Click Yes to remove the static route, or click No to keep the setting. Configuring Other Routers on Your LAN It is essential that all IP packets for devices that are not on the local LAN can be passed to the Router, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN must be configured to use the Router as the default route or default gateway. Local Router The local router is the Router installed on the same LAN segment as the Router. This router requires that the default route is the Router itself. Typically, routers have a special entry for the default route. It should be configured as follows. Destination: Normally 0.0.0.0 but check your router documentation. Subnet Mask: Normally 0.0.0.0 but check your router documentation. Gateway: The IP Address of the Router. Other Routers on the Local LAN Other routers on the local LAN must use the Router’s Local Router as the Default Route. The entries will be the same as the Router’s local router, with the exception of the Gateway IP Address.  For a router with a direct connection to the Router’s local Router, the Gateway IP Address is the address of the Router’s local router.
Chapter 5:Connection Mode 61 For routers which must forward packets to another router before reaching the Router’s local router, the Gateway IP Address is the address of the intermediate router. Example – Static Route Here provides you an example of Static Route. For the Router’s Routing Table For the LAN shown above, with 2 routers and 3 LAN segments, the Router requires to add 2 static routes as follows: ADSL Router Destination 192.168.10.0 Subnet Mask 255.255.255.0 (Standard Class C) Gateway 192.168.1.254 (Router B) IP Routing – Dynamic Routing Routing Information Protocol (RIP) is utilized as a means of exchanging routing information between routers. It helps the routers to determine optimal routes. This page allows you to enable/disable this function. RIP Version: It incorporates the RIP information when receiving and broadcasting the RIP packets. From the drop down list, select a RIP version to be accepted, 1, 2 or both. Operation Mode: There are two modes for you to choose, Active and Passive. Select Active for transmitting and receiving data, or select Passive for receiving data only. Enabled: Click Enabled to enable the RIP function on different interface. Otherwise, disable this function. Click Apply to invoke the settings set here.
ADSL Router User Manual 62 Virtual Servers-Port Forwarding The Router implements NAT to let your entire local network appear as a single machine to the Internet. The typical situation is that you have local servers for different services and you want to make them publicly accessible. With NAT applied, it will translate the internal IP addresses of these servers to a single IP address that is unique on the Internet. NAT function not only eliminates the need for multiple public IP addresses but also provides a measure of security for your LAN. When the router receives an incoming IP packet requesting for access to your local server, the router will recognize the service type according to the port number in this packet (e.g., port 80 indicates HTTP service and port 21 indicates FTP service). By specifying the port number, you tell the router which service should be forwarded to the local IP address you specify. After you setting the virtual server you should modify the filter rule whichever port and service you set on virtual server. Because the firewall has protect the route by filter rule so that you should update the filter rule after you set up virtual server. Virtual Server allows you to make servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because:  Your server does not have a valid external IP Address.  Attempts to connect to devices on your LAN are blocked by the firewall in this device. The Virtual Server feature solves these problems and allows Internet users to connect to your servers, as illustrated below:
Chapter 5:Connection Mode 63IP Address seen by Internet Users Please note that, in the above picture, both Internet users are connecting to the same IP address, but using different protocols. To Internet users, all virtual servers on your LAN have the same IP Address. This IP Address is allocated by your ISP. This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers. However, you can use Dynamic DNS feature to allow users to connect to your virtual servers by using a URL, instead of an IP address. To set a virtual server, please open the Virtual Servers item from the Advanced Setup - NAT menu. Add New Port Forwarding To add a new Port Forwarding, please click Add from the Port Forwarding web page. Pre-defined Choose one of the services type from the first drop down list, such as Audio/Video, Games and so on. In the second drop down list, choose the name of the application that you want to use with the type that you select in the first list. User defined: Type a new service name for building a customized service for specific reason.
ADSL Router User Manual 64 From Internet Host IP Address: Select the initial place for port forwarding. If you choose SINGLE, a box will appear for you to fill in the IP address for the specific host. And, if you choose SUBNET, the boxes of IP and Subnet will appear for you to fill in the IP address and subnet mask for the specific host as the start point. Forwarded to Internet Host IP Address: Type in the address for the host used as the place that information will be forwarded. IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the router redirects the external service request to the appropriate server (located at another internal IP address). After adding a new virtual server, click Apply. The following screen will be shown to display the status for new ones. If you do not want the new server that you added, please check the Delete box of that one and click the Delete button to discard it.Or if you want to add another one again, click Add to add a new one. Connecting to the Virtual Servers Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the Internet IP Address (the IP Address allocated to you by your ISP.) For example, Http://203.70.212.52 Ftp://203.70.212.52 It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. However, you can use the Dynamic DNS feature to allow users to connect to your Virtual Server through a URL, rather than an IP Address. Virtual Servers-Port Triggering When the router detects outbound traffic on a specific port, it will set up the port forwarding rules temporarily on the port ranges that you specify to allow inbound traffic. It is supposed to increase the support for Internet gaming, video conferencing, and Internet telephony due to the applications require multiple connection. To add a new port triggering, click Add to open this web page. Than choose an application name from the Pre-defined list box. The system provides 9 items for your choice.

Chapter 5:Connection Mode 67Firewall The firewall is a software that interrupts the data between the Internet and your computer. It is the TCP/IP equivalent of a security gate at the entrance to your company. All data must pass through it, and the firewall (functions as a security guard) will allow only authorized data to be passed into the LAN. What the firewall can do? It can:  deny or permit any packet from passing through explicitly  distinguish between various interfaces and match on the following fields:  source and destination IP address  port To keep track of the performance of IP Filter, a logging device is used which supports logging of the TCP/UDP and IP packet headers and the first 129 bytes of the packet (including headers) when a packet is successfully passed through, a packet is blocked from passing through and it matches a rule setup to look for suspicious packets Filtering by IP address An example for firewall setup: This picture is the most common and easiest way to employ the firewall. Basically, you can install a packet-filtering router at the Internet gateway and then configures the filter rule in the router to block or filter protocols and addresses. The systems behind the router usually have a direct access to the Internet, however some dangerous services such as NIS and NFS are usually blocked. For the security of your router, set the firewall is an important issue. Choose Disabled to disable the firewall function. Click Enabled to invoke the settings that you set in this web page.

Different item leads different web page settings. Please read the following information carefully. For WPA Disabled For Wiresless Security Disabled Wireless Security: The Disabled item offers you the less protection for wireless communication. If you choose Disabled, the Encryption Keys will not be shown on this page. For 64-Bit WEP Wireless Security: Select the WEP mode for the WEP key function. You can choose 64-bit or 128-bit for your necessity. If selected, data is encrypted using the key before being transmitted. For example, if you set 64-bit in this field, then the receiving station must be set to use 64 Bit Encryption, and have the same Key value too. Otherwise, it will not be able to decrypt the data. Please choose 64-Bit WEP for this page. Authentication Type: The ADSL Router supports two authentication types: Open System and Shared key. This should be considered with the WEP (Wired Equivalent Privacy) mechanism. Open System means that it allows any client to authenticate and attempt to communicate with a bridge. The client can only communicate if its WEP keys match the router’s WEP keys.
ADSL Router User Manual 76 Shared Key means that a bridge or router will send an unencrypted text string to any client attempting to communicate with the router. The client requesting authentication encrypts the text and sends back to the router. Both unencrypted and encrypted can be monitored, yet it leaves the bridge open to attack from any intruder if he calculates the WEP key by comparing the text strings That is why shared key authentication can be less secure than open authentication. Format: Choose the typing method of encryption key. You have to click either Hexadecimal digits or ASCII characters and type the keys on the fields of Key 1 to Key 4. Key 1 to 4: Type the encryption key length and fill out WEP keys. For 64-bit WEP mode, the number you can type is that 5 characters or 10 hexadecimal digits.

Chapter 5:Connection Mode 89SNMP Setting The SNMP, the abbreviation of Simple Network Management Protocol, is used to refer to a collection of specifications for network management that include the protocol itself, the definition of data structures and associated concepts. A management station performs the monitoring function by retrieving the value of MIB objects. The management station and agents are linked by a network management protocol that is SNMP. The SNMP includes three key capabilities, get, set and trap. A single management station can handle many agents as long as SNMP remains relatively “simple”, so the number can be high (hundreds or so). The following picture is the typical configuration of protocols for SNMP. As for a stand-alone management station, a manager process controls access to a central MIB at the management station and provides an interface to the network manager. The manager process achieves network management by using SNMP, which will be implemented on top of the UDP, IP and the relevant network-dependent protocols (e.g., Ethernet). For an agent device that supports other applications, such as FTP, both TCP and UDP are required. An agent may issue a trap message in response to an event that effects the MIB and the underlying managed resources. Note: There are no ongoing connections are maintained between a management station and its agents. Instead, each exchange is a separate transaction between a management station and an agent. Each agent is responsible for notifying the management station of any unusual event; for example, if the agent crashes and is rebooted, a link fails or an overload condition as defined by the packet load crosses some threshold. These events are communicated in SNMP messages known as traps. Please select the SNMP menu from Management. The dialog will appear. SNMP Agent: Choose Disable to close this function; choose Enabled to open this function. Read Community: The default setting is public, please type in the data that your ISP provided.

Chapter 5:Troubleshooting 93Chapter 5: Troubleshooting If the suggested solutions in this section do not resolve your issue, contact your system administrator or Internet service provider. Problems with LAN PCs on the LAN cannot get IP addresses from the ADSL Router. The chances are that the interface used as DHCP server is modified and the client PCs do not renew IP addresses. If your DHCP server is enabled on Private IP Address previously and you modify the interface to Public IP Address, the client PCs should renew IP addresses. The PC on the LAN cannot access the Web page of the ADSL Router. Check that your PC is on the same subnet with the ADSL Router. The virtual server can’t be access after setting virtual server. Check the filter rule of the port that virtual server service setting for example, the virtual server service set FTP 21 you need update the filter rule of the ftp 21 Direction setting: Choose filter the packets that incoming action (In Bound) are Allow on the interface. Problems with WAN You cannot access the Internet.  Check the physical connection between the ADSL Router and the LAN. If the LAN LED on the front panel is off or keeps blinking, there may be problem on the cable connecting to the ADSL Router. At the DOS prompt, ping the IP address of the ADSL Router, e.g, ping 192.168.1.1. If the following response occurs: Relay from 192.168.1.1 bytes=32 time=100ms TTL=253 Then the connection between the ADSL Router and the network is OK. If you get a failed ping with the response of: Request time out Then the connection is fail. Check the cable between the ADSL Router and the network.  Check the DNS setting of the ADSL Router. At the DOS prompt, ping the IP address of the DNS provided by your ISP. For example, if your DNS IP is 168.95.1.1, then ping 168.95.1.1. If the following response occurs: Relay from 168.95.1.1 bytes=32 time=100ms TTL=253 Then the connection to the DNS is OK. If you get a failed ping with the response of:
ADSL Router User Manual 94 Request time out Then the DNS is not reachable. Check your DNS setting on the ADSL Router. Problems with Upgrading The following lists the error messages that you may see during upgrading and the action to take.  Error: All the ADSL LEDs light up and cannot light off as usual. Possible cause: When users execute firmware upgrade and save settings to the router, the power for the router is lost for some unknown reasons, the normal web page for the router might be damaged. After power on your router, the LEDs might not work normally. Action: Use the browser to connect to the router for executing image upgrade.  Error Message: Image uploading failed. The selected file contains an illegal image. Possible cause: The firmware file format is invalid. Action: Check the file format is correct, otherwise download a firmware file with correct format.  Error Message: Image uploading failed. The system is out of memory. Possible cause: It may be caused by the lack of memory. Action: Reboot your ADSL Router and perform the upgrade task again.  Error Message: Image uploading failed. No image file was selected. Possible cause: You did not select a file correctly. Action: Download a compatible firmware from the web.
Chapter 6: Glossary 95Chapter 6: Glossary ARP (Address Resolution Protocol ) ARP is a TCP/IP protocol for mapping an IP address to a physical machine address that is recognized in the local network, such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address. Inverse ARP (In-ARP), on the other hand, is used by a host to discover its IP address. In this case, the host broadcasts its physical address and a RARP server replies with the host's IP address. DHCP (Dynamic Host Configuration Protocol) When operates as a DHCP server, the ADSL Router assign IP addresses to the client PCs on the LAN. The client PCs “leases” these Private IP addresses for a user-defined amount of time. After the lease time expires, the private IP address is made available for assigning to other network devices. The DHCP IP address can be a single, fixed public IP address, an ISP assigned public IP address, or a private IP address. If you enable DHCP server on a private IP address, a public IP address will have to be assigned to the NAT IP address, and NAT has to be enabled so that the DHCP IP address can be translated into a public IP address. By this, the client PCs are able to access the Internet. LAN (Local Area Network) & WAN (Wide Area Network) A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. A WAN, on the other hand, is an outside connection to another network or the Internet. The Ethernet side of the ADSL Router is called the LAN port. It is a twisted-pair Ethernet 10Base-T interface. A hub can be connected to the LAN port. More than one computers, such as server or printer, can be connected through this hub to the ADSL Router and composes a LAN. The DSL port of the ADSL Router composes the WAN interface, which supports PPP or RFC 1483 connecting to another remote DSL device. NAT (Network Address Translation) IP Address NAT is an Internet standard that translates a private IP within one network to a public IP address, either a static or dynamic one. NAT provides a type of firewall by hiding internal IP addresses. It also enables a company to use more internal IP addresses. If the IP addresses given by your ISP are not enough for each PC on the LAN and the ADSL Router, you need to use NAT. With NAT, you make up a private IP network for the LAN and assign an IP address from that network to each PC. One of some public addresses is
ADSL Router User Manual 96 configured and mapped to a private workstation address when accesses are made through the gateway to a public network. For example, the ADSL Router is assigned with the public IP address of 168.111.2.1. With NAT enabled, it creates a Virtual LAN. Each PC on the Virtual LAN is assigned with a private IP address with default value of 192.168.1.2 to 192.168.2.254. These PCs are not accessible by the outside world but they can communicate with the outside world through the public IP 168.111.2.1. Private IP Address Private IP addresses are also LAN IP addresses, but are considered “illegal” IP addresses to the Internet. They are private to an enterprise while still permitting full network layer connectivity between all hosts inside an enterprise as well as all public hosts of different enterprises. The ADSL Router uses private IP addresses by assigning them to the LAN that cannot be directly accessed by the Internet or remote server. To access the Internet, private network should have an agent to translate the private IP address to public IP address. Public IP Address Public IP addresses are LAN IP addresses that can be considered “legal” for the Internet, because they can be recognized and accessed by any device on the other side of the DSL connection. In most cases they are allocated by your ISP. If you are given a range of fixed IP addresses, then one can be assigned to the router and the others to network devices on the LAN, such as computer workstations, ftp servers, and web servers. PVC (Permanent Virtual Circuit) A PVC is a logical point-to-point circuit between customer sites. PVCs are low-delay circuits because routing decisions do not need to be made along the way. Permanent means that the circuit is preprogrammed by the carrier as a path through the network. It does not need to be set up or turned down for each session. RIP (Routing Information Protocol) RIP is a routing protocol that uses the distance-vector routing algorithms to calculate least-hops routes to a destination. It is used on the Internet and is common in the NetWare environment. It exchanges routing information with other routers. It includes V1, V2 and V1&V2, which controls the sending and receiving of RIP packets over Ethernet. UDP (User Datagram Protocol) UDP is a connectionless transport service that dispenses with the reliability services provided by TCP. UDP gives applications a direct interface with IP and the ability to address a particular application process running on a host via a port number without setting up a connection session. Virtual Server You can designate virtual servers, e.g., a FTP, web, telnet or mail server, on your local network and make them accessible to the outside world. A virtual server means that it is not a dedicated server -- that is, the entire computer is not dedicated to running on the public network but in the private network. VPI (Virtual Path Identifier) & VCI (Virtual Channel Identifier) A VPI is a 8-bit field while VCI is a 16-bit field in the ATM cell header. A VPI identifies a link formed by a virtual path and a VCI identifies a channel within a virtual path. In this way,
Chapter 7: Glossary 97the cells belonging to the same connection can be distinguished. A unique and separate VPI/VCI identifier is assigned in advance to indicate which type of cell is following, unassigned cells, physical layer OAM cells, metasignaling channel or a generic broadcast signaling channel. Your ISP should supply you with the values.
