Great that you guys sorted out the MP issue yourselves
Can someone create one or two FAQ questions and answers in relation to this subject for the benefit of future users. I will put it in the latest readme and eventually the new version of the FPSC help. Here is what I have right now:
Multiplayer
-----------
QG01> Sometimes, when I build a multiplayer game, the IP is blank and I cannot host/join a multiplayer game?
AG01> Open up the SETUP.INI file associated with the game, and ensure the field reads MULTIPLAYERGAME=1
QG02> I have created my arena game but when I try to host a game, all my friends say they see waiting to join and stays there?
AG02> This is because your game server is being blocked. if you have a firewall, ensure it is not blocking the game executable, and that it has full permission for inbound and outbound communication. Another likely cause is that your router is blocking the game, hiding the game server from the internet. In this case you must configure your router using the Port Forwarding features of the device. Set the router to allow communication to your local IP address (usually 192.168.0.XXX) where XXX is the ID of the local machine, and specify port 2303 which is the UDP communication port for the game server. You can further determine port activity by using port forwarding detection tools to configure the port for you (such as http://www.soft32.com/download_123463.html).
