Okay Multiplayer is working but I am having a problem I want to host a server for a game i made for my cod4 clan but I can't use vista, fyi its fpscreator not x. It works on the computer that the internal ip is .100 but when i try to start it on my other pc which is running Windows XP Professional it says on the bottom of the your ip thing in the game to connect to this session enter the ip 192.168.1.101.... I know how to do that but I connect to it it connects and all but all of the sudden it loses connection! the number of seconds go well over the limit i look at the server in remote desktop it shows ended game..... Ideas??? I forwarded the ports and all doe sit have to be on the internal ip 192.168.1.100?
