Port forwarding problems

"I have an Ubuntu 24.04 server connected by Ethernet. It appears in my connected devices as thedumpsterfire-79, with IPv4 address [Edited: "Personal Information"] and MAC [Edited: "Personal Information"]. It uses DHCP. However, it does not appear in the device selection list under WiFi → Advanced Settings → Port Forwarding. I need to forward ports to this server. Please refresh or repair the port-forwarding device inventory on my gateway."

@user_3e58yv Our team is here to help. I have the steps on how to set up port forwarding https://www.xfinity.com/support/articles/xfi-port-forwarding  

Before we get started with troubleshooting I have a link to share that has a list of the blocks ports on our network. Could you check to confirm if the ports you want are on this list.  https://www.xfinity.com/support/articles/list-of-blocked-ports
