Wireless-G ADSL Home Gateway
The Port Range Forwarding Tab
The Port Range 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.)
When users send this type of request to your network via the Internet, the Gateway will forward those requests to
the appropriate computer. Any computer whose port is being forwarded should have its DHCP client function
disabled and should have a new static IP address assigned to it because its IP address may change when using
the DHCP function.
• Application. Enter the name of the application in the field provided.
• Start and End. Enter the starting and ending numbers of the port range you wish to forward.
• Protocol. Select the protocol you wish to use for each application: TCP, UDP, or Both.
• IP Address. Enter the IP Address of the appropriate computer.
• Enable. Click the Enable checkbox to enable forwarding for the chosen application.

The Port Triggering Tab
Port Triggering is used for special applications that can request a port to be opened on demand. For this feature,
the Gateway will watch outgoing data for specific port numbers. The Gateway will remember the IP address of the
computer that sends a transmission requesting data, so that when the requested data returns through the
Gateway, the data is pulled back to the proper computer by way of IP address and port mapping rules.
• Application. Enter the name you wish to give each application.
• Triggered Range. Enter the starting and ending port numbers of the Triggered Range.
• Forwarded Range. Enter the starting and ending port numbers of the Forwarded Range.
• Enable. Click the Enable checkbox to enable port triggering for the chosen application.
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.
