hey, ive never had a problem connecting in to network games or hosting network games. except for this one time, i am currently unable to host a game with my brother but it connects to his computer why is this? any suggestions? ive got the IP correct and no fire walls are up

try using hamachi, i had this problem and a freind suggested hamachi.

hope that helps

Make sure that he ticked the option for the game to be a Network Game as well.
