200 MHz Processor 64MB Memory CD-ROM Drive Ethernet Adapter with TCP/IP Protocol Installed Computer with Windows 2000, Windows XP, or Windows Vista Internet Explorer v6 or later, FireFox v1.5 D-Link DSL-2600U User Manual 1 Product Overview 1 Features PPP (Point-to-Point Protocol) Security The DSL-2600U ADSL Router supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections. The Router also supports MSCHAP. 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-2600U allows multiple users on the 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-2600U supports TCP/IP protocol, the language used for the Internet. It is compatible with access servers manufactured by major vendors. enabled devices. RIP-1/RIP-2 The DSL-2600U supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions lets the Router to communicate with all RIP 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). 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. 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. network management. Full Network Management The DSL-2600U incorporates SNMP (Simple Network Management Protocol) support for web-based management and text-based Easy Installation The DSL-2600U 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.

D-Link DSL-2600U User Manual 4 Installation Installation This section will walk you through the installation process. Placement of the Wireless 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 Wireless 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 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-2600U 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. 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 D-Link DSL-2640B User Manual 5 Installation 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 NIC configuration that may be required. Wireless LAN Computers using the Wireless network can access the Internet or use the embedded 802.1g wireless access point. Wireless workstations must have an 802.1g or 802.1b wireless network card installed to use the Wireless ADSL Router. In addition the workstations must be configured to operate on the same channel and SSID as the Wireless ADSL Router. If wireless security is used, the wireless workstations must be properly configured for the security settings used. D-Link DSL-2640B User Manual 6 Installation Information you will need from your ADSL service provider Username This is the Username used to log on to your ADSL service providers 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 providers 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 configurations (Connection Type settings listed in parenthesis):
PPPoE/PPPoA (PPPoE LLC, PPPoE VC-Mux, 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. 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 providers 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. D-Link DSL-2640B User Manual 7 Installation Information you will need about DSL-2600U Username This is the Username needed to access the Routers 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. The user cannot change this. Password This is the Password you will be prompted to enter when you access the Routers management interface. The default Password is admin. The user may change this. LAN IP addresses for the DSL-2600U This is the IP address you will enter into the Address field of your web browser to access the Routers configuration graphical user interface (GUI) using a web browser. The default IP address is 10.1.1.1. 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-2600U This is the subnet mask used by the DSL-2600U, and will be used throughout your LAN. The default subnet mask is 255.0.0.0. This can be changed later. Information you will need about your LAN or computer:
Ethernet NIC If your computer has an Ethernet NIC, you can connect the DSL-2600U to this Ethernet port using an Ethernet cable. You can also use the Ethernet ports on the DSL-2600U to connect to other computer or Ethernet devices. DHCP Client status Your DSL-2600U ADSL Router is configured, by default, to be a DHCP server. 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-2600U will assign are from 10.1.1.5 to 10.1.1.254. Your computer (or computers) needs to be configured to obtain an IP address automatically (that is, they need to 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-2600U ADSL Router. D-Link DSL-2640B User Manual 8 Installation Device Installation The Wireless ADSL Router maintains three separate interfaces, an ADSL, an Ethernet, and a Wireless LAN interface. Place the Wireless ADSL Router in a location where it can be easily connected to Ethernet devices, the telephone line as well as to 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 if you need to view them for troubleshooting. Power on Router The Router must be used with the power adapter included with the device. 1. Connect the power adapter to the Power Input (12V DC, 1A) on the back panel of the Wireless ADSL Router and plug the other end of the power adapter to a wall outlet or power strip. 2. Push the Power Button to turn the power on. 3. The Power LED on the front panel will shine 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 Wireless ADSL Router will attempt to establish the ADSL connection, if the ADSL line is connected and the Wireless ADSL Router is properly configured the ADSL LED will light up after several seconds. If this is the first time installing the device, some settings may need to be changed before the Wireless ADSL Router can establish a connection. Factory Reset Button The Router may be reset to the original factory default settings by using a ballpoint or paperclip to gently push down the reset button in the following sequence:
1. With the router powered on (check the Power LED to make sure it lights steady green), press and hold down the reset button using a paper clip or similar object for about 6 to 8 seconds. 2. The router will restart. Watch the Power LED to verify that it is restarting. 3. When it is powered on again it is ready to be configured. The whole process takes about 30 seconds. 4. The device settings will be restored to the factory default IP address 10.1.1.1 and the subnet mask is 255.0.0.0, the default management Username is admin and the default Password is admin. Note: A factory reset will erase the current configuration settings and reset them to the default settings. After it has restarted, log in to the router management interface and use the Setup Wizard to configure the basic settings. s web-based D-Link DSL-2640B User Manual 9 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 providers 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 crossed 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 crossed 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. Hub or Switch to Router Connection 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 on the other MDI-X ports (1x, 2x, etc.) with a crossed cable. Computer to Router Connection You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided. Wireless Connection to Router The Routers embedded 802.11g wireless access point should be configured to suit the local wireless network. All 802.11g or 802.11b devices that associate with the Routers wireless access point must have the same SSID and channel. If wireless security is used, the wireless clients must be configured with the correct security information to use the Router. More information on configuring the wireless settings is found later in this manual. D-Link DSL-2640B User Manual 10 Web Configuration 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. This chapter is concerned with using your computer to configure the WAN connection. The following chapter describes the various menus used to configure and monitor the Router, including how to change IP settings and DHCP server setup. Preparation Before Login Before accessing the Modem, ensure the communication between PC and Modem is normal. Check the communication as follows.
= Configure the IP address of the PC as 10.1.1.X (2~254), net mask as 255.0.0.0, gateway address as 10.1.1.1 (for customized version, configure them according to the actual version).
= Enter arp -a in the DOS window to check whether the PC can read the MAC address of the Modem.
= Ping the management IP address (10.1.1.1 by default) of the Modem. If the PC can read the MAC address of the Modem and can ping through the management IP address of the Modem, that means the communication of the PC and the Modem is normal. D-Link DSL-2600U User Manual 11 Web Configuration Note: When you manage the Modem through Web, you must keep the Modem power on. Otherwise, the Modem may be damaged. D-Link DSL-2600U User Manual 12 Web Configuration Logging In to the Modem The following description is a detail How-To user guide and is prepared for first time users. First-Time Login When you log in to the DSL Router for the first time, the login wizard appears. Step 1 Open a Web browser on your computer. Step 2 Enter http://10.1.1.1 (DSL router default IP address) in the address bar. The login page appears. Step 3 Enter a user name and the password. The default username and password of the super user are admin and admin. The username and password of the common user are user and user. You need not enter the username and password again if you select the option Remember my password. 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, and modify all configurations, and diagnose the system. You need to reboot the DSL router to enable your modification or configuration effective in some cases, for example, after you modify the PVC configuration. Some modification, such as adding a static route, takes effect at once, and does not require modem reboot. D-Link DSL-2600U User Manual 13 Web Configuration Quick Setup The Quick Setup page mainly includes the following three functions:
= WAN interface setup
= LAN interface setup
= Wireless interface setup Quick setup enables fast and accurate configuration of your Internet connection and other important parameters. The following sections describe these various configuration parameters. Whether you configure these parameters or use the default ones, click Next to enable your Internet connection. 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. Technical information regarding the properties of your Internet connection should be provided by your Internet service provider (ISP). 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. WAN Interface Setup During WAN interface setup, you can set up a PVC and its properties:
= VPI
= VCI
= QoS
= Internet connection type
= Encapsulation type
= IGMP service
= NAT 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 appears, which contains some basic configuration that is needed by ATM PVC. The following introduction guides you through the necessary steps to configure your DSL Router. D-Link DSL-2600U User Manual 14 Web Configuration According to your ISP instructions, specify the following parameters:
= VPI (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 is reduced consequently. Use Advanced Setup/Quality of Service to assign priorities for the applications. For example, PVC 0/35 is to be modified and the default values of QoS remain. In actual applications, you can modify them depending on your ISP instructions. Selecting Internet Connection Type and Encapsulation Type You can select your connection type from the following list. Each connect type corresponds to several encapsulation types:
= PPP over ATM (PPPoA) PPPoA Encapsulation Mode: VC/MUX, LLC/ENCAPSULATION

In the Bridging mode, the interface shows different. NAT Note: You need to enable the NAT service when you configure the WAN connection at first, the NAT item appears in the Advanced Setup directory. In the pure bridging mode, there is not the 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 D-Link DSL-2600U User Manual 32 Web Configuration 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.
= 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 disenable the NAT function. By default, the NAT function is enabled. NAT-Virtual Server Setup By default, DSL router blocks all external users from connecting to 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 functionalities. 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. D-Link DSL-2600U User Manual 33 Web Configuration 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. 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. Adding Port Forwarding Step 1 To set up virtual servers for a service, select Advanced Setup > NAT > Virtual Servers, and click Add. D-Link DSL-2600U User Manual 34 Web Configuration Step 2 Select a service or enter a custom server. Step 3 Set 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 Protocol. Step 7 Set Internal Port Start and Internal Port End. Step 8 Enter Remote IP. 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 Click Remove to apply the settings. Port Triggering If you configure port triggering for a certain application, you need to 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. Adding Port Triggering D-Link DSL-2600U User Manual 35 Step 1 To set up port triggering for a service, select Advanced Settings > NAT > Port Web Configuration 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.

Removing Port Triggering Step 1 Select the Remove check box. Step 2 Click Save/Apply to apply the settings. 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 presented 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 protect it if necessary. D-Link DSL-2600U User Manual 36 Web Configuration You can set up a client in your local network as a so-called 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. 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 Click Save/Apply to apply the settings. Remove DMZ host Step 1 Clear the DMZ Host Address. Step 2 Click Save/Apply to apply the settings. Security Click Security > IP Filtering and the following interface appears. By default, the firewall is enabled. The firewall is used to block document transmissions between the Internet and your PC. It serves as a safety guard and permits only authorized documents to be sent to the LAN.

If dont enter port number, default 80 will be appled. 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. Click Quality of Service and the following page appears. Under Quality of Service, there are two network share modes: Queue Config and QoS Classification. 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. Traditionally, the concept of quality in networks meant that all network traffic was treated equally. The result was that all network traffic received the networks best effort, with no guarantees for reliability, delay, variation in delay, or other performance characteristics. With best-effort delivery service, however, a single bandwidth-intensive application can result in poor or unacceptable performance for all applications. The QoS concept of quality is one in which the requirements of some applications and users are more critical than others, which means that some traffic needs preferential treatment. The order of source packet 1. classify 2. CAR/GTS 3. queuing QOS diapose The order of outgoing packet Internet CPE 42 D-Link DSL-2600U User Manual Web Configuration Enabling QoS 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 Advanced Setup > Quality of Service and the following page appears. Select Enable QoS to enable QoS and set the default DSCP mark. Click Save/Apply to activate QoS. 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. Click Queue Config, and the following page appears. 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. D-Link DSL-2600U User Manual 43 Web Configuration Step 1 Click Add, and the following page appears.
= Policy Select: you can select Strict Priority Policy or WRR Policy.
= 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. Step 2 Add a QoS queue entry and assign it to a specific network interface (PVC 0/0/35), and set integer values for queue precedence to 1. See the following figure:
D-Link DSL-2600U User Manual 44 Web Configuration Step 3 After proper modifications, click Save/Apply and the following page appears. This configuration takes effective at once. To delete a certain queue, disable it, select it, and then click Remove. After the queue is configured, you can create several traffic class rules to classify the upstream traffic. WRR (Weighted Round Robin): this is another QoS method. If you want to set WRR, you must disable the Strict-Priority Queue (PQ). The WRR is mutex to PQ. Only one QoS method can exist at the same time. Select WRR in QoS Queue Configuration page. The following interface appears. For example, add a QoS queue entry and allocate it to a specific network interface (PVC 0/2/35). Set queue precedence to 2 and weight value to 30%. D-Link DSL-2600U User Manual 45 Web Configuration After proper modifications, click Save/Apply and the following page appears. The weighted round robin (WRR) queue schedule divides each port into several output queues. Queues are scheduled in turn to ensure that each queue obtains a certain service time. WRR configures a weighted value (w3, w2, w1 and w0) for each queue. The weighted value represents the proportion of the obtained resources. For example, the weighted value of WRR queue schedule algorithm of a 100M port is configured as 50, 30, 10 and 10 (corresponding to w3, w2, w1 and w0), so that the queue with minimum priority obtains a bandwidth of at least 10Mbps, which avoids the disadvantage that a message in queue with low priority during PQ schedule may not obtain service for a long time. WRR queue still has another advantage. Although the schedule of these queues are conducted in turn, each queue is not assigned with a fixed service time slice-if a certain queue is null, it is immediately changed to the next queue. In this way, the bandwidth resources can be fully utilized. QoS-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. D-Link DSL-2600U User Manual 46 Web Configuration Click QoS Classification and the following page appears. In this page, you can configure network traffic classes. Click Add and the following page appears.

= 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 MAC layer IEEE 802.1p priority field. Set-1 Rules contain the following:
= Physical LAN Port: Select one among USB port, Ethernet ports and wireless port.

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. D-Link DSL-2600U User Manual 47 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.

Wireless This section introduces the wireless LAN and some basic configurations. Wireless LAN can be as simple as two computers with wireless LAN cards communicating in a peer-to-peer network or as complex as a number of computers with wireless LAN cards communicating through access points (AP) that bridge network traffic to the wired LAN. The Modem Wi-Fi certified IEEE 802.11g compliant wireless access point allows multiple computers to connect wirelessly to your local network over the Modem Wireless LAN environment. The Modem is backward compatible with IEEE 802.11b, which means 802.11b and 802.11g devices can coexist in the same wireless network. The Wireless Distribution System (WDS) on your Modem allows you to extend the range of your wireless network. To be able to use WDS, you will need to introduce an additional WDS-enabled access point into your wireless network. To be able to connect the computers, make sure that a wireless client adapter (WLAN client) is installed on each computer you want to connect via the WLAN. Wireless LAN Basics Some basic understanding of 802.11b/g wireless technology and terminology is useful when you are setting up the Router or any wireless access point. If you are not familiar with wireless networks please take a few minutes to learn the basics. Wireless client requirements All wireless client adapters compliant to 802.11g and/or 802.11b can communicate with the Modem (W) LAN environment. However, be aware that only 802.11g compliant wireless clients are able to gain full profit of the 54 Mb/s (Max) bandwidth delivered by the Modem. It is highly recommended to use only wireless client adapters that are Wi-Fi certified to ensure smooth interoperability with the Modems WLAN. Radio Transmission Wireless LAN or WLAN devices use electromagnetic waves within a broad, unlicensed range of the radio spectrum to transmit and receive radio signals. When a wireless access point is present, it becomes a base station for the WLAN nodes in its broadcast range. WLAN nodes transmit digital data using FM (frequency modulation) radio D-Link DSL-2600U User Manual 60 Web Configuration signals. WLAN devices generate a carrier wave and modulate this signal using various techniques. Digital data is superimposed onto the carrier signal. This radio signal carries data to WLAN devices within range of the transmitting device. The antennae of WLAN devices listen for and receive the signal. The signal is demodulated and the transmitted data extracted. The transmission method used by the access point is called Direct Sequence Spread Spectrum (DSSS) and operates in a range of the radio spectrum between 2.4GHz and 2.5GHz for transmission. See the expert technical specifications for more details on wireless operation. Antennas Direct the external antenna to allow optimization of the wireless link. If for example the antenna is erect, wireless links in the horizontal plane are favored. Please note that the antenna characteristics are influenced by the environment, that is, by reflections of the radio signal against walls or ceilings. It is advisable to use the received signal strength as indicated by the wireless client manager to optimize the antenna position for the link to a given client. Concrete walls weaken the radio signal and thus affect the connection. Range Range should not be a problem in most homes or small offices. If you experience low or no signal strength in some areas, consider positioning the Router in a location between the WLAN devices that maintains a roughly equal straight-line distance to all devices that need to access the Router through the wireless interface. Adding more 802.11g access points to rooms where the signal is weak can improve signal strength. Read the section about placement of the Router titled Location in the next chapter, Hardware Installation, for more information. SSID Wireless networks use an SSID (Service Set Identifier) to allow wireless devices to roam within the range of the network. Wireless devices that wish to communicate with each other must use the same SSID. Several access points can be set up using the same SSID so that wireless stations can move from one location to another without losing connection to the wireless network. The Modem operates in Infrastructure mode. It controls network access on the wireless interface in its broadcast area. It will allow access to the wireless network to devices using the correct SSID after a negotiation process takes place. By default the Modem broadcasts its SSID so that any wireless station in range can learn the SSID and ask permission to associate with it. Many wireless adapters are able to survey or scan the wireless environment for access points. An access point in Infrastructure mode allows wireless devices to survey that network and select an access point with which to associate. You may disable SSID broadcasting the wireless menu of web management. Radio channels The 802.11g standard allows several WLAN networks using different radio channels to be co-located. The Modem supports multiple radio channels and is able to select the best radio channel at each startup. You can choose to set the channels automatically or manually. The different channels overlap. To avoid interference with another access point, make sure that the separation (in terms of frequency) is as high as possible. It is recommended to keep at least 3 channels between 2 different access points. The Modem supports all channels allowed for wireless networking. However, depending on local regulations, the number of channels actually allowed to be used may be additionally restricted, as shown in the table below. Regulatory Domain China Europe Israel Japan Jordan Thailand USA / Canada Allowed Radio Channels 1 to 13 1 to 13 5 to 8 1 to 14 10 to 13 1 to 14 1 to 11 61 D-Link DSL-2600U User Manual Web Configuration Wireless Security Various security options are available on the Modem including open or WEP, 802.1x, WPA, WPA-PSK, WPA2 and WPA2-PSK. Authentication may use an open system or a shared key. For details on these methods and how to use them, please read the wireless LAN configuration information in Section 3.5.3 (Wireless Security Configuration). About 802.11g Wireless 802.11b is an IEEE standard, operating at 2,4 GHz at a speed of up to 11 Mb/s. 802.11g, a newer IEEE standard also operating at 2,4 GHz, gives you up to 54 Mb/s speed, more security and better performance. Today's 11-megabits-per-second 802.11b wireless networks are fine for broadband Internet access (which typically tops out at about 1 mbps) but rather slow for large internal file transfers or streaming video. However, 54-mbps, corporate-oriented 802.11a is expensive and because its radio uses the 5-GHz band and 802.11b uses the 2.4 GHz band, upgrading to an 802.11a network means either scrapping 802.11b gear or buying even-pricier hardware that can support both standards. But 802.11g promises the same speed as 802.11a and the ability to coexist with 802.11b equipment on one network, since it too uses the 2.4-GHz band. 802.11g is an extension to 802.11b, the basis of many wireless LANs in existence today. 802.11g will broaden 802.11b's data rates to 54 Mbps within the 2.4 GHz band using OFDM
(orthogonal frequency division multiplexing) technology. Because of backward compatibility, an 802.11b radio card will interface directly with an 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. You should be able to upgrade the newer 802.11b access points to be 802.11g compliant via relatively easy firmware upgrades. Similar to 802.11b, 802.11g operates in the 2.4GHz band, and the transmitted signal uses approximately 30MHz, which is one third of the band. This limits the number of non-overlapping 802.11g access points to three, which is the same as 802.11b. Note: Maximum wireless signal rate based on IEEE Standard 802.11g specifications is 54 Mbps. But actual data throughput varies depending on network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead will cause lower actual data throughput rate. Access Point and Wireless Fidel The Wi-Fi certification ensures that your Modem will interoperate with any Wi-Fi certified 802.11g and 802.11b compliant wireless device. The Modem Wireless LAN Access Point (AP) behaves as a networking hub allowing to wirelessly interconnect several devices to the local (W) LAN and to provide access to the Internet.

D-Link DSL-2600U User Manual 81 Troubleshooting Troubleshooting This chapter provides solutions to problems that might occur during the installation and operation of the DSL-2600U. Read the following descriptions if you are having problems. (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-2600U Router without the CD-ROM?
= Connect your PC to the Router using an Ethernet cable.
= Open a web browser and enter the address http://10.1.1.1 .
= 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), Note:
which will set the password back to admin. Please refer to next section Network Basics to check your PCs IP configuration if you cant see the login window. 2. How do I reset my Router to the factory default settings?
= Ensure the Router is powered on.
= Press and hold the reset button on the back of the device for about one second.
= 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. 3. What can I do if my Router is not working correctly?
There are a few quick steps you can take to try and resolve any issues:
= Follow the directions in question 2 to reset the Router.
= Check that all the cables are firmly connected at both ends.
= Check the LEDs on the front of the Router. The Power indicator should be on, and the DSL and LAN indicators should be on as well.
= Please ensure that the settings in the Web-based configuration manager, e.g. ISP username and password etc., are the same as the settings provided by your ISP. 4. Why can t I get an Internet connection?
For ADSL subscribers, please contact your ISP to make sure the ADSL service has been enabled, and your ISP username and password are correct. D-Link DSL-2600U User Manual 82 Networking Basics Check Your IP Address Networking Basics After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless router) 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. If you are connecting to a wireless network at a hotspot (e.g. hotel, coffee shop, airport), please contact an employee or administrator to verify their wireless network settings. D-Link DSL-2600U User Manual 83 Statically Assign An IP Address Statically Assign An IP Address If you are not using a DHCP capable gateway/router, or 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 the 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 the 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 routers LAN IP address is 10.1.1.1, make your IP address 10.1.1.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 (10.1.1.1). Set Primary DNS the same as the LAN IP address of your router (10.1.1.1). The Secondary DNS is not needed or you may enter a DNS server from your ISP. Step 5 Click on the OK twice to save your settings.
