My PS3's NAT setting for the new call of duty says strict and its so bad that i cant even knife people, i've tried turning off my firewall and opening ports and i cant seem to fix the problem does anyone know what i need to do to fix this?
Are you saying that you are experiencing bad lag during games? That doesn't have anything to do with NAT or firewall settings. Are you using the PS3 on a wired connection or wireless? If wireless check your wireless network to make sure you are getting a good signal or switch to wired setup. If you are already wired, I would check your Internet connection speed.
