Ports

Preamble

This is only needed if you intend to host a server on your computer. This is not required for joining a game.

Copy and pasted Ports.txt from HX

ServerPort is set as Port option under [URL] inside HX.ini. This needs to be forwarded to allow other clients to join.

ServerQuery/ServerUplink will use up the two next available ports, so for masterserver/gamelisting to work these need to be forwarded too. This will typcially be 7790-7792 unless other programs use these ports up already. So you might need to increase the range upwards, say 7790-7800.

You can check HXServer.log for: DevNet: TcpNetDriver on port 7790 Init: UdpServerQuery Port 7791 successfully bound. Init: UdpServerUplink Port 7792 successfully bound.

If the last two differ, you need to forward these ports.

Just UDP is required for forwarding.
