I see settings in server.ini for server port, and RCON IP and port, but no way to tell it which IP/interface to bind the main server to. Right now it listens on every IP on the system:
udp 0 0 0.0.0.0:27003 0.0.0.0:* 22589/./bin/Avorion
udp 0 0 0.0.0.0:27020 0.0.0.0:* 22589/./bin/Avorion
I need to limit it to a single IP
EDIT: poking through the AvorionServer binary, I discovered that there's a "--ip" command line option
