DSL-504T DSL Router User’s Guide

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.

Parameter	Description
		Provide a name for the rule. This name will not appear in the list
Rule Name		below, however it may be useful if you later need to edit the
		settings for the rule. Rule names are optional.
		This is the IP address of the server on your LAN that will provide
		the service to remote users. The Private IP address is used to
Private IP		direct the service to a specific computer on your private network
		such as an FTP, Email or public web server. Type in the IP
		address of the server used for the service being configured here.
		You can select the transport protocol (TCP or UDP) that the
		application on the virtual server will use for its connections.
		Select one of the following options from the pull-down menu to
Protocol		define a TCP, UDP or Both. The choice of this protocol is
		dependent on the application that is providing the service. If you
		do not know which protocol to choose, check your application’s
		documentation.
		Configure a range of ports for forwarding. Type the lowest
		numbered port in the range in the Port Start space. Type the
		highest numbered port in the Port End space. For a single port,
Port Start /Port End		just enter the same number in both spaces.
		Virtual server port redirection must be used with a specified
		server or computer on the LAN (identified by the Private IP
		address).
		This is the local port being forwarded to from the Port Start/Port
		End port(s). Keep in mind that if you use a non-standard port
Port Map		number for an application with a reserved UDP/TCP port, some
		additional configuration may be required for the servers or
		workstations using the application on the LAN side.

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.

	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
Note
	NAT, and therefore require special handling. See the discussion of DMZ configuration below.
