Hi Everyone,

I decided to setup a dedicated server yesterday but I'm having the issue where I can't communicate with the server over the internet. I can communicate with it over LAN but if I try my direct WAN ip or even allow it to be public, it does not work. I have verified that my port is open on my router both with port scans and with Wireshark on both my client and server which shows that I am sending packets and the server is receiving them but the game server is not seeing it. The server is Ubuntu 20.04 with UFW enabled (Rules are present) and the client is macOS 12.4. I have also tried a Windows 10 client but the same result occurs. I turned on verbose logging and the only https://pastebin.com/hFmE6JTU is what came up.

[Edit] Another thing of note is I am using AMP by CubeCoders to manage the game instance. I thought I should mention it but I don't think its causing issues as like I said, the server is accessible over LAN its just WAN operation.

If anyone could help that would be great. Thanks

Alright, I finally figured it out. For anyone that is using AMP to host the server and you have multiple NICs on the system specify one of them. In my case one of them faces a DMZ-like network which is most directly facing to the internet while the other is connected to my lab network and for some reason it was choosing the lab NIC even though the data was coming in on the DMZ NIC.
