We’re developing a multiplayer game that supports both dedicated servers and listen servers. We use the Steam online subsystem.
The server ports can be specified with the built-in launch arguments -queryport=27015 -port=7777. While -port is passed onto Steam by the online subsystem, it is not a ‘real’ UDP port and in reality only -queryport is needed for the game server traffic.
There is no issue in connecting to the server. However, our dedicated server hosting partner would really prefer to be able to specify a separate game port and query port. Is this possible?
I have tried bAllowP2PPacketRelay=false in DefaultEngine.ini, but it does not affect this issue.
