hey im trying to play the need for speed underground demo online with my friend. he is able to play with people but when i try to it shows me the lobbies and i can send challenges to people but when it gets to the loading part it stops and says cannot connect, might be cuase by a firewall. I do not have any firewalls so i immediately thought it could be me router, so i unhooked my router and hookep up my cable modem directly to my pc and configured it to work like that (dynamic ip) and the game worked perfectly, then i hook back up the router and it doesnt work.
does anybody know what could be wrong? ive tried changing some settings in the router but nothing seems to help, i turned off the discard ping from lan side and that didnt help and it isnt set to block any ports or anything.
i have a dlink dl-704p router with latest firmware, connected to and external cable modem, and i have 2 computer (one xp and one 98, neither can play online) and my ps2 (the ps2 works online)
