Problem with port forwarding not working on my CAX80 connected to Xfinity.
I was having the same problem with port forwarding not working on my CAX80 connected to Xfinity. After double and triple checking for errors on my part I checked the web for a solution and found your...
UPnP is disabled from the start. I am forwarding port 32400 to my Plex server. Xfinity does not block the port with FW 2.1.5.2.
For troubleshooting FW 5.1.1.8 I tried forwarding several ports, including port 80. I tested the ports from https://www.yougetsignal.com/tools/open-ports/. Every port was closed.
Loading FW 2.1.5.2 with identical settings port 32400 is open and I can direct connect to my Plex server and yougetsignal shows any port I forward as open.
The only thing that is different between PF working and not working is FW 2.1.5.2 vs FW 5.1.1.8

But it stops working after a while?
It stops working when Xfinity installs FW 5.1.1.8. It works continuously with no interruption as long as FW 2.1.5.2 is installed.

Got it. I found another report on that here (a year back).
Is the plex server being assigned an IP address within the DHCP pool range?
If not, you should try giving it a reserved address within the range.

DHCP is disabled on the CAX80. My Domain Controller runs DNS and DHCP. I assign static IPS to my servers. Everything on the LAN is on the same 192.168.0.0/24 subnet.
