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. See the next section for information on DHCP setup.

To access the LAN Settings menu, click the LAN button in the Home directory.

Configure LAN IP settings

To change the LAN IP Address or LAN Network Mask, type in the desired values and click the Apply button. Your web browser should automatically be redirected to the new IP address.

DHCP Server Settings for the LAN

The DHCP server is enabled by default for the Router’s Ethernet LAN interface. DHCP service will supply IP settings to computers 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, you must change the range of IP addresses in the pool used for DHCP on the LAN.

To display the DHCP Server menu, click the DHCP button in the Home directory. Active DHCP Clients appear listed in the DHCP Client List below the configuration menu. Information about DHCP clients includes the IP address, MAC address, host name and lease time are displayed in the list.

Configure DHCP server settings for the LAN

The three options for DHCP service are as follows:

• You may use the Router as a DHCP server for your LAN.
• You can disable DHCP service and manually configure IP settings for workstations.
• You use DHCP service provided by your ISP.

Follow the instructions below according to which of the above DHCP options you want to use.

To use the built-in DHCP server, click to select the DHCP Server option if it is 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. The Ending IP Address is the highest IP address number in the pool. 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.

Disable the DHCP Server

To disable DHCP, click to select the No DHCP option and click on the Apply button.

DHCP Relay

To use DHCP service from your ISP, select the DHCP Relay option and type the DHCP Relay IP address in the space provided. Click Apply to begin DHCP relay from the ISP.

DNS Server Settings

The Router can be configured to relay DNS from your ISP or another available service to workstations on your LAN. When using DNS relay, the Router will accept DNS requests from hosts on the LAN and forward them to the ISP (or alternative) DNS servers. DNS relay can use auto discovery or the DNS IP address can be manually entered by the user. Alternatively, you may also disable the DNS relay and configure hosts on your LAN to use DNS servers directly. Most users who are using the Router for DHCP service on the LAN and are using DNS servers on the ISP's network. Leave DNS relay enabled (either auto discovery of user configured), unless specified by your ISP.

Configure DNS Settings

In the DNS Relay Selection pull-down menu, choose to Use Auto Discovery, Use User Configured or Disable DNS relay.

If you have not been given specific DNS server IP addresses or if the Router is not pre-configured with DNS server information, select the Auto Discover option for DNS relay. Auto discovery DNS instructs the Router to automatically obtain the DNS IP address from the ISP through DHCP. If your WAN connection uses a Static IP address, auto discovery for DNS cannot be used.

If you have DNS IP addresses provided by your ISP, enter these IP addresses in the available entry fields for the Preferred DNS Server and the Alternative DNS Server.

If you choose to disable DNS relay, it will be necessary to configure DNS settings for hosts on the LAN since they will not be depending on the Router to forward the DNS requests.

When you have configured the DNS settings as desired, click the Apply button.

Advanced Router Management

This chapter introduces and describes the management features that have not been presented in the previous chapter. These include the more advanced features used for network management and security as well as administrative tools to manage the Router, view statistics and other information used to examine performance and for troubleshooting.

Use your mouse to click the directory tabs and menu buttons in order to display the various configuration and read-only menus discussed below. The table below summarizes again the directories and menus available in the management web interface. In this chapter you will find descriptions for the menus located in the Advanced, Tools and Status directories.

Port Forwarding

Use the Port Forwarding menu to create Virtual Server functions through the Router. A Virtual Server can allow remote users to access services on your LAN such as FTP for file transfers or SMTP and POP3 for e-mail. The DSL-G604T will accept remote requests for these services at your Global IP Address, using the specified TCP or UDP protocol and port number, and then redirect these requests to the server on your LAN with the Private IP address you specify. Remember that the Private IP Address must be within the range specified for your LAN.

The Virtual Server feature employs UDP/TCP port redirection to direct traffic through the WAN port to specified servers on your private network. Port redirection can also be used to direct potentially hazardous packets to a proxy server outside your firewall. For example, you can configure the Router to direct HTTP packets to a designated HTTP server in the DMZ. You can define a set of instructions for a specific incoming port or for a range of incoming ports. Each instruction set or rule is indexed and can be modified or deleted later as needed.

Virtual server configuration sets can be used together with complimentary features such as Firewall Rules, DMZ devices and IP Filters to improve efficiency and security. Consider how these other functions will effect the virtual server sets you have configured and enabled.

The table below describes the configuration settings presented in the Virtual Server menu.

Figure 4- 1. Virtual Server Menu and List

To modify virtual server settings for any previously created virtual server set listed, click on the note pad icon in the right hand column of the Virtual Servers List for the set you want to configure. The set will appear highlighted in the list and the parameters that have been configured appear in the settings fields above the list. Adjust the settings as desired and click the Apply button to put them into effect.

To configure a virtual server set, define the following settings in the Virtual Server configuration menu located in the top half of the browser window.

Click the Apply button to put the new virtual server configuration set or modification into effect. Any server sets configured in the menu will appear in the Virtual Server List with the new settings. The Router must save the new settings and reboot before the new virtual server configurations are applied.

To remove any configuration set from the Virtual Server List, click on the trashcan icon for set you want to delete.

Note Some applications require multiple TCP or UDP ports to function properly. Applications such as Internet gaming, video conferencing, and Internet telephony are some examples of applications that often require multiple connections. These applications often conflict with NAT, and therefore require special handling. See the discussion of DMZ configuration below.

Filter rules in the Router are put in place to allow or block specified traffic. The Filter Rules however can be used in a single direction to examine and then Allow or Deny traffic for Inbound (WAN to LAN) or Outbound (LAN to WAN) routed data. The rules based on IP address and TCP/UDP port.

Configure the filter rules as desired and click the Apply button to create the rule. The newly created rule appears listed in the Outbound Filter List at the bottom of the menu. The table below describes the various parameters that are configured for the filter rules.

Figure 4- 2. Filters Configuration Menu

To modify any previously created filter rule, click on the note pad icon in the right hand column of the Filter List for the set you want to configure. Adjust the settings as desired and click the Apply button to put the new settings into effect.

First determine the direction of the traffic you want the rule to filter. To filter WAN to LAN traffic, select the Inbound Filter option. Any new Inbound Filter rules created will appear in the list. Likewise, should you to filter LAN to WAN traffic, create an Outbound Filter rule.

The parameters described below are used to set up filter rules.

Click the Apply button to put the new rule into effect. Any filter rule configured in the menu will appear in the Filters List with the new settings. The Router must save the new settings and reboot before the new rules are applied.

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.

Figure 4- 3. DMZ IP address configuration

To designate a DMZ IP address, type in the IP Address of the server or device on your LAN, select the Enabled radio button and click the Apply button. To remove DMZ status from the designated IP address, select the Disabled radio button and click Apply. It will be necessary to save the settings and reboot the Router before the DMZ is activated.
