I have had trouble with CAll of Duty United Offensve and connecting to a server. I have Call of Duty original and that connects fine to severs, i have no firewall except windows which i have stopped running. I spoke to activision and they said to open the port on my Belkin router, but i don't know how to do that, i need to open port 28960 which is used for United Offensive. PLEASE HELP!!!
