Port Forwarding Not Working
Hello. I attempted to open a port on my router for one of my devices. It looks perfect in the Xfinity app. It shows the correct port number for the correct device, and with TCP/UDP.
However when I check to see if the port is actually open using an external site such as portchecker.io, it shows the port is closed.
Any ideas? It’s as if the router is simply ignoring the port forwarding I have put in place.
Edit: The port number is not a common one that Xfinity blocks (like 25).
Edit 2: It looks like many people have had this exact issue over the past couple of years. Is it an equipment issue? The only solution seems to be to buy a different router.
Edit 3: I even disabled IPv6 on the computer and created a DMZ for the computer’s IP address. The port STILL shows closed!
