My server is up and running but I don't see an effective setting for ports being used.. I can change the game server port in the settings but the others such as steam port cannot be changed. Sprry, not at the console now to view those variables specifically.
Once I get better control of which ports are used I'll open my firewall up to allow global connections to my server.
BTW, my server runs great so far. Would love to do some stress testing.
I've also begun development with the LGSM team to get LGSM support for Avorion to make it ultra easy to get a Linux server up and running.
