panel of the RF30, verify that the LAN link and WAN line LEDs are lit. If they are not, check to see that you are using the proper cabling.
Chapter 2: Router Applications
2.1 Overview
Your RF30 Router is a versatile device that can be configured to not only protect your network from malicious attackers, but also ensure optimal usage of available bandwidth with Quality of Service (QoS) and both Inbound and Outbound Load Balancing. Alternatively, the RF30 can also be set to redirect incoming and outgoing network traffic with the Fail Over capability, ensuring minimal downtime and increased reliability.
The following chapter describes how the RF30 can work for you.
2.2 Bandwidth Management with QoS
Quality of Service (QoS) gives you full control over which types of outgoing data traffic should be given priority by the router. By doing so, the router can ensure that latency-sensitive applications like voice, bandwidth-consuming data like gaming packets, or even mission critical files efficiently move through the router even under a heavy load. You can throttle the speed at which different types of outgoing data pass through the router. In addition, you can simply change the priority of different types of upload data and let the router sort out the actual speeds.
2.2.1 QoS Technology
QoS generally involves the prioritization of network traffic. QoS is comprised of three major components: Classifier, Meter, and Scheduler. Each of these components has a distinct role in ensuring that incoming and outgoing data is managed according to user specifications.
The Classifier analyses incoming packets and marks each one according to configured parameters. The Meter communicates the drop priority to the Scheduler and measures the temporal priorities of the output stream against configured parameters. Finally, the
Scheduler schedules each packet for transmission based on information from both the Classifier and the Meter.
2.2.2 QoS Policies for Different Applications
By setting different QoS policies according to the applications you are running, you can use the RF30 to optimize the bandwidth that is being used on your network.
As illustrated in the diagram above, applications such as Voiceover IP (VoIP) require low network latencies to function properly. If bandwidth is being used by other applications such as an FTP server, users using VoIP will experience network lag and/or service interruptions during use. To avoid this scenario, this network has assigned VoIP with a guaranteed bandwidth and higher priority to ensure smooth communications. The FTP server, on the other hand, has been given a maximum bandwidth cap to make sure that regular service to both VoIP and normal Internet applications is uninterrupted.
2.2.3 Guaranteed / Maximum Bandwidth
Setting a Guaranteed Bandwidth ensures that a particular service receives a minimum percentage of bandwidth. For example, you can configure the RF30 to reserve 10% of the available bandwidth for a particular computer on the network to transfer files.
Alternatively you can set a Maximum Bandwidth to restrict a particular application to a fixed percentage of the total throughput. Setting a Maximum Bandwidth of 20% for a file sharing program will ensure that no more than 20% of the available bandwidth will be used for file sharing.
2.2.4 Policy Based Traffic Shaping
Policy Based Traffic Shaping allows you to apply specific traffic policies across a range of IP addresses or ports. This is particularly useful for assigning different policies for different PCs on the network. Policy based traffic shaping lets you better manage your bandwidth, providing reliable Internet and network service to your organization.
2.2.5 Priority Bandwidth Utilization
Assigning priority to a certain service allows the RF30 to give either a higher or lower priority to traffic from this particular service. Assigning a higher priority to an application ensures that it is processed ahead of applications with a lower priority and vice versa.
2.2.6 Management by IP or MAC address
The RF30 can also be configured to apply traffic policies based on a particular IP or MAC address. This allows you to quickly assign different traffic policies to a specific computer on the network.
2.2.7 DiffServ (DSCP Marking)
DiffServ (a.k.a. DSCP Marking) allows you to classify traffic based on IP DSCP values. These markings can be used to identify traffic within the network, and other interfaces can match traffic based on the DSCP markings. DSCP markings are used to decide how packets should be treated, and is a useful tool to give precedence to varying types of data.
2.3 Outbound Traffic
This section outlines some of the ways you can use the RF30 to manage outbound traffic.
2.3.1 Outbound Fail Over
Configuring the RF30 for Outbound Fail Over allows you to ensure that outgoing traffic is uninterrupted by having the RF30 default to WAN2 should WAN1 fail.
In the above example, PC 1 (IP_192.168.2.2) and PC 2 (IP_192.168.2.3) are connected to the Internet via WAN1 (IP_230.100.100.1) on the RF30. Should WAN1 fail, Outbound Fail Over tells the RF30 to reroute outgoing traffic to WAN2 (IP_213.10.10.2). Configuring your RF30 for Outbound Fail Over provides a more reliable connection for your outgoing traffic.
Please refer to appendix H for example settings.
2.3.2 Outbound Load Balancing
Outbound Load Balancing allows the RF30 to intelligently manage outbound traffic based on the amount of load of each WAN connection.
In the above example, PC 1 (IP_192.168.2.2) and PC 2 (IP_192.168.2.3) are connected to the Internet via WAN1 (IP_230.100.100.1) and WAN2 (IP_213.10.10.2) on the RF30. You can configure the RF30 to balance the load of each WAN port with one of two mechanisms:
- Session (by session/by traffic)
- IP Hash (weight of link capability)
The IP Hash mechanism will ensure that the traffic from the same source IP address and destination IP address will go through the same WAN port. This is useful for some server applications that need to identify the source IP address of the client.
By balancing the load between WAN1 and WAN2, your RF30 can ensure that outbound traffic is efficiently handled by making sure that both ports are equally sharing the load, preventing situations where one port is completely saturated by outbound traffic.
Please refer to appendix H for example settings.
2.4 Inbound Traffic
Learn how the RF30 can handle inbound traffic in the following section.
2.4.1 Inbound Fail Over
Configuring the RF30 for Inbound Fail Over allows you to ensure that incoming traffic is uninterrupted by having the RF30 default to WAN2 should WAN1 fail.
In the above example, an FTP Server (IP_192.168.2.2) and an HTTP Server (IP_192.168.2.3) are connected to the Internet via WAN1 (ftp.Cometlabs.dyndns.org) on the RF30. A remote computer is trying to access these servers via the Internet. Under normal circumstances, the remote computer will gain access to the network via WAN1. Should WAN1 fail, Inbound Fail Over tells the RF30 to reroute incoming traffic to WAN2 by using the Dynamic DNS mechanism. Configuring your RF30 for Inbound Fail Over provides a more reliable connection for your incoming traffic.
Please refer to appendix H for example settings.
2.4.2 Inbound Load Balancing
Inbound Load Balancing allows the RF30 to intelligently manage inbound traffic based on the amount of load of each WAN connection.
In the above example, an FTP server (IP_192.168.2.2) and an HTTP server (IP_192.168.2.3) are connected to the Internet via WAN1 (www.Cometlabs2.dyndns.org) and WAN2 (www.Cometlabs3.dyndns.org) on the RF30. Remote PCs are attempting to access the servers via the Internet. Using Inbound Load Balancing, the RF30 can direct incoming requests to the correct WAN port based on group assignment. For example, a sales force can be directed to www.Cometlabs2.dyndns.org, while the R&D group can access www.Cometlabs3.dyndns.org. By balancing the load between WAN1 and WAN2, your RF30 can ensure that inbound traffic is efficiently handled with both ports equally sharing the load, preventing situations where service is slow because one port is completely saturated by inbound traffic.
Please refer to appendix H for example settings.
2.5 DNS Inbound
Using DNS Inbound is a great way to intelligently direct network traffic.
DNS Inbound is a three step process. First, a DNS request is made to the router via a remote PC. The RF30, based on settings specified by the user, will direct the requesting PC to the correct WAN port by replying the selected WAN IP address through the built-in DNS server. The remote PC then accesses the network via the specified WAN port. How the RF30 directs this traffic through the built-in DNS server depends on whether it is configured for Fail Over or Load Balancing.
Learn how to make DNS Inbound on the RF30 work for you in the following section.
2.5.1 DNS Inbound Fail Over
The RF30 can be configured to reply the WAN2 IP address for the DNS domain name request should WAN1 fail.
In the above example, an FTP Server (IP_192.168.2.2) and an HTTP Server (IP_192.168.2.3) are connected to the Internet via WAN1 (IP_200.200.200.1) on the RF30. A remote computer is trying to access these servers via the Internet, and makes a DNS request. The DNS request (www.mydomain.com) will be sent through WAN1 (200.200.200.1) to the built-in DNS server. The DNS server will reply 200.200.200.1 because this is the only active WAN port. Should WAN1 fail, the RF30 will instead reply with WAN2's IP address (100.100.100.1), and the remote PC will gain access to the network via WAN2. By configuring the RF30 for DNS Inbound Fail Over, incoming requests will enjoy increased reliability when accessing your network.
Please refer to appendix H for example settings.
2.5.2 DNS Inbound Load Balancing
DNS Inbound Load Balancing allows the RF30 to intelligently manage inbound traffic based on the amount of load of each WAN connection by assigning the IP address with the lowest traffic load to incoming requests.
In the above example, an FTP server (IP_192.168.2.2) and an HTTP server (IP_192.168.2.3) are connected to the Internet via WAN1 (IP_200.200.200.1) and WAN2 (IP_100.100.100.1) on the RF30. Remote PCs are attempting to access the servers via the Internet by making a DNS request, entering a URL (www.mydomain.com). Using a load balancing algorithm, the RF30 can direct incoming requests to either WAN port based on the amount of load each WAN port is currently experiencing. If WAN2 is experiencing a heavy load, the RF30 responds to incoming DNS requests with WAN1. By balancing the load between WAN1 and WAN2, your RF30 can ensure that inbound traffic is efficiently handled, making sure that both ports are equally sharing the load and preventing situations where service is slow because one port is completely saturated by inbound traffic.
Please refer to appendix H for example settings.
A typical scenario of how traffic is directed with DNS Inbound Load Balancing is illustrated below:
In the example above, the client is making a DNS request. The request is sent to the DNS server of the RF30 through WAN2 (1). WAN2 will route this request to the embedded DNS server of the RF30 (2). The RF30 will analyze the bandwidth of both WAN1 and WAN2 and decide which WAN IP to reply to the request (3). After the decision is made, the RF30 will route the DNS reply to the user through WAN2 (4). The user will receive the DNS reply with the IP address of WAN1 (5). The browser will initiate an HTTP request to the WAN1 IP address (6). The HTTP request will be send to the RF30's URL Host Map (7). The Host Map will then redirect the HTTP request to the HTTP server (8). The HTTP server will reply (9). The URL Host Map will route the packet through WAN1 to the user (10). Finally, the client will receive an HTTP reply packet (11).
2.6 Virtual Private Networking
A Virtual Private Network (VPN) enables you to send data between two computers across a shared or public network in a manner that emulates the properties of a point-to-point private link. As such, it is perfect for connecting branch offices to headquarters across the Internet in a secure fashion.
The following section discusses Virtual Private Networking with the RF30.
2.6.1 General VPN Setup
There are typically three different VPN scenarios. The first is a Gateway to Gateway setup, where two remote gateways communicate over the Internet via a secure tunnel.
The next type of VPN setup is the Gateway to Multiple Gateway setup, where one gateway (Headquarters) is communicating with multiple gateways (Branch Offices) over the Internet. As with all VPNs, data is kept secure with secure tunnels.
The final type of VPN setup is the Client to Gateway. A good example of where this can be applied is when a remote sales person accesses the corporate network over a secure VPN tunnel.
VPN provide a flexible, cost-efficient, and reliable way for companies of all sizes to stay connected. One of the most important steps in setting up a VPN is proper planning. The following sections demonstrate the various ways of using the RF30 to setup your VPN.
2.6.2 VPN Planning - Fail Over
Configuring your VPN with Fail Over allows the RF30 to automatically default to WAN2 should WAN1 fail.
Because the dynamic domain name RF30.cometlabs.com is configured for both WAN1 and WAN2, the active WAN port will announce the domain name through the WAN IP address. The remote gateway will then be able to connect to the VPN through the domain name.
In this Gateway to Gateway example, the RF30 is communicating to a remote gateway using WAN1 through a secure VPN tunnel. Should WAN1 fail, outbound traffic from the RF30 will automatically be redirected to WAN2. This process is completely transparent to the remote gateway, as the RF30 will automatically update the domain name (RF30.cometlabs.com) with the WAN2 IP address.
Configuring a Gateway to Multiple Gateway setup with Fail Over is similar, as shown below:
Configuring the RF30 for Fail Over provides added reliability to your VPN.
2.6.3 Concentrator
The VPN Concentrator provides an easy way for branch offices to connect to headquarters through a VPN tunnel. All branch office traffic will be redirected to the VPN tunnel to headquarters with the exception of LAN-side traffic. This way, all branch offices can connect to each other through headquarters via the headquarters' firewall management. You can also configure the RF30 to function as a VPN Concentrator:
Please refer to appendix H for example settings.
Chapter 3: Getting Started
3.1 Overview
The RF30 is designed to be a powerful and flexible network device that is also easy to use. With an intuitive web-based configuration, the RF30 allows you to administer your network via virtually any Java-enabled web browser and is fully compatible with Linux, Mac OS, and Windows 98/Me/NT/2000/XP operating systems.
The following chapter takes you through the very first steps to configuring your network for the RF30. Take a look and see how easy it is to get your network up and running.
3.2 Before You Begin
The RF30 is a flexible and powerful networking device. To simplify the configuration process and increase the efficiency of your network, consider the following items before setting up your network for the first time:
1. Plan your network
Decide whether you are going to use one or both WAN ports. For one WAN port, you may need a fully qualified domain name either for convenience or if you have a dynamic IP address. If you are going to use both WAN ports, determine whether you are going to use them in fail over mode for increased network reliability or load balancing mode for maximum bandwidth efficiency. See
Chapter 2: Router Applications for more information.
2. Set up your accounts
Have access to the Internet and locate the Internet Service Provider (ISP) configuration information. Each RF30 WAN port must be configured separately, whether you are using a separate ISP for each WAN port or are having the traffic of both WAN ports routed through the same ISP.
3. Determine your network management approach
The RF30 is capable of remote management. However, this feature is not active by default. If you reset the device, remote administration must be enabled again. If you decide to manage your network remotely, be sure to change the default password to something more secure.
- Prepare to physically connect the RF30 to Cable or DSL modems and a computer.
Be sure to also review the SafetyWarnings located in the preface of this manual before working with your RF30.
3.3 Connecting Your Router
Connecting the RF30 is an easy three-step process:
- Connect the RF30 to your LAN by connecting Ethernet cables from your networked PCs to the LAN ports on the router. Connect the RF30 to your broadband Internet connection via router's WAN port.
- Plug the RF30 to an AC outlet with the included AC Power Adapter.
- Ensure that the Power and WAN LEDs are solidly lit, and that on any LAN port that has an Ethernet cable plugged in the LED is also solidly lit. The Status LED will remain solid as the device boots. Once the boot sequence is complete, the LED will shut off, indicating that the RF30 is ready.
If the router does not power on, please refer to Chapter 5: Troubleshooting for possible solutions.
3.4 Configuring PCs for TCP/IP Networking
Now that your RF30 is connected properly to your network, it's time to configure your networked PCs for TCP/IP networking.
In order for your networked PCs to communicate with your router, they must have the following characteristics:
- Have a properly installed and functioning Ethernet Network Interface Card (NIC).
- Be connected to the RF30, either directly or through an external repeater hub via an Ethernet cable.
- Have TCP/IP installed and configured with an IP address.
The IP address for each PC may be a fixed IP address or one that is obtained from a DHCP server. If using a fixed IP address, it is important to remember that it must be in the same subnet as the router. The default IP address of the RF30 is 192.168.1.254 with a subnet mask of 255.255.255.0. Using the default configuration, networked PCs must reside in the same subnet, and have an IP address in the range of 192.168.1.1 to 192.168.1.253. However, you'll find that the quickest and easiest way to configure the IP addresses for your PCs is to obtain the IP addresses automatically by using the router as a DHCP server.
If you are unable to access the web configuration interface, check to see if you have any software-based firewalls installed on your PCs, as they can cause problems accessing the 192.168.1.254 IP address of the RF30.
The following sections outline how to set up your PCs for TCP/IP networking. Refer to the applicable section for your PC's operating system.
3.4.1 Overview
Before you begin, make sure that the TCP/IP protocol and a functioning Ethernet network adapter is installed on each of your PCs.
The following operating systems already include the necessary software components you need to install TCP/IP on your PCs:

3.6 Information From Your ISP
3.6.1 Protocols
Before configuring this device, you have to check with your ISP (Internet Service Provider) to find out what kind of service is provided such as DHCP, Static IP, PPPoE, or PPTP. The following table outlines each of these protocols:
| DHCP | Configure this WAN interface to use DHCP client protocol to get an IP address from your ISP automatically. Your ISP provides an IP address to the router dynamically when logging in. |
| Static IP | Configure this WAN interface with a specific IP address. This IP address should be provided by your ISP. |
| PPPoE | PPPoE (PPP over Ethernet) is known as a dial-up DSL or cable service. It is designed to integrate the broadband services into the current widely deployed, easy-to-use, and low-cost dial-up-access networking infrastructure. |
| PPTP | If your ISP provides a PPTP connection, you can use the PPTP protocol to establish a connection to your ISP. |
| Big Pond | The Big Pond login for Telstra cable in Australia. |
If your account uses PPP over Ethernet (PPPoE), you will need to enter your login name and password when configuring your RF30. After the network and firewall are configured, the RF30 will login automatically, and you will no longer need to run the login program from your PC.
3.6.2 Configuration Information
If your ISP does not dynamically assign configuration information but instead uses fixed configurations, you will need the following basic information from your ISP:
- An IP address and subnet mask
- A gateway IP address
- One or more domain name server (DNS) IP addresses
Depending on your ISP, a host name and domain suffix may also be provided. If any of these items are dynamically supplied by the ISP, your RF30 will automatically acquire them.
If an ISP technician configured your computer or if you configured it using instructions provided by your ISP, you need to copy the configuration information from your PC's Network TCP/IP Properties window before reconfiguring your computer for use with the RF30. The following sections describe how you can obtain this information.
3.6.2.1 Windows
This section uses illustrations from Windows XP. However, other versions of Windows will follow a similar procedure. Have your Windows CD handy, as it may be required during the configuration process.
1. Select Start > Settings > Control Panel.
2. Double-click the Network icon.
3. In the Network Connections window, right-click Local Area Connection and select Properties.
- Select Internet Protocol (TCP/IP) and click Properties.
- If an IP address, subnet mask and a Default gateway are shown, write down the information. If no address is present, your account's IP address is dynamically assigned. Click the Obtain an IP address automatically radio button.
- If any DNS server addresses are shown, write them down. Click the Obtain DNS server address automatically radio button.
- Click OK to save your changes.

Proposal:
Secure Association (SA): SA is a method of establishing a security policy between two points. There are three methods of creating SA, each varying in degrees of security and speed of negotiation:
Main Mode: Uses the automated Internet Key Exchange (IKE) setup; most secure method with the highest level of security.
Aggressive Mode: Uses the automated Internet Key Exchange (IKE) setup; mid-level security. Speed is faster than Main mode.
Manual Key: Standard level of security. It is the fastest of the three methods.
Method: There are two methods of checking the authentication information, AH (Authentication Header) and ESP (Encapsulating Security Payload). Use ESP for greater security so that data will be encrypted and authenticated. AH data will be authenticated but not encrypted.
Encryption Protocol: Select the encryption method from the pull-down menu. There are several options: DES, 3DES, and AES (128, 192 and 256). 3DES and AES are more powerful but increase latency.
DES: Stands for Data Encryption Standard. It uses a 56-bit encryption method.
3DES: Stands for Triple Data Encryption Standard. It uses a 168-bit encryption method.
AES: Stands for Advanced Encryption Standard. You can use 128, 192 or 256 bits as encryption method.
Authentication Protocol: Authentication establishes data integrity and ensures it is not tampered with while in transit. There are two options: Message Digest 5 (MD5), and Secure Hash Algorithm (SHA1). While slower, SHA1 is more resistant to brute-force attacks than MD5.
MD5: A one-way hashing algorithm that produces a 128-bit hash.
SHA1: A one-way hashing algorithm that produces a 160-bit hash.
Perfect Forward Secure: Choose whether to enable PFS using Diffie-Hellman public-key cryptography to change encryption keys during the second phase of VPN negotiation. This function will provide better security, but extends the VPN negotiation time. Diffie-Hellman is a public-key cryptography protocol that allows two parties to establish a shared secret over the Internet.
Pre-shared Key: This is for the Internet Key Exchange (IKE) protocol. IKE is used to establish a shared security policy and authenticated keys for services (such as IPSec) that require a key. Before any IPSec traffic can be passed, each router must be able to verify the identity of its peer. This can be done by manually entering the pre-shared key into both sides (router or hosts).
IKE Life Time: Allows you to specify the timer interval for renegotiation of the IKE security association. The value is in seconds, eg. 28800 seconds = 8 hours.

4.4.8 Virtual Server
In TCP/IP and UDP networks, a port is a 16-bit number used to identify which application program (usually a server) incoming connections should be delivered to. Some ports have numbers that are pre-assigned to them by the Internet Assigned Numbers Authority (IANA), and these are referred to as "well-known ports". Servers follow the well-known port assignments so clients can locate them.
If you wish to run a server on your network that can be accessed from the WAN (i.e. from other machines on the Internet that are outside your local network), or any application that can accept incoming connections (e.g. peer-to-peer applications) and are using NAT (Network Address Translation), then you will usually need to configure your router to forward these incoming connection attempts using specific ports to the PC on your network running the application. You will also need to use port forwarding if you want to host an online game server. The reason for this is that when using NAT, your publicly accessible IP address will be used by and point to your router, which then needs to deliver all traffic to the private IP addresses used by your PCs. Please see the WAN Configuration section of this manual for more information on NAT.
The RF30 can also be configured as a virtual server so that remote users accessing services such as Web or FTP services via the public (WAN) IP address can be automatically redirected to local servers in the LAN network. Depending on the requested service (TCP/UDP port number), the device redirects the external service request to the appropriate server within the LAN network.
4.4.8.1 DMZ
The DMZ Host is a local computer exposed to the Internet. When setting a particular internal IP address as the DMZ Host, all incoming packets will be checked by the Firewall and NAT algorithms then passed to the DMZ host, when a packet received does not use a port number used by any other Virtual Server entries.
Caution: Such Local computer exposure to the Internet may face a variety of security risks.
Enable DMZ function:
Enable: Activates your router's DMZ function.
Disable: Default setting. Enables the DMZ function.
DMZ IP Address: Give a static IP address to the DMZ Host when the Enable radio button is selected. Be aware this IP will be exposed to the WAN/Internet.
Select the Apply button to apply your changes.
4.4.8.2 Port Forwarding Table
Because NAT can act as a "natural" Internet firewall, your router protects your network from being accessed by outside users, as all incoming connection attempts will point to your router unless you specifically create Virtual Server entries to forward those ports to a PC on your network.
When your router needs to allow outside users to access internal servers, e.g. a web server, FTP server, Email server or game server, the router can act as a "virtual server". You can set up a local server with a specific port number for the service to use, e.g. web/HTTP (port 80), FTP (port 21), Telnet (port 23), SMTP (port 25), or POP3 (port 110). When an incoming access request is received, it will be forwarded to the corresponding internal server.
Click Create to add a new port forwarding rule. There are two port forwarding modes: Port Range Mapping and Port Redirection.
4.4.8.2.1 Port Range Mapping
This function allows any incoming data addressed to a range of service port numbers (from the Internet/WAN Port) to be re-directed to a particular LAN private/internal IP address. This option gives you the ability to handle applications that use more than one port such as games and audio/video conferencing.
Forwarding Mode: Click the Port Range Mapping radio button to change to Port Range Mapping mode.
Internal IP Address: Enter the LAN server/host IP address that the service request from the Internet will be sent to.
NOTE: You need to give your LAN server/host a static IP address for the Virtual Server to work properly.
External Port Range: Enter the port number of the service that will be sent to the Internal IP address.
Click Apply to save your changes.
4.4.8.2.2 Port Redirect
This function allows any incoming data addressed to a specific service port number (from the Internet/WAN Port) to be redirected to an internal IP address.
Forwarding Mode: Click the Port Redirector radio button to change to Port Redirector mode.
Internal IP Address: Enter the LAN server/host IP address that the service request from the Internet will be sent to.
NOTE: You need to give your LAN server/host a static IP address for the Virtual Server to work properly.
External Port: Enter the port number of the service that will be sent to the Internal IP address.
Internal Port: Enter a new port number for the service that will be sent to the Internal IP address.
Click Apply to save your changes.
Using port forwarding does have security implications, as outside users will be able to connect to PCs on your network. For this reason, using specific Virtual Server entries just for the ports your application requires, instead of using DMZ is recommended.
4.4.9 Advanced
Configuration options within the Advanced section are for users who wish to take advantage of the more advanced features of the RF30. Users who do not understand the features should not attempt to reconfigure their router, unless advised to do so by support staff.
There are three items within the Advanced section: Static Route, Dynamic DNS and Device Management.
4.4.9.1 Static Route
The static route settings enable the router to route IP packets to another network ( subnet). The routing table stores the routing information so the router knows where to redirect the IP packets.
Click on Static Route and then click Create to add a routing table.
Destination: This is the destination subnet IP address.
Netmask: This is the subnet mask of the destination IP addresses based on above destination subnet IP.
Gateway: This is the gateway IP address to which packets are to be forwarded.
Interface: Select the interface through which packets are to be forwarded.
Cost: This is the same meaning as Hop.
Click Apply to save your changes.
4.4.9.2 Dynamic DNS
The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users whose ISP does not assign them a static IP address to use a domain name. This is especially useful when hosting servers via your WAN connection, so that anyone wishing to connect to you may use your domain name, rather than having to use a dynamic IP address that changes periodically. This dynamic IP address is the WAN1/WAN2 IP address of the router, which is assigned to you by your ISP. Click Edit in the Dynamic DNS Settings Table to set related parameters for a specific interface.
You will first need to register and establish an account with the Dynamic DNS provider using their website,
Example: DYNDNS
http://www.dyndns.org/
(RF30 supports several Dynamic DNS providers, such as www.dyndns.org, www.orgdns.org, www.dhs.org, www.dyns.cx, www.3domain.hk, www.dyndns.org, www.3322.org)
Dynamic DNS:
Disable: Check to disable the Dynamic DNS function.
Enable: Check to enable the Dynamic DNS function. The following fields will be activated and required:
Dynamic DNS Server: Select the DDNS service you have established an account with.
Wildcard: Select this check box to enable the DYNDNS Wildcard.
Domain Name: Enter your registered domain name for this service.
Username: Enter your registered user name for this service.
Password: Enter your registered password for this service.
Click Apply to save your changes.
4.4.9.3 Device Management
The Device Management Advanced Configuration settings allow you to control your router's security options and device monitoring features.
Device Name
Name: Enter a name for this device.
Web Server Settings
HTTP Port: This is the port number the router's embedded web server (for web-based configuration) will use. The default value is the standard HTTP port, 80. Users may specify an alternative if, for example, they are running a web server on a PC within their LAN.
Management IP Address: You may specify an IP address allowed to logon and access the router's web server. Setting the IP address to 0.0.0.0 will disable IP address restrictions, allowing users to login from any IP address.
Expire to auto-login: Specify a time frame for the system to auto-login the user's configuration session.
Example: User A changes HTTP port number to 100, specifies their own IP address of 192.168.1.100 and sets the logout time to be 100 seconds. The router will only allow User A access from the IP address 192.168.1.100 to logon to the Web GUI by typing: http://192.168.1.254:100 in their web browser. After 100 seconds, the device will automatically logout User A.
4.5 Save Configuration To Flash
After changing the router's configuration settings, you must save all of the configuration parameters to flash memory to avoid them being lost after turning off or resetting your router. Click Apply to write your new configuration to flash memory.
4.6Logout
To exit the router's web interface, click Logout. Please ensure that you have saved your configuration settings before you logout.
Be aware that the router is restricted to only one PC accessing the web configuration interface at a time. Once a PC has logged into the web interface, other PCs cannot gain access until the current PC has logged out. If the previous PC forgets to logout, the second PC can access the page after a user-defined period (5 minutes by default). You can modify this value using the Advanced > Device Management section of the Web Configuration Interface. Please see the Advanced section of this manual for more information.
Chapter 5: Troubleshooting
5.1 Basic Functionality
This section deals with issues regarding your RF30's basic functions.
5.1.1 Router Won't Turn On
If the Power and other LEDs fail to light when your RF30 is turned on:
- Make sure that the power cord is properly connected to your firewall and that the power supply adapter is properly connected to a functioning power outlet.
- Check that you are using the 12VDC power adapter supplied by Cometlabs for this product.
If the error persists, you may have a hardware problem, and should contact technical support.
5.1.2 LEDs Never Turn Off
When your RF30 is turned on, the LEDs turn on for about 10 seconds and then turn off. If all the LEDs stay on, there may be a hardware problem.
If all LEDs are still on one minute after powering up:
- Cycle the power to see if the router recovers.
- Clear the configuration to factory defaults.
If the error persists, you may have a hardware problem, and should contact technical support.
5.1.3 LAN or Internet Port Not On
If either the LAN LEDs or Internet LED do not light when the Ethernet connection is made, check the following:
- Make sure each Ethernet cable connection is secure at the firewall and at the hub or workstation.
- Make sure that power is turned on to the connected hub or workstation.
- Be sure you are using the correct cable. When connecting the firewall's Internet port to a cable or DSL modem, use the cable that was supplied with the cable or DSL modem. This cable could be a standard straight-through Ethernet cable or an Ethernet crossover cable.

5.3 WAN Interface
If you are having problems with the WAN Interface, refer to the tips below.
5.3.1 Can't Get WAN IP Address from the ISP
If the WAN IP address cannot be obtained from the ISP:
- If you are using PPPoE or PPTP encapsulation, you will need a user name and password. Ensure that you have entered the correct Service Type, User Name, and Password. Note that user names and passwords are case-sensitive.
- If your ISP requires MAC address authentication, clone the MAC address from your PC on the LAN as the RF30's WAN MAC address.
- If your ISP requires host name authentication, configure your PC's name as the RF30's system name.
5.4 ISP Connection
Unless you have been assigned a static IP address by your ISP, your RF30 will need to request an IP address from the ISP in order to access the Internet. If your RF30 is unable to access the Internet, first determine if your router is able to obtain a WAN IP address from the ISP.
To check the WAN IP address:
- Open your browser and choose an external site (i.e. www.Cometlabs.com).
- Access the Web Configuration Interface by entering your router's IP address (default is 192.168.1.254).
- The WAN IP Status is displayed on the first page.
- Check to see that the WAN port is properly connected to the ISP. If a Connected by (±bx) where (±bx) is your connection method is not shown, your router has not successfully obtained an IP address from your ISP.
If an IP address cannot be obtained:
- Turn off the power to your cable or DSL modem.
- Turn off the power to your RF30.
- Wait five minutes and power on your cable or DSL modem.
- When the modem has finished synchronizing with the ISP (generally shown by LEDs on the modem), turn on the power to your router.
If an IP address still cannot be obtained:
- Your ISP may require a login program. Consult your ISP whether they require PPPoE or some other type of login.
- If your ISP requires a login, check to see that your User Name and Password are entered correctly.
- Your ISP may check for your PC's host name. Assign the PC Host Name of your ISP account as your PC's host name on the router.
- Your ISP may check for your PCs MAC address. Either inform your ISP that you have purchased a new network device or ask them to use your router's MAC address, or configure your router to spoof your PC's MAC address.
If an IP address can be obtained, but your PC cannot load any web pages from the Internet:
- Your PC may not recognize DNS server addresses. Configure your PC manually with DNS addresses.
- Your PC may not have the router correctly configured as its TCP/IP gateway.
5.5 Problems with Date and Time
If the date and time is not being displayed correctly, be sure to set it for your RF30 via the Web Configuration Interface. Both date and time can be found under Configuration > System > Time Zone.
5.6 Restoring Factory Defaults
You can restore your RF30 to its factory settings by holding the Reset button on the back of your router until the Status LED begins to blink. This will reset your router to its default settings.

Appendix D: Network, Routing, and Firewall Basics
D.1 Network Basics
D.1.1 IP Addresses
With the number of TCP/IP networks interconnected across the globe, ensuring that transmitted data reaches the correct destination requires each computer on the Internet has a unique identifier. This identifier is known as the IP address. The Internet Protocol (IP) uses a 32-bit address structure, and the address is usually written in dot notation.
A typical IP address looks like this:
198.25.12.8
The 32 bits of the address are subdivided into two parts. The first part of the address identifies the network, while the second part identifies the host node or station on the network. How the address is divided depends on the address range and the application.
The five standard IP address classes each have different methods to determine the network and host sections of the address, which makes multiple hosts on a network possible. TCP/IP software identifies each address class by reading a unique bit pattern that precedes each address type. Once the address class has been recognized, the software can then correctly determine the addresses' host section. With this structure, IP addresses can uniquely identify each network and node.
D.1.1.1 Net mask
With each address class, the size of the two subdivided parts (network address and host address) is implied by the class. A net mask associated with an IP address can also express this partitioning. A net mask 32-bit quantity yields the network address when combined with an IP address. As an example, the net masks for Class A, B, and C are 255.0.0.0, 255.255.0.0, and 255.255.255.0 respectively.
Instead of dotted-decimal notation, the net mask can also be written in terms of the number of ones from the left. This number is added to the IP address, following a backward slash (/). For example, a typical Class C address could be written as 192.168.234.245/24, which means that the net mask is 24 ones followed by 8 zeros. (11111111 11111111 11111111 00000000).
D.1.1.2 Subnet Addressing
Subnet addressing enables the split of one IP network address into multiple physical networks. These smaller networks are called subnetworks, and these subnetworks can make efficient use of each address when compared to needing a different network number at each end of a routed link. This technique is especially useful in smaller network environments, such as small office LANs.
A Class B address provides 16 bits of node numbers, which enable 65,536 nodes. Since most organizations don't require such a large number of nodes, the free bits can be reassigned with subnet addressing.
Multiple Class C addresses can be made from a Class B address. For example, the IP address of 172.20.0.0 allows eight extra bits to use as a subnet address, since node addresses are limited to a maximum of 255. The IP address of 172.20.52.212 would be read as IP network address 172.20, subnet number 52, and node number 212.
Besides extending the number of available addresses, this technique also allows a network manager to design an address scheme for the network by using different subnets. This can be useful when trying to distinguish other geographical locations in the network or other departments in the organization.
D.1.1.3 Private IP Addresses
When isolated from the Internet, the hosts on your local network may be assigned IP addresses with no conflicts. However, the Internet Assigned Numbers Authority (IANA) has reserved several blocks of IP addresses for private networks. These include:
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.16.255.255
192.168.0.0 - 192.168.255.255
When assigning IP addresses to your private network, be sure to use IP addresses from these ranges.
D.1.2 Network Address Translation (NAT)
Traditionally, multiple PCs that needed simultaneous Internet access also required a range of IP addresses from the Internet Service Provider (ISP). Not only was this method very costly, but the number of available IP addresses for PCs is limited. Instead, the RF30 uses a type of address sharing called Network Address Translation to grant Internet access to several PCs on the same network through the same Internet account. This method translates internal IP addresses to a single address that is unique on the Internet. This unique address can either be fixed or dynamic, depending on the type of Internet account, and the internal LAN IP addresses may also be either private or registered addresses.
NAT also offers firewall-like protection to your network, since internal LAN addresses are shielded from the public Internet. All incoming traffic to the public IP address is handled by the router, which means added security for your network from intruders. If a particular PC on your LAN requires access from outside PCs, you can use port forwarding to accomplish this. For information on how to configure port forwarding on the RF30, refer to the Virtual Server section of Chapter 4: Router Configuration.
D.1.3 Dynamic Host Configuration Protocol (DHCP)
If the PCs on a LAN require access to the Internet, each PC must be configured with an IP address, a gateway address, and one or more DNS server addresses. Rather than configuring each PC manually, you can instead configure a network device to act as a Dynamic Host Configuration Protocol (DHCP) server. PCs on the network can automatically obtain IP addresses from a list of addresses stored on the DHCP server. In addition, other information such as gateway and DNS address can also be assigned with a DHCP server. When connecting to the ISP, the RF30 also functions as a DHCP client. The RF30 can automatically obtain an IP address, subnet mask, gateway address, and DNS server addresses if the ISP assigns this information via DHCP.
D.2 RouterBasics
D.2.1 What is a Router?
A router is a device that forwards data packets along networks. A router is connected to at least two networks. Usually, this is a LAN and a WAN that is connected to an ISP network. Routers are located at gateways, the places where two or more networks connect. Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols to communicate with each other and configure the best route between any two hosts.
Routers can vary in performance and scale, the types of physical WAN connection they support, and the number of routing protocols supported. The RF30 offers a convenient and powerful way for small-to-medium businesses to connect their networks.
D.2.2 Why use a Router?
While large bandwidth can easily and inexpensively be provided in a LAN, having high bandwidth between a LAN and the Internet can be prohibitively expensive. Because of this, Internet access is usually done through a slower WAN link, such as a cable or DSL modem. To efficiently use this slower connection, a router acts as a mechanism for selecting and transmitting data meant for the Internet. By using a router, organizations can enjoy relatively inexpensive Internet access, while maintaining a high-speed local area network.
D.2.3 Routing Information Protocol (RIP)
Routing Information Protocol (RIP) is an interior gateway protocol that specifies how routers exchange routing table information. Routers periodically update each other with RIP, changing their routing tables when necessary.
The RF30 supports the RIP protocol. RIP also supports subnet and multicast protocols. RIP is not required for most home applications.
D.3 Firewall Basics
D.3.1 What is a Firewall?
Firewalls prevent unauthorized Internet users from accessing private networks connected to the Internet. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria. With the functionality of a NAT router, the firewall adds features that deal with outside Internet intrusion and attacks. When an attack or intrusion is detected, the firewall can be configured to log the intrusion attempt, and can also notify the administrator of the incident. With this information, the administrator can work with the ISP to take action against the hacker. Against some types of attacks, the firewall can discard intruder packets, thereby fending off the hacker from the private network.
D.3.1.1 Stateful Packet Inspection
The RF30 uses Stateful Packet Inspection (SPI) to protect your network from intrusions and attacks. Unlike less sophisticated Internet sharing routers, SPI ensures secure firewall filtering by intercepting incoming packets at the network layer, and analyzing them for state-related information that is associated with all network connections. User-level applications such as Web browsers and FTP can make complex network traffic patterns, which the RF30 analyzes by looking at groups of connection states.
All state information is stored in a central cache. Traffic passing through the firewall is analyzed against these states, and then is either allowed to pass through or rejected.
D.3.1.2 Denial of Service (DoS) Attack
A hacker may be able to prevent your network from operating or communicating by launching a Denial of Service (DoS) attack. The method used for such an attack can be as simple as merely flooding your site with more requests than it can handle. A more sophisticated attack may attempt to exploit some weakness in the operating system used by your router or gateway. Some operating systems can be disrupted by simply sending a packet with incorrect length information.
D.3.2 Why Use a Firewall?
With a LAN connected to the Internet through a router, there is a chance for hackers to access or disrupt your network. A simple NAT router provides a basic level of protection by shielding your network from the outside Internet. Still, there are ways for more dedicated hackers to either obtain information about your network or disrupt your network's Internet access. Your RF30 provides an extra level of protection from such attacks with its built-in firewall.
Appendix E: Virtual Private Networking
E.1 What is a VPN?
A Virtual Private Network (VPN) is a shared network where private data is segmented from other traffic so that only the intended recipient has access. It allows organizations to securely transmit data over a public medium like the Internet. VPNs utilize tunnels, which allow data to be safely delivered to the intended recipient.
Because private networks lack data security, IPSec-based VPNs employ encryption technologies that protect a private network from data theft or tampering. These private networks can be implemented over any type of IP network, which allows for excellent flexibility.
E.1.1 VPN Applications
VPNs are traditionally used three ways:
- Extranets: Extranets are secure connections between two or more organizations. IPSec-based VPNs are ideal for extranet connections, as they can be quickly and inexpensively installed. Extranets are often used to securely share a company's information with suppliers, vendors, customers, or other businesses.
- Intranets: Intranets are private networks that connect an organization's locations together. These locations range from a headquarters, to branch offices, to a remote employee's home. Intranets are often used for email and for sharing applications and files. A firewall protects Intranets from unauthorized access.
- Remote Access: Remote access enables mobile workers to access email and business applications. Remote access VPNs greatly reduce expenses by enabling mobile workers to dial a local Internet connection and then set up a secure IPSec-based VPN communications to their organization.
E.2 What is IPSec?
Internet Protocol Security (IPSec) is a set of protocols and algorithms that provide data authentication, integrity, and confidentiality as data is transferred across IP networks. IPSec provides data security at the IP packet level, and protects against possible security risks by protecting data. IPSec is widely used to establish VPNs.
There are three major functions of IPSec:
- Confidentiality: Conceals data through encryption.
- Integrity: Ensures that contents did not change in transit.
- Authentication: Verifies that packets received are actually from the claimed sender.
E.2.1 IPSec Security Components
IPSec contains three major components:
- Authentication Header (AH): Provides authentication and integrity.
- Encapsulating Security Payload (ESP): Provides confidentiality, authentication, and integrity.
- Internet Key Exchange (IKE): Provides key management and Security Association (SA) management.
These components are discussed below.
E.2.1.1 Authentication Header (AH)
The Authentication Header (AH) is a protocol that provides authentication and integrity, protecting data from tampering. It provides authentication of either all or part of the contents of a datum through the addition of a header that is calculated based on the values in the datum.
The AH can also protect packets from unauthorized re-transmission with anti-replay functionality. The presence of the AH header allows us to verify the integrity of the message, but doesn't encrypt it. Thus, AH provides authentication but not privacy. ESP protects data confidentiality. Both AH and ESP can be used together for added protection.
A typical AH packet looks like this:
| Next Header | Payload Length | Reserved |
| SPI | ||
| Sequence Number | ||
| Authentication Data | ||
E.2.1.2 Encapsulating Security Payload (ESP)
Encapsulating Security Payload (ESP) provides privacy for data through encryption. An encryption algorithm combines the data with a key to encrypt it. It then repackages the data using a special format, and transmits it to the destination. The receiver then decrypts the data using the same algorithm. ESP is usually used with AH to provide added data security.
ESP divides its fields into three components...
ESP Header: Placed before encrypted data, the ESP Header contains the SPI and Sequence Number. Its placement depends on whether ESP is used in transport mode or tunnel mode.
ESP Trailer: Placed after the encrypted data, the ESP Trailer contains padding that is used to align the encrypted data.
ESP Authentication Data: This contains an Integrity Check Value (ICV) for when ESP's optional authentication feature is used.
ESP provides authentication, integrity, and confidentiality, which provides data content protection, and protects against data tampering.
A typical ESP packet looks like this:
| SPI | ||
| Sequence Number | ||
| IV | ||
| Data | ||
| Pad | Pad | Next |
| Authentication Data | ||
E.2.1.3 Security Associations (SA)
Security Associations are a one-way relationships between sender and receiver that specify IPSec-related parameters. They provide data protection by using the defined IPSec protocols, and allow organizations to control according to the security policy in effect, which resources may communicate securely.
SA is identified by 3 parameters:
- Security Parameters Index (SPI), a locally unique value
- Destination IP Address
- Security Protocol: (AH or ESP, but not both)
There are several other parameters associated with an SA that are stored in a Security Association database.
E.2.2 IPSec Modes
To exchange data between different types of VPNs, IPSec provides two major modes:
- Tunnel Mode
This mode is used for host-to-host security. Protection extends to the payload of IP data, and the IP addresses of the hosts must be public IP addresses.
| IP | AH/E | IP | TC | Dat |
Transport Mode
- This mode is used to provide data security between two networks. It provides protection for the entire IP packet and is sent by adding an outer IP header corresponding to the two tunnel end-points. Since tunnel mode hides the original IP header, it provides security of the networks with private IP address space.
| IP | AH/E | TC | Dat |
E.2.3 Tunnel Mode AH
AH is typically applied to a data packet in the following manner:
Original Packet
E.2.4 Tunnel Mode ESP
Here is an example of a packet with ESP applied:
E.2.5 Internet Key Exchange (IKE)
Before either AH or ESP can be used, it is necessary for the two communication devices to exchange a secret key that the security protocols themselves will use. To do this, IPSec uses Internet Key Exchange (IKE) as a primary support protocol. IKE facilitates and automates the SA setup, and exchanges keys between parties transferring data. Using keys ensures that only the sender and receiver of a message can access it. These keys need to be re-created or refreshed frequently so that the parties can communicate securely with each other. Refreshing keys on a regular basis ensures data confidentiality.
There are two phases to this process. Phase I deals with the negotiation and management of IKE and IPSec parameters. This phase can be carried out in either one of two modes: Main Mode or Aggressive Mode. Main mode utilizes three message pairs that negotiate IKE parameters, establish a shared secret and derive session keys, and exchange and provide identities, retroactively authenticating the information sent. This method is very secure, but when using the pre-shared key method for authentication, it is possible to use IDs other than the packets's IP addresses. Aggressive mode reduces this process to three messages, but parameter negotiation is limited, identity protection is lacking except when using public key encryption, and is more vulnerable to Denial of Service attacks.
Phase II, known as Quick Mode, establishes symmetrical IPSec Security Associations for both AH and ESP. It does this by negotiating IPSec parameters, exchange nonces to derive session keys from the IKE shared secret, exchange DH values to
generate a new key, and identify which traffic this SA bundle will protect using selectors (IDi and IDr payloads).
The following is an illustration on how data is handled with IKE:

Appendix G: Bandwidth Management with QoS
G.1 Overview
In a home or office environment, users constantly have to transmit data to and from the Internet. When too many are accessing the Internet at the same time, service can slow to a crawl, causing service interruptions and general frustration. Quality of Service (QoS) is one of the ways the RF30 can optimize the use of bandwidth, ensuring a smooth and responsive Internet connection for all users.
G.2 What is Quality of Service?
QoS is a feature that prioritizes and guarantees bandwidth to achieve optimal service performance. QoS can maximize the use of available network bandwidth by prioritizing time-sensitive traffic to avoid latencies and delays. By ensuring that time-sensitive applications such as VoIP and streaming video get priority access to bandwidth, users in both home and office environments can enjoy smooth and responsive data transmission no matter which applications they are running.
If you've ever experienced slow Internet speeds due to other network users using bandwidth-consuming applications like P2P, you'll understand why QoS is such a breakthrough for home users and office users. Cometlabs makes itself unique by integrating QoS in its routers for both inbound and outbound traffic.
QoS helps users manage bandwidth and effectively prioritize data traffic. It gives you full control over the traffic of any type of data. Employed on DiffServ (Differentiated Services) architecture, data traffic is given priority by the router; ensuring latency-sensitive applications like voice and mission-critical data such as VPN move through the router at lightning speeds, even under heavy load. You can throttle the speed of different types of data passing through the router, limit the speed of unimportant or bandwidth-consuming applications, and even distribute the bandwidth for different
groups of users at home or in the office. QoS keeps your Internet connection smooth and responsive.
G.3 How Does QoS Work?
QoS employs three different methods for optimizing bandwidth:
-Prioritization: Assigns different priority levels for different applications, prioritizing traffic. High, Normal and Low priority settings.
-Outbound and Inbound IP Throttling: Controls network traffic and allows you to limit the speed of each application.
- DiffServ Technology: Manages priority queues and DSCP tagging through the Internet backbone. Manages traffic among Ethernet, wireless, and ADSL interfaces.
G.4 Who Needs QoS?
QoS is ideal for home and office users who need to use a variety of real-time applications like VoIP, on-line games, P2P, video streaming, and FTP simultaneously. With QoS, you can optimize your bandwidth to accommodate several of these applications without experiencing latency or service interruptions.
G.4.1 Home Users
Low latency is everything for gamers. Most home users feel frustrated when trying to play an online game over a shared ADSL connection. Unfortunately, most routers have no way of determining the importance of the packet at any given time. All the traffic is treated equally, so a packet containing an "urgent" command may be delayed. QoS gives you the ability to control the bandwidth. Using IP Throttling, bandwidth limits can be enforced on a particular application or any system within the LAN. Prioritization specifies which packets have priority and should not be delayed, and which packets have lower priority and should be moved to the end of the upload queue.
Suppose there are four students sharing a three-floor house with one single broadband connection. Tom, a college freshman, is playing the online game with his group members, while Mary, a sophomore student, is talking to her net pal via Skype. Meanwhile, Jacky is downloading a movie file by using the P2P application program. Sophia, however, is just trying to log on to the website to send her photos to her family. As a result, the net speed slows to a crawl and affects everyone sharing the
Internet connection. QoS is designed for managing traffic flow and bandwidth to solve this problem. You can first classify different applications (online games, FTP, Skype, email) as shown in the table below. Then, you can manage and prioritize the flow of bandwidth at different levels (e.g. 30% for games, 20% for downloads, 10% for email, 20% for FTP, and 35% for others). QoS can be used to identify different applications and assign priority to enable a smooth and responsive broadband connection.
| Application | Data Ratio (%) | Priority |
| On-line games | 30% | High |
| Skype | 5% | High |
| 10% | High | |
| FTP | 20% | Upload (High), Download (Normal) |
| Other | 35% |
G.4.2 Office Users
QoS is also ideal for small businesses using an office server as a web server. With QoS control, web pages served to your customers can be given top priority and delivered first so that it will not be impeded by email and office web browsing.
Here is a good example of how QoS can work in an office environment. A CEO is holding a videoconference with international clients in the meeting room. However, the streaming video and voice frequently lag. Sales people are talking to international agencies via VoIP phone, while sending orders via email to vendors for production. However, some staff are downloading MP3 music files, large-size photos and watching video streaming online. Consequently, the Internet connection slows down. This is why business users need QoS to manage data traffic. With QoS, the network administrator can define and classify important packets; specify a minimum guaranteed rate for each application, and ensure that important packets have priority to ensure a good quality of broadband connection for the entire organization.
| Application | Data Ratio (%) | Priority |
| Videoconferencing | 30% | High |
| VoIP | 20% | High |
| 10% | High | |
| FTP | 10% | Upload (High), Download (Normal) |
| Other | 30% | MP3 (Low), MSN (Normal) |
