I know there is a sticky that is posted to explain how to host...Well neither of those options worked for me... I went on youtube and followed the video instructions and i still cannot host custom games...I was wondering if anyone would give any tips/instructions on what you did to be able to host......

Turn your anti-vir firewall off, or open those ports aswell as @your modem

i would also liek to know. Hey kyny91 where do i go to turn my firewall off and on? because right when im done hosting games im going to want to turn the firewalll back on.

start menu -> settings -> control panel -> windows firewall ( or windows security) either one

this is for XP not sure about vista but i think it might be about the same
