GOW Multiplayer problem

[andy@moFo]

had a quick search but couldnt find this problem.. Im in need of some help!

tried to host a private game over xbox live and have been doing it everynight with my friend for about 2 weeks now, ive gone on tonight and its come up with the following message;

"You cannot host a multi-player game because of your firewall settings. Verify your firewalls security settings."

Now ive been through all my connections settings (PC + Xbox 360 Live) and everything is working normally and i dont current have any Firewall on my pc,

Can someone please explain how to correct this?

thanks in advance.

Personally I think that Xbox live is sentient and likes to play with peoples minds.

ill go along with that, i was playing an online game yesterday no problem, but when i go to host a private game it really doesnt like it.
