How Do I Configure the Cable Modem 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.

If you are not familiar with the advanced settings detailed in this section, contact your cable service provider before you attempt to change any of the cable modem 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.
