How Do I Configure My DOCSIS Residential Gateway?

Configuring Port Forwarding for Local IP Addresses

Use the Setup Advanced Settings - Port Forwarding page to configure port forwarding for local IP addresses. Port forwarding allows you to run a server on the LAN by specifying the mapping of TCP/UDP ports to a local PC. You must also set up a fixed private LAN IP address for the destination device.

Note: If you are not familiar with the advanced settings detailed in this section, contact your service provider before you attempt to change any of the residential gateway default advanced port forwarding settings.

Click Port Forwarding in the Advanced Settings section of the Setup page to access the Setup Advanced Settings - Port Forwarding page.

The following example illustrates how to use the port forwarding feature to configure the Microsoft X-Box Online Live for Internet gaming.

Note: For most widely used applications (including Microsoft X-Box Online Live), the built-in firewall automatically maps and opens ports required for that application while the application is in use.

1Set the device to be used for port forward to a fixed IP address, for example, 192.168.0.5.

2In the first entry of the Port Forwarding area of the page, enter the same IP address (192.168.0.5) in the Local IP Address field.
