Product Overview

Features

PPP (Point-to-Point Protocol) Security

The DSL-500B ADSL Router supports PAP (Password Authentication Protocol), CHAP (Challenge Handshake

Authentication Protocol), and MS-CHAP for Point-to-Point Protocol connections.

DHCP Support

Dynamic Host Configuration Protocol automatically and dynamically assigns all LAN IP settings to each host on your network. This eliminates the need to reconfigure every host whenever changes in network topology occur.

Network Address Translation (NAT)

For small office environments, the DSL-500B allows multiple users on LAN to access the Internet concurrently through a single Internet account. This provides Internet access to everyone in the office for the price of a single user. NAT improves network security in effect by hiding the private network behind one global and visible IP address. NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection.

TCP/IP (Transfer Control Protocol/Internet Protocol)

The DSL-500B supports TCP/IP protocol, the standard language used for Internet access. It is compatible with access servers manufactured by major vendors.

RIP-1/RIP-2 (Routing Information Protocol)

The DSL-500B supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions lets the Router to communicate with all RIP enabled devices.

Static Routing

This allows you to select a data path to a particular network destination that will remain in the routing table and never “age out”. If you wish to define a specific route that will always be used for data traffic from your LAN to a specific destination within your LAN (for example to another router or a server) or outside your network (to an ISP defined default gateway for instance).


Product Overview

Default Routing

This allows you to choose a default path for incoming data packets for which the destination address is unknown.

This is particularly useful when/if the Router functions as the sole connection to the Internet.

ATM (Asynchronous Transfer Mode)

The DSL-500B supports Bridged Ethernet over ATM (RFC1483), IP over ATM (RFC1577), and PPP over

ATM (RFC 2364).

Precise ATM Traffic Shaping

Traffic shaping is a method of controlling the flow rate of ATM data cells. This function helps to establish the Quality of Service for ATM data transfer.

G.hs (Auto-handshake)

This allows the Router to automatically choose either the G.lite or G.dmt ADSL connection standards.

High Performance

The Router provides up to 8 Mbps downstream bit rate using the G.dmt standard.

Full Network Management

The DSL-500B incorporates SNMP (Simple Network Management Protocol) support for web-based management and text-based network management.

Telnet Connection

Telnet enables a network manager to access the Router’s management software remotely.

Easy Installation

The DSL-500B uses a web-based graphical user interface program for convenient management access and easy set up. Any common web browser software can be used to manage the Router.

Overview

This section will walk you through the installation process. Placement of the ADSL Router is very important. Do not place the Router in an enclosed area such as a closet, cabinet, or in the attic or garage. Place the ADSL Router in a location where it can be easily connected to Ethernet devices, the telephone line as well as to a power source.

Installation Notes

Please read and make sure you understand all the prerequisites for proper installation of your new Router.

Have all the necessary information and equipment on hand before beginning the installation.

In order to establish a connection to the Internet it will be necessary to provide information to the Router that will be stored in its memory. For some users, only their account information (Username and Password) is required. For others, various parameters that control and define the Internet connection will be required. You can print out the two pages below and use the tables to list this information. This way you have a hard copy of all the information needed to setup the Router. If it is necessary to reconfigure the device, all the necessary information can be easily accessed. Be sure to keep this information safe and private.

Low Pass Filters

Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to avoid mutual interference. A low pass filter device can be installed for each telephone that shares the line with the ADSL line. These filters are easy to install passive devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more information about the use of low pass filters with your installation.

Operating Systems

The DSL-500B uses an HTML-based web interface for setup and management. The web configuration manager may be accessed using any operating system capable of running web browser software, including Windows 98 SE,

Windows ME, Windows 2000, Windows XP, and Windows Vista.


Installation

Web Browser

Any common web browser can be used to configure the Router using the web configuration management software.

The program is designed to work best with more recently released browsers such as Opera, Microsoft Internet

Explorer® version 6.0, Netscape Navigator® version 6.2.3, or later versions. The web browser must have JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not been disabled by other software (such as virus protection or web user security packages) that may be running on your computer.

Ethernet Port (NIC Adapter)

Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This connection is an Ethernet connection and therefore requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the installation instructions that come with the Ethernet NIC adapter.

Additional Software

It may be necessary to install software on your computer that enables the computer to access the Internet.

Additional software must be installed if you are using the device as a simple bridge. For a bridged connection, the information needed to make and maintain the Internet connection is stored on another computer or gateway device, not in the Router itself.

If your ADSL service is delivered through a PPPoE or PPPoA connection, the information needed to establish and maintain the Internet connection can be stored in the Router. In this case, it is not necessary to install software on your computer. It may, however, be necessary to change some settings in the device, including account information used to identify and verify the connection.

All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must reside in a TCP/IP enabled device on the LAN side of the bridge, such as a PC, a server, a gateway device such as a router or similar firewall hardware. The IP address can be assigned in a number of ways. Your network service provider will give you instructions about any additional connection software or network configuration that may be required.


Installation

Information Required from ADSL Service Provider

Username

This is the Username used to log on to your ADSL service provider’s network. Your ADSL service provider uses this to identify your account.

Password

This is the Password used, in conjunction with the Username above, to log on to your ADSL service provider’s network. This is used to verify the identity of your account.

WAN Setting / Connection Type

These settings describe the method your ADSL service provider uses to transport data between the Internet and your computer. Most users will use the default settings. You may need to specify one of the following WAN Setting and Connection Type configuration (Connection Type settings listed in parenthesis):

PPPoE/PPoA (PPPoE LLC, PPPoA LLC or PPPoA VC-Mux)

Dynamic IP Address (1483 Bridged IP LLC, 1483 Bridged IP VC-Mux)

Static IP Address (1483 Bridged IP LLC, 1483 Bridged IP VC-Mux, 1483 Routed IP LLC (IPoA) or 1483 Routed

IP VC-Mux)

Bridge Mode (1483 Bridged IP LLC or 1483 Bridged IP VC Mux)

Modulation Type

ADSL uses various standardized modulation techniques to transmit data over the allotted signal frequencies.

Some users may need to change the type of modulation used for their service. The default DSL modulation (Auto

Synch-Up) used for the Router automatically detects all types of ADSL, ADSL2, and ADSL2+ modulation.

Security Protocol

This is the method your ADSL service provider will use to verify your Username and Password when you log on to their network. Your Router supports the PAP and CHAP protocols.


Installation

VPI

Most users will not be required to change this setting. The Virtual Path Identifier (VPI) is used in conjunction with the Virtual Channel Identifier (VCI) to identify the data path between your ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtual connections, you will need to configure the VPI and

VCI as instructed by your ADSL service provider for the additional connections. This setting can be changed in the

WAN Settings window of the web management interface.

VCI

Most users will not be required to change this setting. The Virtual Channel Identifier (VCI) used in conjunction with the VPI to identify the data path between your ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtual connections, you will need to configure the VPI and VCI as instructed by your ADSL service provider for the additional connections. This setting can be changed in the WAN Settings window of the web management interface.


Installation

Information You Will Need About the DSL-500B

Username

This is the Username needed to access the Router’s management interface. When you attempt to connect to the device through a web browser you will be prompted to enter this Username. The default Username for the Router is

admin. This name cannot be changed.

Password

This is the Password you will be prompted to enter when you access the Router’s management interface. The default Password is admin. For security purposes, ensure to change this password.

LAN IP Addresses for the DSL-500B

This is the IP address you will enter into the Address field of your web browser to access the Router’s configuration graphical user interface (GUI) using a web browser. The default IP address is 192.168.254.254. This may be changed to suit any IP address scheme the user desires. This address will be the base IP address used for DHCP service on the LAN when DHCP is enabled.

LAN Subnet Mask for the DSL-500B

This is the subnet mask used by the DSL-500B, and will be used throughout your LAN. The default subnet mask is

255.255.255.0. This can be changed later.


Installation

Information You Will Need About Your LAN or Computer

Ethernet Network Interface Card (NIC)

If your computer has an Ethernet NIC, you can connect the DSL-500B to this Ethernet port using an Ethernet cable.

You can also use the Ethernet port on the DSL-500B to connect to other computer or Ethernet device.

DHCP Client Status

Your DSL-500B ADSL Router is configured to be a DHCP server, by default. This means that it can assign an IP address, subnet mask, and a default gateway address to computers on your LAN. The default range of IP addresses the DSL-500B will assign are from 192.168.254.1 to 192.168.254.253. Your computer (or computers) needs to be configured to obtain an IP address automatically (that is, they must be configured as DHCP clients.)

It is recommended that you collect and record this information here, or in some other secure place, in case you have to re-configure your ADSL connection in the future.

Once you have the above information, you are ready to setup and configure your DSL-500B ADSL Router.


Installation

Device Installation

The DSL-500B maintains two separate interfaces: ADSL (WAN) and an Ethernet (LAN). Place the Router in a location where it can be easily connected to Ethernet devices, the telephone line, and a power source.

The Router can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the front of the device, should you ever need to view them for troubleshooting.

Power On

The Router must be used with the power adapter included with the device.

1. Connect the power adapter to the Power receptacle (12V DC, 1A) on the rear panel of the Router and plug the other end of the power adapter to a wall outlet or power strip.

2. Push the On/Off button on the rear panel of the Router to turn the power on.

3. The Power LED on the front panel will turn bright green to indicate the device is powered on.

4. If the Ethernet port is connected to a working device, check the LAN LED indicator to make sure the connection is valid. The Router will attempt to establish the ADSL connection, if the ADSL line is connected and the Router is properly configured, the ADSL LED will light up after several seconds. If this is your first time installing the device, some settings may need to be changed before the ADSL Router can establish a connection.


Installation

Factory Reset

The Router may be reset to the original factory default settings through the following actions.

1. Press and hold the reset button while the device is powered off using a paper clip or similar object.

2. Turn on the power and the router will restart. Observe the Power LED to verify.

3. Wait for 5~8 seconds and then release the reset button.

4. The device settings will be restored to the factory default IP address 192.168.254.254 and the subnet mask is

255.255.255.0. The default username and password is admin and admin.

Note: A factory reset will erase the current configuration settings and reset them to the default settings.

After restarting your DSL-500B ADSL Router, log in to the router’s web-based interface and use the Setup Wizard to configure the basic settings.


Installation

Network Connections

Connect ADSL Line

Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. Plug one end of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the other end into the

RJ-11 wall socket. If you are using a low pass filter device, follow the instructions included with the device or given to you by your service provider. The ADSL connection represents the WAN interface, the connection to the Internet.

It is the physical link to the service provider’s network backbone and ultimately to the Internet.

Connect Router to Ethernet

The Router may be connected to a single computer or Ethernet device through the 10/100BASE-TX Ethernet port on the rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a speed of 10/100 Mbps only. When connecting the Router to any Ethernet device that is capable of operating at speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port.

Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossover port (MDI-X).

Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the Router directly to a PC or server use a normal straight-through cable. You should use a crossover cable when connecting the Router to a normal (MDI-X) port on a switch or hub. Use a normal straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch. The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable connecting the LAN to the Router does not exceed 100 meters.

Connect Hub or Switch to Router

Connect the Router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable. If you wish to reserve the uplink port on the switch or hub for another device, connect to any of the other MDI-X ports (1x, 2x, etc.) with a crossover cable.

Connect Computer to Router

You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using the

Ethernet cable provided.


Introduction to Web Configuration

The first time you setup the Router. It is recommended that you configure the WAN connection using a single computer, to ensure that both the computer and the Router are not connected to the LAN. Once the WAN connection operates properly, you may continue to make changes to Router configuration, including IP settings and

DHCP setup.

Web-based Configuration Utility

Step 1

Open a web browser such as Internet Explorer on your computer.

Step 2

Type 192.168.254.254 (DSL router default IP address) in the address bar. The login page will appear.

Step 3

Enter a user name and the password. The default username and password of the super user are admin and admin.

If you get a Page Cannot be Displayed error, please refer to the

Troubleshooting section for information.

Note: It is recommended to change these default values after logging in to the DSL router for the first time.

Step 4

Click OK to log in or click Cancel to exit the login page.

After logging in to the DSL router as a super user, you can query, configure, modify all configuration, and diagnose the system.


Web Configuration

Quick Setup

This chapter describes the various menus used to configure and monitor the Router, including how to change IP settings and DHCP server setup.

Note: When subscribing to a broadband service, you should be aware of the method by which you are connected to the Internet. Your physical WAN device can be Ethernet, DSL, or both. For example, your ISP should inform you whether you are connected to the Internet by using a static or dynamic IP address, or the protocols, such as PPPOA or PPPoE, which you use to communicate over the Internet.

Quick Setup enables fast and accurate configuration of your Internet connection and other important parameters.

The following sections describe these various configuration parameters.


Web Configuration

Setting Up VPI/VCI and QoS

After logging in to the DSL router, if no PVC is configured previously and no default settings exist, the Quick Setup webpage will appear This contains some basic configuration that is needed by ATM PVC. The following introduction guides you through the necessary steps to configure your DSL Router.

Based on your ISP's instructions, specify the following parameters:

VP I (Virtual Path Identifier)- Virtual path between two points in an ATM network. The valid value range is from 0 to 255.

VCI (Virtual Channel Identifier)- Virtual channel between two points in an ATM network. The valid value range is from 32 to

65535 (1 to 31 are reserved for known protocols).

Enable Quality of Service - Enabling QoS for a PVC improves performance for selected classes of applications. However, since QoS also consumes system resources, the number of

PVCs are reduced consequently. Go to Advanced Setup >

Quality of Service to assign priorities for the applications.

Check the DSL Auto-connect box and then click Next.

If the ADSL connection is down, uncheck the DSL Auto-connect and then click Next to manually assign the VPI and VCI values.

Web Configuration

NAT

Note: You must enable the NAT service when you configure the WAN connection at first. The NAT item will then appear in the Advanced Setup directory. In the pure bridging mode, there is no NAT service.

Overview - Setting up the NAT Function

The DSL router is equipped with the Network Address Translation (NAT) function. With address mapping, several users in the local network can access the Internet via one or more public IP addresses. All the local IP addresses are assigned to the public IP address of the router by default.

One of the characteristics of NAT is that data from the Internet is not allowed into the local network unless it is explicitly requested by one of the PCs in the network. Most Internet applications can run behind the NAT firewall without any problems. For example, if you request Internet pages or send and receive e-mails, the request for data from the Internet comes from a PC in the local network, and so the router allows the data to pass through. The router opens one specific port for the application. A port in this context is an internal PC address, via which the data is exchanged between the Internet and a client on a PC in the local network. Communicating via a port is subject to the rules of a particular protocol (TCP or UDP).

If an external application tries to send a call to a PC in the local network, the router blocks it. There is no open port via which the data could enter the local network. Some applications, such as games on the Internet, require several links (that is, several ports), so that players can communicate with each other. In addition, these applications must also be permitted to send requests from other users on the Internet to users in the local network. These applications cannot run if NAT is activated.


Web Configuration

Using port forwarding (the forwarding of requests to particular ports), the router is forced to send requests from the Internet for a certain service, for example, a game, to the appropriate port(s) on the PC on which the game is running. Port triggering is a special variant of port forwarding. Unlike port forwarding, the DSL router forwards the data from the port block to the PC which has previously sent data to the Internet via a certain port (trigger port). This means that approval for the data transfer is not tied to one specific PC in the network, but rather to the port numbers of the required Internet service.

Where configuration is concerned, you must define a so-called trigger port for the application and also the protocol

(TCP or UDP) that this port uses. You then assign the public ports that are to be opened for the application to this trigger port. The router checks all outgoing data for the port number and protocol. If it identifies a match of port and protocol for a defined trigger port, then it opens the assigned public ports and notes the IP address of the PC that sent the data. If data comes back from the Internet via one of these public ports, the router allows it to pass through and directs it to the appropriate PC. A trigger event always comes from a PC within the local network. If a trigger port is addressed from outside, the router simply ignores it.

Note:

An application that is configured for port triggering can only be run by one user in the local network at a time.

After public ports are opened, they can be used by unauthorized persons to gain access to a PC in the local network.

When the DSL router is supplied, the NAT function is activated. For example, all IP addresses of PCs in the local network are converted to the public IP address of the router when accessing the Internet. You can use

NAT settings to configure the DSL router to carry out the following tasks.

For functions described as follows, IP addresses of the PCs must remain unchanged. If the IP addresses of the

PCs are assigned via the DHCP server of the DSL router, you must disable DHCP server as the settings in the local network menu entry for the lease time or assign static IP addresses for the PCs.

You can enable or disable the NAT function. By default, the NAT function is enabled.


Web Configuration

NAT - Virtual Server Setup

By default, DSL router blocks all external users from connecting or communicating with your network. Therefore, the system is safe from hackers who may try to intrude into the network and damage it.

However, you may want to expose your network to the Internet in limited and controlled ways in order to enable some applications to work from the LAN (for example, game, voice, and chat applications) and to enable Internet access to servers in the home network. The port forwarding feature supports both functions. This topic is also referred as Local Servers.

The port forwarding page is used to define applications that require special handling by DSL router. All you need to do is to select the application protocol and the local IP address of the computer that is using or providing the service.

If required, you may add new protocols in addition to the most common ones provided by DSL router.

For example, if you wanted to use a file transfer protocol (FTP) application on one of your PCs, you would simply select FTP from the list and enter the local IP address or host name of the designated computer. All FTP-related data arriving at DSL router from the Internet henceforth is forwarded to the specific computer.

Similarly, you can grant Internet users access to servers inside your home network, by identifying each service and the PC that provide it. This is useful, for example, if you want to host a Web server inside your home network.

When an Internet user points his/her browser to DSL router external IP address, the gateway forwards the incoming

HTTP request to your Web server. With one external IP address (DSL router main IP address), different applications can be assigned to your LAN computers, however each type of application is limited to use one computer.

For example, you can define that FTP uses address X to reach computer A and Telnet also uses address X to reach computer A. But attempting to define FTP to use address X to reach both computer A and B fails. DSL router, therefore, provides the ability to add additional public IP addresses to port forwarding rules, which you must obtain from your ISP, and enter into the IP addresses pool. Then, you can define FTP to use address X to reach computer

A and address Y to reach computer B.


Web Configuration

Additionally, port forwarding enables you to redirect traffic to a different port instead of the one to which it was designated. For example, if you have a Web server running on your PC on port 8080 and you want to grant access to this server to any one who accesses DSL router via HTTP.

To accomplish this, do as follows:

Step 1

Define a port forwarding rule for the HTTP service, with the PC IP or host name.

Step 2

Specify 8080 in the Forward to Port field.

All incoming HTTP traffic is forwarded to the PC running the Web server on port 8080. When setting a port forwarding service, ensure that the port is not used by another application, which may stop functioning. A common example is when using SIP signaling in Voice over IP, the port used by the gateway VoIP application (5060) is the same port, on which port forwarding is set for LAN SIP agents.

Note: Some applications, such as FTP, TFTP, PPTP and H323, require the support of special specific application level gateway (ALG) modules in order to work inside the home network. Data packets associated with these applications contain information that allows them to be routed correctly. An ALG is needed to handle these packets and ensure that they reach their intended destinations. DSL router is equipped with a robust list of ALG modules in order to enable maximum functionality in the home network. The ALG is automatically assigned based on the destination port.

Virtual servers are configured for this purpose.


Web Configuration

Adding Port Forwarding

Step 1

To set up virtual servers for a service, go to Advanced Setup >

NAT > Virtual Servers, and then click Add.

Step 2

Select a service or enter a custom server.

Step 3

Set the Server IP Address.

Step 4

Enter the server IP address of the computer that provides the service (the server in the local host field). Note that unless an additional external IP address is added, only one LAN computer can be assigned to provide a specific service or application.

Step 5

Set External Port Start and External Port End.

Step 6

Select a Protocol from the drop-down box.

Step 7

Set Internal Port Start and Internal Port End.

Step 8

Enter Remote IP.


Web Configuration

Step 9

Click Save/Apply to apply the settings.

If the application you require is not in the list, manually enter the information.

Select the protocol for the service you are providing from the Protocol drop-down list. Under External Port, enter the port number of the service you are providing. In the Internal Port field, enter the internal port number, to which service requests are to be forwarded. In the Local IP Address field, enter the IP address of the PC that provides the service.

Example

The Web server is configured to react to requests on port 8080. However, the requests from websites enter the Web server via port 80 (standard value). If you add the PC to the forwarding table and define port 80 as the public port and port 8080 as an internal port, all requests from the Internet are diverted to the service with port 80 on the Web server of the PC you have defined with port 8080.

Deleting Port Forwarding

Step 1

Select the Remove check box.

Step 2


Port Triggering

If you configure port triggering for a certain application, you must determine a so-called trigger port and the protocol

(TCP or UDP) that this port uses. You then assign the public ports that are to be opened for the application to this trigger port. You can select known Internet services or manually assign ports or port blocks.


Web Configuration

Adding Port Triggering

Step 1

To set up port triggering for a service, select Advanced Settings >

NAT > Port Triggering, and click Add.

Step 2

Select the required application from the Select an application drop-down list, or manually enter the information in the Custom

application field.

Step 3

Trigger Port Start and Trigger Port End: Enter the port that is to be monitored for outgoing data traffic.

Trigger Protocol: Select the protocol that is to be monitored for outgoing data traffic.

Open Protocol: Select the protocol that is to be allowed for incoming data traffic.

Open Port Start and Open Port End: Enter the port that is to be opened for incoming traffic.

Step 4


Removing Port Triggering

Step 1

Select the Remove check box.

Step 2



Web Configuration

DMZ Host

The demilitarized military zone (DMZ) host feature allows one local computer to be exposed to the Internet. This function is applicable for:

Users who want to use a special-purpose Internet service, such as an on-line game or video conferencing program, that is not in the port forwarding list and for which no port range information is available.

Users who are not concerned with security and wish to expose one computer to all services without restriction.

Note: A DMZ host is not protected by the firewall and may be vulnerable to attack. This may also put other computers in the home network at risk. Hence, when designating a DMZ host, you must consider the security implications and take the appropriate precautions.

You can set up a client in your local network as a DMZ host. Your device then forwards all incoming data traffic from the Internet to this client. You can, for example, operate your own Web server on one of the clients in your local network and make it accessible to Internet users. As the exposed host, the local client is directly visible to the Internet and therefore particularly vulnerable to attacks (for example, hacker attacks). Enable this function only when necessary (for example, to operate a Web server) and when other functions (for example, port forwarding) are inadequate. In this case, you should take appropriate measures for the clients concerned.

Note: Only one PC per public IP address can be set up as an exposed host.


Web Configuration

Adding a DMZ Host

Step 1

To set up a PC as a DMZ host, select Advanced Setup > NAT >

DMZ Host.

Step 2

Enter the local IP address of the PC that is to be enabled as an exposed host.

Step 3


Remove DMZ host

Click Save/Apply to add the URL filter.


Web Configuration

Quality of Service

Many communication and multimedia applications require large, high-speed bandwidths to transfer data between the local network and the internet. However, for many applications there is often only one internet connection available with limited capacity. QoS divides this capacity between the different applications and provides undelayed, continuous data transfer in situation where data packets with higher priority are given preference.

Network QoS is an industry-wide set of standards and mechanisms for ensuring high-quality performance for critical applications. By using QoS mechanisms, network administrators can use existing resources efficiently and ensure the required level of service without reactively expanding or over-provisioning their networks.

Enabling QoS

Select Advanced Setup > Quality of Service. In this page, you can perform QoS queue management configuration. By default, the system enables QoS and sets a default DSCP mark to automatically mark incoming traffic without reference to particular classifier.

Select Enable QoS to enable QoS and set the default DSCP mark.

Click Save/Apply to activate QoS.


Web Configuration

QoS Queue Configuration

The queuing in packet QoS becomes effective only when packet is forwarded to QoS-enabled PVC. Packet forwarding is determined by IP routing or bridging, not under control of the packet QoS.

Select Advanced Setup > Queue Config. In this page, you can configure QoS queue. A maximum of 24 entries can be configured.

QoS Queue Configuration can allocate four queues. Each of the queues can be configured for a precedence value (Lower integer values for precedence imply higher priority for this queue relative to others). The queue entry configured is used by the classifier to place ingress packets appropriately.

Note: Lower integer values for precedence imply higher priority for this queue relative to others. For example, add a QoS queue entry and allocate it to a specific network interface (PVC 0/0/35). Set integer values for queue precedence to 1.

Click Add to configure a QoS Queue configuration entry.


Web Configuration

Step 1

This page allows you to configure a QoS queue entry and then assign it a specific network interface.

Queue Configuration Status: Set to enable or disable a QoS queue.

Queue: Select a specific network interface. When you have already selected a network interface, the specific network interface selected automatically allocates to the queue.

Queue Precedence: Select an integer value for queue precedence.

After you select an integer value, the queue entry appropriately places to ingress packets. Lower integer values for precedence imply higher priority for this queue relative to others.


After the queue is configured, you can create several traffic class rules to classify the upstream traffic.


Web Configuration

QoS Classification

Some applications require specific bandwidth to ensure its data be forwarded in time. QoS classification can creates traffic class rule to classify the upstream traffic. Assign queue which defines the precedence and the interface and optionally overwrite the IP header DSCP byte. After QoS classification, QoS divides capacity between different applications and provides undelayed, continuous data transfer where data packet with higher priority is given preference. The follow figure shows QoS classification.


Web Configuration

Select Advanced Setup > QoS Classification. In this page, you can configure network traffic classes.

Click Add to create a traffic class rule to classify the upstream traffic.

Traffic Class Name: Enter a name of the class.

Rule Order: Select order for queue.

Rule Status: Enable or disable this traffic class rule.

Assign Classification Queue: Select a classification queue.

Assign Differentiated Service Code Point (DSCP) Mark:

Select a mark service that modifies the original packet IP header if all rules defined within the classification class are matched.

(CS-Mark IP Precedence, AF-Assured Forwarding, EF-Expedited

Forwarding)

Mark 802.1p if 802.1q is Enabled: Select an 802.1p priority number that serves as the 802.1p value.

There are two sets of classification rules. Set-1 is based on different fields within TCP/UDP/IP layer plus physical LAN port;

Set-2 is based on IEEE 802.1p priority field.


Web Configuration

Set-1 rules contain the following:

Physical LAN Port: Select one among USB port, Ethernet ports and wireless port.

Protocol: Select one among TCP/UDP TCP UDP or ICMP protocols.

Source IP Address

Source subnet mask

UPD/TCP Source Port

Destination IP Address

Destination Subnet Mask

UPD/TCP destination port or a range of ports

Source Mac Address

Source Mac Mask

Destination Mac Address

Destination Mac Mask

Set-2 rules contain the following:

802.1p Priority: the 802.1p header includes a 3-bit prioritization field, which allows packets to be grouped into eight levels of priority

(0-7), where level 7 is the highest one.

Click Save/Apply to save and activate this rule.


Web Configuration

QoS-DSCP Setting

In order to understand what is differentiated services code point (DSCP), you should be familiar with the differentiated services model (Diffserv).

Diffserv is a class of service (CoS) model that enhances best-effort Internet services via differentiating traffic by users, service requirements and other criteria. Packets are specifically marked, allowing network nodes to provide different levels of service via priority queuing or bandwidth allocation, or by choosing dedicated routes for specific traffic flows.

As displayed in following diagram, the IPV4 packet has a TOS filed. Diffserv defines TOS field in IP packet headers referred to as DSCP. Hosts or routes that pass traffic to a Diffserv-enabled network typically mark each transmitted packet with an appropriate DSCP. The DSCP markings are used by Diffserv network routers to appropriately classify packets and to apply particular queue handing or scheduling behavior.

The IEEE 802.1p priority marking method is a standard for prioritizing network traffic at the data link/Mac sub-layer

802.1p traffic is simply classified and sent to the destination, with no bandwidth reservations established.

The follow diagram shows the structure of 802.1Q Frame. The 802.1Q header includes a 3-bit prioritization field, which allows packets to be grouped to be grouped into eight levels of priority (0-7), where level 7 is the highest one.

In addition, DSL maps these eight levels to priority queues, where queue 1 has the highest priority.

Troubleshooting

This chapter provides solutions to problems that might occur during the installation and operation of the DSL-500B.

(The examples below are illustrated in Windows ® XP. If you have a different operating system, the screenshots on your computer will look similar to the following examples.)

1. How do I configure my DSL-500B Router without the CD-ROM?

Connect your PC to the Router using an Ethernet cable.

Open a web browser and type http://192.168.254.254.

The default username is admin and the default password is admin.

If you have changed the password and cannot remember it, you will need to reset the Router to the factory default setting (see question 2). This default password is admin.

Note: If you cannot see the login window, please refer to the next section - Network Basics to check your PC’s IP configuration.

2. How do I reset my Router to the factory default settings?

Ensure that the Router is powered on.

Press and hold the reset button on the back of the device for few seconds.

This process would take about 1~2 minutes to complete.

Note: Resetting the Router to the factory default settings will erase the current configuration settings. To reconfigure your settings, log in to the Router as outlined in question 1.


Appendix A - Troubleshooting

3. What can I do if my Router is not working correctly?

Here are a few steps that you can follow to resolve the issue:

Follow the directions highlighted in question 2 to reset the Router.

Check if all the cables are firmly connected at both ends.

Check the LEDs on the front of the Router. The Power indicator, DSL and LAN indicators should be illuminated.

Please ensure that the settings in the Web-based configuration manager, e.g. ISP username and password, are the same as the settings provided by your ISP.

4. Why can’t I connect to the Internet?

For ADSL subscribers, please contact your ISP to make sure the ADSL service has been enabled, and your ISP username and password are correct.


Appendix A - Troubleshooting

4. What can I do if my router can’t be detected by the installation CD?

Ensure the Router is powered on.

Check if all the cables are firmly connected at both ends and all the LEDs are working correctly.

Ensure that only one network interface card on your PC is activated.

Disable Windows Firewall.

In Windows XP, go to Start > Control Panel and then double-click Security Center.

Disable the Windows Firewall setting and click OK.

Note: There might be a potential security issue if you disable the Firewall setting on your PC. Please remember to turn it back on once you have finished the installation procedure and successfully installed your router.


Networking Basics

Check Your IP Address

After you install your new D-Link adapter, the TCP/IP settings, by default should be set to Obtain an IP address from a DHCP

server automatically. To verify your IP address, please follow the steps below.

Click Start > Run. In the run box type cmd and click OK. At the prompt, type ipconfig and press Enter.

This will display the IP address, subnet mask, and the default gateway of your adapter.

If the address is 0.0.0.0, check your adapter installation, security settings, and the settings on your router. Some firewall software programs may block a DHCP request on newly installed adapters.


Appendix B - Networking Basics

Statically Assign An IP Address

If you are not using a DHCP capable gateway/router, or if you need to assign a static IP address, please follow the steps below:

Step 1

Windows ® XP: Click Start > Control Panel > Network Connections.

Windows ® 2000: From the desktop, right-click My Network Places >

Properties.

Step 2

Right-click on Local Area Connection that represents your D-Link network adapter and select Properties.

Step 3

Highlight Internet Protocol (TCP/IP) and click Properties.

Step 4

Click on Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN IP address on your router.

Example: If the router’s LAN IP address is 192.168.254.254, make your IP address 192.168.254.X where X is a number between 2 and 254. Make sure that the number you choose is not in use on the network. Set Default

Gateway the same as the LAN IP address of your router (192.168.254.254).

Set Primary DNS address the same as the LAN IP address of your router (192.168.254.254). The Secondary DNS is not needed or you may enter a DNS server from your ISP.

Step 5

Click OK twice to save your settings.
