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.

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.
