Port Forwarding on Xfinity router

Support & Troubleshooting
1

Hi,

I recently moved from Verizon FIOS to Comcast Xfinity provider, and due to the router change I’m having trouble configuring port forwarding on the xfinity router. I’ve searched other posts and apparently Xfinity routers lack this feature. Is it really so ?? The router Xfinity provided me is a CISCO DPC3941T. I’m pasting below a screenshot of the port forwarding configuration screen… any advice ?? Am I really in trouble with this one ??

Weird it doesn’t look like you can forward a external port to a different internal port. Looks like the port forwarding is only direct mapping like port 80 to port 80.
