How to connect to personal Nakama server non-locally

I don’t know if this is a question I should be asking in this forum but I assume there’re people here know how to do it.

I have tried using port forwarding before and it worked just fine but after I tried again this time for some reason my port doesn’t appear open, disabling the firewall made it appear open again but I don’t want to leave my firewall disabled on my personal machine and it should work regardless because it worked before without any issues.

Does anybody know how I can fix this problem or is there a better solution.
