Can't host on Madden 2005 please help.

Hello,

I have Madden 2005 for my PC. I am on a dell dimension 8200 with windows xp. I have the Service Pack 2 installed as well. I recently got Verizon dsl.

After I installed the new service pack, Madden 2005 wouldn't let me host a game. I then minimized the game and saw a popup asking me if I wanted to continue blocking Madden. I clicked no and then everything worked fine and I could host. Later though, after configuring our dsl service to send out our username and password through the router instead of through the computer itself, I could not host. There are no pop ups saying that the Service Pack Firewall is blocking madden, and in the exceptions list, the Main app for madden appears. I even turned the new firewall completely off and I still could not host a game. However I can join someone elses game with no problem. I looked at my router by typing in its IP address in the address bar, and it is allowing all traffic, so I have no idea what to do about this.

If anyone has any ideas I would really appreciate it,

Thank you
