Argh! NAT in MW2

Hello,
I have this problem with my mw2 disc or possibly my ps3, this is what happens every time I put in my mw2 disc and load it, the game logo comes up, but then the game screen goes blank and suddenly it goes back to my ps3 home menu. If I log out of PSN (play station network) and go into mw2 the game loads perfectly I can play campaign spec ops but if I go to multiplayer --->online then it says you need to sign in, when I do then the same problem occurs, blank screen and then it loads me back to the ps3 menu. I am becoming very frustrated with this problem and have searched the internet for solutions but nothing has been found. I need your help, If you know how to solve this probl...
