Hello! thank you for setting up this docker. My main goal is to set up the server so that my friends outside the network could join. I was able to portforward ports 2456-2458 with the UDP protocol. When I run the container, I can connect via steam server list using LocalIP:PORT+1 and I can actually play in game. But My friends cannot find the server (either ingame or steam server list) Which seems to be an issue with the port forward. Is there something else I'm Missing?
