FCC ID: KA2SL2640RD Wireless ADSL2+ Router

Basic Wireless Section 3 Configuration To disable the wireless interface: click in the Deactivated option next to Access Point: and click the SAVE button. This will immediately disable the wireless access point; it is not necessary to restart the access point to make this change. If the wireless interface has been disabled: click in the Activated option next to Access Point: and click the SAVE button. This will immediately disable the wireless access point; it is not necessary to restart the access point to make this change. The SSID can be changed to suit your wireless network. Remember that any wireless device using the access point must have the same SSID and use the same channel. The SSID can be a continuous character string

(i.e. no spaces) of up to 16 characters in length. The Channel ID: may be changed to channels that are available in your region. Channels available for wireless LAN communication are subject to regional and national regulation. Click the SAVE button to save any change to the Channel. Wireless Security The wireless security features are used to limit access to the device or to encrypt data and shared information. The available standardized security for wireless LAN includes WEP and WPA Wireless security is configured with the Wireless Settings menu located in the Home directory. In the Wireless Settings menu, select the type of security you want to configure. The menu will change to present the settings specific to the method being configured. The Routers wireless security options include three levels of WEP encryption and WPA with a user configured Pre Shared Key (PSK). Configure the wireless security arrangement to suit your 802.11g environment and click the SAVE button. The settings will go into effect immediately. There is no need to restart the access point. The table below provides a summary of the settings in the Wireless Settings menu. Note: Before enabling any security function for wireless operation, you may want to test the Routers access point first to verify that wireless workstations can associate with it and use it for Internet access. D-Link DSL-2640R User Manual 28 WEP Encryption Section 3 Configuration WEP (Wireless Encryption Protocol or Wired Equivalent Privacy) encryption can be enabled for security and privacy. WEP encrypts the data portion of each frame transmitted from the wireless adapter using one of the predefined keys. Decryption of the data contained in each packet can only be done if the both the receiver and transmitter have the correct key. By default authentication is disabled on the access point. To enable WEP, select the WEP-64Bits or WEP-128Bits option, configure the WEP Encryption Keys as desired and click the SAVE button. The encryption key setup is described below. Encryption Keys WEP Keys may be configured using Hex or ASCII characters. There are two levels of encryption available, each level requires a different number of characters. Select Hex or ASCII from the Key Type drop-down menu. Hex or Hexadecimal digits are defined as the numerical digits 0 9 and the letters A F (upper and lower case are recognized as the same digit). ASCII characters include numbers and letters but no spaces. An upper case ASCII character is NOT recognized as the same lower case character, and therefore must be configured exactly as typed for all wireless nodes using the access point. The length of the key depends on the level of encryption used. Select the Key Length from the drop-down menu. The available key lengths are 64 or 128-bit encryption. In the spaces provided, type in Key 1, Key 2, Key 3 and Key 4. The length of the character string used of the keys depends on the level (Key Length) of encryption selected. Only one key can be active. The active key is selected by clicking the radio button for the key you want to use. Click the SAVE button when you have configured WEP as desired to put the changes into effect. D-Link DSL-2640R User Manual 29 WPA Settings Section 3 Configuration WPA uses an encryption method combined with an authentication procedure that requires an acceptance of a pre-configured password. WPA or Wireless Protection Access is an improved standard of wireless security. The ROUTER also supports two common encryption types TKIP and AES. To configure WPA settings, select the Authentication Type option WPA-PSK to use TKIP encryption or select WPA2-PSK to use AES encryption. The encryption algorithm TKIP (Temporal Key Integrity Protocol) uses per packet key generation (based on WEP), while AES (Advanced Encryption Standard) is a block-

based encryption method. Both methods require entry of a pre-shared key to allow association. Type a password from 8 to 64 characters long in the Pre-Shared Key field. Wireless MAC Address Filter MAC address device filtering on the wireless LAN can be activated and configured to allow exclusive association or deny association with the access point. To use MAC address filtering, click to select the Activated option and specify the MAC addresses allowed or denied association in the entry fields provided. Up to 8 MAC addresses can be added to the list. Select the action to be performed on the MAC addresses in the list. Choose Allow Association to allow association to only the MAC address listed. This option will filter or deny association to any device not listed. Alternatively the Deny Association option will deny association to only the MAC addresses listed. Click SAVE to apply and save the new filtering rules. MAC address filtering can be Deactivated at any time, the MAC addresses in the list remain until they are deleted by the administrator. A MAC address on the list can be removed by highlighting it with cursor, pressing the Delete key on your keyboard and pressing SAVE. D-Link DSL-2640R User Manual 30 Section 3 Configuration Advanced Setup The Advanced Setup folder contains windows for Routing, NAT and ADSL. Firewall This menu allows the Router to enforce specific policies intended to protect the private network against certain types of attacks. To enable the firewall feature, select the Enabled option and click SAVE. To enable the Stateful Packet Inspection feature, select the Enabled option and click SAVE. Routing Use Static Routing to specify a route used for data traffic within your Ethernet LAN or to route data on the WAN. This specifies that all packets destined for a particular network or subnet use a predetermined gateway. To add a static route to a specific destination IP on the local network, click the ADD ROUTE button to view the setup window. D-Link DSL-2640R User Manual 31 Section 3 Configuration To add a static route to a specific destination IP on the local network, enter a Destination IP Address, select a suitable IP Subnet Mask, and type in the Gateway IP Address. Click SAVE to enter the new static route in the table below. The route becomes active immediately upon creation. The Metric field determines the number of hops or routers that will be allowed to route traffic. NAT The Router features include policy-based Network Address Translation (NAT) for greater flexiblity and control of NAT functions. The user can customize port mapping for a single global IP address or full feature NAT support for mapping multiple global IP addresses to servers or clients on the LAN. Single User Account (SUA) NAT is enabled by default. Using the default settings, NAT will function for Routed connections without any additional configuration. NAT is disabled automatically when the device is operating in pure Bridge mode. To customize NAT settings for IP address mapping, use the NAT window located in the Advanced Setup directory. D-Link DSL-2640R User Manual 32 Section 3 Configuration Note that if the NAT Status in the window above indicates Deactivated, the user must first activate NAT on the Internet menu. Click SAVE and the window above will appear. The IP Address Mapping

(for Multiple IP Service) link only appears when the Multiple option is selected under Number of IPs. DMZ Since some applications are not compatible with NAT, the Router supports use of a DMZ IP address for a single host on the LAN. This IP address is not protected by NAT and will therefore be visible to agents on the Internet with the right type of software. Keep in mind that any client PC in the DMZ will be exposed to various types of security risks. If you use the DMZ, take measures (such as client-based virus protection) to protect the remaining client PCs on your LAN from possible contamination through the DMZ. To designate a DMZ IP address, select the Enabled radio button, type in the DMZ Host P Address of the server or device on your LAN, and click the SAVE button. To remove DMZ status from the designated IP address, select the Disabled radio button and click SAVE. It will be necessary to save the settings and reboot the Router before the DMZ is activated. D-Link DSL-2640R User Manual 33 Section 3 Configuration Virtual Server To customize inbound port mapping of NAT for a Single User Account using one global IP address, select the Single option under Number of IPs and click the Virtual Server link. By default, NAT will map all ports according to the traditional IP NAT protocol. However, the user may opt to map specific ports or a range of ports to a specified IP address on the LAN. It is also possible to map all ports to a specified LAN IP address. You will use this same window if you are using NAT for a multiple number of IPs. To specify NAT mapping, type in the port or range of ports used for mapping in the Start Port Number and End Port Number columns and enter the LAN Local IP Address of the server or system used for the selected ports. To map a single port, type the port number in both Start and End port entry fields. Click the SAVE button to apply the NAT port mapping and save the settings. D-Link DSL-2640R User Manual 34 Section 3 Configuration IP Address Mapping The Router allows the user to setup policies used for inbound or outbound port mapping to one or multiple global IP addresses. This may be desirable on networks that maintain multiple global IP addresses, multiple virtual connections or where servers on the network must respond to connection requests from the WAN. To configure the mapping rules, select the select the Multiple option under Number of IPs on the NAT menu and click the IP Address Mapping (for Multiple IP Service) link. To edit a rule, use the Rule Index drop-down menu. One you have made the desired changes, click the SAVE button. Rule Types:

One-to-One Many-to-One Many-to-Many No Overload D-Link DSL-2640R User Manual Use this for mapping a single global IP address to a single private internal IP address. In this case, IP mapping is done for both inbound and outbound traffic. This is essentially the same as SUA NAT. Multiple private internal IP addresses are mapped to a single global IP address. Mapping occurs for outbound traffic. Many-to-Many Overload In this case, IP mapping is done for outbound traffic from multiple private internal IP addresses to a shared pool of multiple global IP addresses. IP mapping is also done for outbound traffic from multiple private internal IP addresses to a pool of global IP addresses, however each internal IP address will connect to a single global IP address from the pool. In other words each available global IP address is allowed connection to only one internal IP address at a time. 35 Section 3 Configuration QoS Quality of Service or QoS assigns a priority level to data packets to make sure time sensitive network applications operate smoothly with minimal delay. QoS enables applications such as VoIP (voice-over Internet Protocol) or video conferencing to function well on networks that may have multiple simultaneous transmissions of many types of data. Since much of the traffic is not significantly affected by slight transmission delay, QoS is used to give preference to traffic that is affected by delay. QoS implementation on the Router instead uses four queues that can be mapped to and assigned priority. QoS protocols supported on the Router include IEEE 802.1p, Differentiated Services Code Point (DiffServ) weighted scheduling, IP Type of Service (IP ToS) as well as application specific and VLAN Group QoS mapping. To implement QoS on the Router, select the preferred protocol used for QoS and map the priority scheduling used to the four queues used on the Router. To enable QoS, select the QoS: Activated option, and select the type of QoS mapping used. Use Queue #1 for the lowest priority traffic, and Queue #4 for the highest priority traffic. D-Link DSL-2640R User Manual 36 Section 3 Configuration 802.1p IP QoS To implement QoS mapping for IEEE 802.1p priority, select the Activated option and configure mapping for the 8 priority levels defined by 802.1p priority. 802.1p user priority 0 is the lowest priority while 7 is the highest. To implement QoS mapping for IP QoS, select the Activated option and configure mapping for one of two types of IP QoS, IP ToS (Type of Service) or DiffServ:

IP ToS assigns 0 for the lowest priority and 7 for the highest.

DiffServ uses 64 levels with 0 being the lowest, 63 the highest. DiffServ QoS mapping requires mapping for all 64 levels. If a level is not mapped a popup box informs the user that the level has not been assigned. Application QoS To implement Application QoS mapping, select the Activated option and configure queue assignment for applications. The VLAN Group QoS default applications mapping for voice and video applications set the highest priority for voice and second highest for video. The queue assignment and RTP port ranges may be changed if desired. Queues may also be assigned for IGMP packets and general data packets (i.e. all other traffic). To implement VLAN Group QoS mapping, select the Activated option and configure mapping for VLAN groups using the VLAN group identification number (VID) for queue mapping. This can be used together with VLAN assignment for different virtual connections (PVCs) for QoS mapping to the PVCs. See below for more information on how VLANs can be used on the Router. D-Link DSL-2640R User Manual 37 Section 3 Configuration VLAN The Router supports port-based VLANs to segment the Ethernet LAN and/or map 802.1Q VLAN groups to different PVCs. VLANs are grouped according to physical Ethernet port or by PVC for users running multiple connections on the WAN. To use VLANs select the Activated option, then open a separate menu to Assign VLAN PVID for Each Interface. When multiple connections are used on the WAN, this is especially useful to assign VLAN user groups to specified PVCs. The Define VLAN Group menu is used to set up VLAN user groups and implement VLAN taqging. D-Link DSL-2640R User Manual 38 Section 3 Configuration Assign PVID Enter the desired PVID values in the menu and then click the SAVE button. PVIDs assignment can be used to create port-based VLANs for any of the four Ethernet ports; or use the PVID to map VLANs to separate PVCs. The eight PVCs are labeled ATM VC # 1, VC # 2 and so on up to VC # 7 for the purpose of VLAN to PVC mapping. D-Link DSL-2640R User Manual 39 Section 3 Configuration VLAN To define a VLAN group, click Define VLAN Group in the VLAN menu to access the VLAN Group Setting menu. Make the desired VLAN Group assignment and tagging settings in the window above and then click the SAVE button. Up to eight VLAN groups may be created. Click to select the Ethernet Port and ATM VCs Port for each VLAN member port. Any port may be specified as Tagged. Packets that are tagged (are carrying the 802.1Q VID information) can be transmitted from one 802.1Q compliant network device to another with the VLAN information intact. This allows 802.1Q VLANs to span network devices (and indeed, the entire network, if all network devices are 802.1Q compliant). Select the Tagged option to enable tagging for the port. Ports with tagging enabled will put the VID number, priority and other VLAN information into the header of all packets that flow into and out of it. If a packet has previously been tagged, the port will not alter the packet, thus keeping the VLAN information intact. Other 802.1Q compliant devices on the network to make packet-forwarding decisions can then use the VLAN information in the tag. D-Link DSL-2640R User Manual 40 Section 3 Configuration ADSL This menu allows the user to set the configuration for ADSL protocols. For most ADSL accounts the default settings will work. This configuration works with all ADSL implementations. If you have been given instructions to change the ADSL Mode or ADSL Type, select the desired option from the drop-down menus and click the SAVE button. D-Link DSL-2640R User Manual 41 Section 3 Configuration Access Management The Access Management directory contains links for the ACL, Filter, SNMP, UPnP, and DDNS menus. ACL Access Control on the Router is an IP-based and/or application-based filtering mechanism used for security and efficiency. Add rules to the list that specify IP address or IP address range. For each rule, a network application can be specified. The Interface effected can be specific to the LAN, WAN or Both. Click the SAVE button to apply and save the new rule. Each rule must be indexed and can be Active or not while remaining on the list. The entire Access Control List can be Activated or Deactivated without change the list. D-Link DSL-2640R User Manual 42 Section 3 Configuration Filter Menus The filtering functions on the Router are based on IP address, MAC address, URL or common network applications. Choose the type of filtering to configure and enter the criteria appropriate for that type of filtering. Each menu presents settings specific to the type. IP and MAC based filtering rules can be applied sequentially so that each rule has the option of forwarding packets that do not match the rule, or going to the next rule on the list for further scrutiny. IP/MAC Based Filter IP and MAC based filters are indexed by rule set and again by individual rule in the set. Choose IP or MAC based filtering options and click the SAVE button to add the new rule to the list. To remove a rule set from the list, select it and click on the Delete button. The Rule Unmatched option determines whether to Forward a packet or go to Next rule on the list. Each set applies the rules in the set sequentially in the order they are listed (or indexed). D-Link DSL-2640R User Manual 43 Section 3 Configuration Application Filter The Application Filter is a simple filter that drops all incoming packets for the selected applications from the Internet. Choose the applications to Allow or Deny from those listed and click the SAVE button to apply and save the application filtering rule. The application filter can be Activated or Deactivated at any time without changing the selected options. D-Link DSL-2640R User Manual 44 Section 3 Configuration The URL Filter will deny access to any URL entered in the list. Up to 16 URLs can be specified. The URL Filter can be Active or not without changing the entries on the list. Select an index number for a new URL to be added to the list, type the URL and click the SAVE button to add it to the list. Remove a URL from the list by choosing the index number for the URL to be removed and clicking on the Delete button. D-Link DSL-2640R User Manual 45 Section 3 Configuration SNMP Simple Network Management Protocol is a standard for internetwork and intranetwork management. Enter the desired information in the Get Community and Set Community fields and then click the SAVE button when you are finished with your SNMP settings. UPnP UPnP supports zero-configuration networking and automatic discovery for many types of networked devices. When enabled, it allows other devices that support UPnP to dynamically join a network, obtain an IP address, convey its capabilities, and learn about the presence and capabilities of other devices. DHCP and DNS service can also be used if available on the network. UPnP also allows supported devices to leave a network automatically without adverse effects to the device or other devices on the network. Diverse networking media including Ethernet, Firewire, phone line, and power line networking can support UPnP. To enable UPnP for any available connection, click Activated, and click the SAVE button. You can also opt to allow user to make configuration changes through UPnP by selecting Activated under the Auto-configured setting. D-Link DSL-2640R User Manual 46 Section 3 Configuration DDNS The Router supports Dynamic Domain Name Service or Dynamic DNS. Dynamic DNS is used for account that may not have a permanent fixed global IP address for servers or other resources that are accessed through the Internet. It allows the user to alias a dynamic IP address to a fixed host name. To configure Dynamic DNS:

1. Click the Activated box to select it. 2. Enter the full host and domain name used for your Dynamic DNS under My Host Name. 3.

200MHz 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 Click'n Connect Utility D-Link DSL-2640R User Manual 1 Section 1 - Product Overview 11 Features PPP (Point-to-Point Protocol) Security The DSL-2640R 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-2640R 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-2640R supports TCP/IP protocol, the language used for the Internet. It is compatible with access servers manufactured by major vendors. RIP-1/RIP-2 The DSL-2640R 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). 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 Full Network Management The DSL-2640R incorporates SNMP (Simple Network Management Protocol) support for web-based Quality of Service for ATM data transfer. management and text-based network management. Easy Installation The DSL-2640R 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-2640R User Manual 4 Section 2 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. Before You Begin 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. 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-2640R 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. D-Link DSL-2640R User Manual 5 Section 2 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 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-2640R User Manual 6 Section 2 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/PPoA (PPPoE LLC, PPPoA LLC or PPPoA VC-Mux) Dynamic IP Address (1483 Bridged IP LLC, 1483 Bridged IP VC-Mux, 1483 Routed IP LLC(IPoA) or 1483 Routed 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 (ADSL2+ Multi-Mode) 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. D-Link DSL-2640R User Manual 7 Section 2 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 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. 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. Information you will need about DSL-2640R Username This is the Username needed 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 1234. The user may change this. LAN IP addresses for the DSL-2640R 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 192.168.1.1. 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-2640R This is the subnet mask used by the DSL-2640R, and will be used throughout your LAN. The default subnet mask is 255.255.255.0. This can be changed later. D-Link DSL-2640R User Manual 8 Section 2 Installation Information you will need about your LAN or computer:

Ethernet NIC If your computer has an Ethernet NIC, you can connect the DSL-2640R to this Ethernet port using an Ethernet cable. You can also use the Ethernet ports on the DSL-2640R to connect to other computer or Ethernet devices. DHCP Client status Your DSL-2640R 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-2640R will assign are from 192.168.1.2 to 192.168.1.254. 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-2640R ADSL Router. 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. D-Link DSL-2640R User Manual 9 Section 2 Installation The Router must be used with the power adapter included with the device. Power on Router 1. Connect the power adapter to the Power Input (12V AC 1.2A) 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 toggle 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. Press and hold the reset button while the device is powered off. 2. Turn on the power. 3. Wait for 5~8 seconds and then release the reset button. Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings. The device settings will be restored to the factory default IP address 192.168.1.1 and the subnet mask is 255.255.255.0, the default management Username is admin and the default Password is admin. D-Link DSL-2640R User Manual 10 Section 2 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 10BASE-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-2640R User Manual 11 Section 3 Configuration Setup This section will show you how to set up and configure your new D-Link Router using the Web-based configuration utility. Web-based Configuration Utility Connect to the Router To configure the WAN connection used by the Router it is first necessary to communicate with the Router through its management interface, which is HTML-based and can be accessed using a web browser.

When you are satisfied that all the Internet settings are configured correctly, click on the SAVE button. D-Link DSL-2640R User Manual When PPPoE or PPPoA is used, the Router becomes the PPP client, that is, all the software needed to establish and maintain the connection is located on the Router. ISPs frequently require PPP client software to be installed on workstations. If any computers have PPP client software installed on them, this software must be removed or at least disabled before the computers are able to connect to the Internet through the Router. If you are required to provide a User Name and Password every time you access the Internet, your computer may have PPP client software installed on it. 21 A Dynamic IP Address connection configures the Router to automatically obtain its global IP address from a DHCP server on the ISPs network. The service provider assigns a global IP address from a pool of addresses available to the service provider. Typically the IP address assigned has a long lease time, so it will likely be the same address each time the Router requests an IP address. Section 3 Configuration Dynamic IP Address To configure a Dynamic IP Address WAN connection, follow these steps:

3. 1. Choose the Connection Type from the drop-down menu. This defines both the connection protocol and encapsulation method used for your ADSL service. The available options are 1483 Bridged IP LLC and 1483 Bridged IP VC-Mux. If you have not been provided specific information for the Connection Type setting, leave the default setting. 2. Some ISPs record the unique MAC Address of your computers Ethernet adapter when you first access their network. This can prevent the Router (which has a different MAC address) from being allowed access to the ISPs network

(and the Internet). To clone the MAC address of your computers Ethernet adapter, click the Copy Your PCs MAC Address button. If you are instructed to change the VPI or VCI values, type in the values assigned for your account. 4. When you are satisfied that all the WAN settings are configured correctly, click the Apply Settings button. This will save the settings and reboot the Router to let your changes take effect. 5. Upon restarting, the Router should automatically establish the WAN connection. If it does not, click the Connect button at the bottom of this window. 6.

If this is the first time you are setting up the ADSL connection it is recommended that you leave the settings at the default values until you have established the connection. Please see the table on ATM QoS that directly follows the PPPoA/PPPoE section of this manual for further information. In the Static IP section, choose the Encapsulation setting from the pull-down menu. This defines the encapsulation method used for your ADSL service. The available options are 1483 Bridged IP LLC, 1483 Bridged IP VC-Mux, 1483 Routed IP LLC (IPOA), and 1483 Routed IP VC-Mux. If you have not been provided specific information for this section, leave the default setting. 5. Change the Static IP Address, IP Subnet Mask, and Gateway IP address as instructed by your ISP. These are the global IP settings for the Internet (WAN) interface. This is the visible IP address of your account. Your ISP should have provided these IP settings to you. 6. NAT should remain enabled. If you disable NAT, you will not be able to use more than one computer for Internet connections. NAT is enabled and disabled system-wide, therefore if you are using multiple virtual connections, NAT will disabled on all connections. 7. Turn on the Default Route feature if you want to use the Router as the default route to the Internet for your LAN. Whenever a computer on the LAN attempts to access the Internet, the Router becomes the Internet gateway to the computer. If you have an alternative route for Internet traffic you may turn this off without effecting the Routers connection. 8. Leave the TCP MTU Option value at the default setting unless you have specific reasons 9. Select the desired Dynamic Route from RIP1, RIP2-B, or RIP2-M. Next, set the Direction to Both, IN Only, OUT Only, or None. 10. The Multicast feature is Disabled by default. Toggle between IGMP v1 and IGMP v2. 11. When you are satisfied that all the Internet settings are configured correctly, click on the to change this. SAVE button. When the Router is configured to use Static IP Address assignment for the Internet (WAN) connection, you must manually assign a global IP Address, Subnet Mask and Gateway IP Address used for the WAN connection. Follow the instruction below to configure the Router to use Static IP Address assignment for the WAN connection. D-Link DSL-2640R User Manual 23 Bridge Mode Section 3 Configuration Follow the instructions below to configure a Bridged connection for the Internet interface. 1. Choose the Bridge Mode option under ISP in the Encapsulation section. 2. The settings in the ATM VC section at the top of the window should not be changed unless you have been instructed to change them. However, if you are instructed to change the VPI or VCI values, type in the values assigned for your account. Leave the Virtual Circuit and Status settings at the defaults (Pcv0 and Activated) values for now. This can be used later if you are configuring multiple virtual circuits for your ADSL service. 3. Most users will not need to change QoS settings. If this is the first time you are setting up the ADSL connection, it is recommended that you leave the settings at the default values until you have established the connection. Please see the table on ATM QoS that directly follows the PPPoA/PPPoE section of this manual for further information. In the Bridge Mode section, choose the Encapsulation setting from the pull-down menu. This defines the encapsulation method used for your ADSL service. The available options are 1483 Bridged IP LLC and 1483 Bridged IP VC-Mux. If you have not been provided specific information for this section, leave the default setting. 4. For Bridged connections it will be necessary for most users to install additional software on any computer that will the Router for Internet access. The additional software is used for the purpose of identifying and verifying your account, and then granting Internet access to the computer requesting the connection. The connection software requires the user to enter the User Name and Password for the ISP account. This information is stored on the computer, not in the Router. 5. When you are satisfied that all the Internet settings are configured correctly, click on the SAVE button. D-Link DSL-2640R User Manual 24 Section 3 Configuration LAN Setup To access the LAN window, click the LAN button in the Interface Setup directory. You can configure the LAN IP address to suit your preference. Many users will find it convenient to use the default settings together with DHCP service to manage the IP settings for their private network. The IP address of the Router is the base address used for DHCP. In order to use the Router for DHCP on your LAN, the IP address pool used for DHCP must be compatible with the IP address of the Router. The IP addresses available in the DHCP IP address pool will change automatically if you change the IP address of the Router. To configure the LAN IP address, type in the desired values and click the SAVE button. Your web browser should automatically be redirected to the new IP address. You will be asked to login to the Routers web manager again. The DHCP server is enabled by default for the Routers Ethernet LAN interface. DHCP service will supply IP settings to workstations configured to automatically obtain IP settings that are connected to the Router though the Ethernet port. When the Router is used for DHCP it becomes the default gateway for DHCP client connected to it. Keep in mind that if you change the IP address of the Router the range of IP addresses in the pool used for DHCP on the LAN will also be changed. The IP address pool can be up to 253 IP addresses. The three options for DHCP service are as follows:

Use the Router as a DHCP server for your LAN.

Disable DHCP service and manually configure IP settings for workstations.

Use DHCP service provided by your ISP. D-Link DSL-2640R User Manual 25 Section 3 Configuration Use the Router for DHCP To use the built-in DHCP server, click the DHCP radio button to Enabled if it has not already selected. The IP Address Pool settings can be adjusted. The Starting IP Address is the lowest available IP address (default = 192.168.1.2). If you change the IP address of the Router, this will change automatically to be 1 more that the IP address of the Router. Type in the Lease Time in the entry field provided. This is the amount of time in seconds that a workstation is allowed to reserve an IP address in the pool if the workstation is disconnected from the network or powered off. You may also configure DNS settings for the LAN when using the Router in DHCP mode. Toggle the DNS Relay setting to Use User Discovered DNS Server Only from Use Auto Discovered DNS Server Only and enter the IP addresses for the Primary DNS Server and Secondary DNS Server in the field provided. The manually configured DNS settings will be supplied to clients that are configured to request them from the Router. Disable the DHCP Server To disable DHCP, select the Disabled option and click on the SAVE button. Choosing this option requires that workstations on the local network must be configured manually or use another DHCP server to obtain IP settings. If you configure IP settings manually, make sure to use IP addresses in the subnet of the Router. You will need to use the Routers IP address as the Default Gateway for workstations in order to provide Internet access. Use DHCP Relay To use DHCP service from your ISP or another DHCP server, select the Relay option and type the DHCP Server IP for Relay Agent address in the space provided. Click SAVE to begin DHCP relay from the ISP. D-Link DSL-2640R User Manual 26 Wireless Setup Section 3 Configuration The two essential settings for wireless LAN operation are the SSID and Channel Number. The SSID (Service Set Identifier) is used to identify a group of wireless LAN components. The SSID can be broadcast in order to allow properly configured wireless stations to learn the SSID and join the group. Wireless LAN is enabled by default on the Router. If the wireless access point has been previously disabled you can enable 802.11g Wireless LAN operation by selecting the Activated option for Wireless LAN and continue to configure basic settings. Click the SAVE button to begin wireless LAN function with the settings as configured. It is not necessary to reboot the Router. D-Link DSL-2640R User Manual 27
