I don't know why but for quite sometime now I have been unable to host games. But I can still upload to people like in P2P programs such as Bittorrent and Shareazaa(Kinda like Kazaa but with no adware or spyware). My PC does have a firewall but it is disabled. Also my computer does run through a router for spillting the internet to various PC's and laptop's in the house. I have a high speed cable connection from Charter. Does anyone know what I might beable to do to fix this problem or if it is even possible for my comupter to host games?
