Port Range Forwarding

The Port Forwarding screen sets up public services on your network, such as web servers, ftp servers, e-mail servers, or other specialized Internet applications. (Specialized Internet applications are any applications that use Internet access to perform functions such as videoconferencing or online gaming. Some Internet applications may not require any forwarding.) (See Figure 6-26.)

When users send this type of request to your network via the Internet, the Router will forward those requests to the appropriate PC. Any PC whose port is being forwarded must have its DHCP client function disabled and must have a new static IP address assigned to it because its IP address may change when using the DHCP function.

•Application. Enter the name you wish to give each application.

•Start and End. Enter the starting and ending numbers of the port you wish to forward.

•Protocol. Select the type of protocol you wish to use for each application: TCP, UDP, or Both.

•IP Address. Enter the IP Address and Click Enabled.

When finished making your changes on this tab, click the Save Settings button to save these changes, or click the Cancel Changes button to undo your changes.
