[Playstation 3] NAT Type

Hi all !

I've got a problem and i hope someone out there has a solution for me.
I'm playing COD:MW2 on my Ps3. The problem is, i can't connect to my friends (e.g. Party invitations) because i have a STRICT NAT Type.
I've tried alot (opened Ps3 and COD:MW2 Ports, enabled UnPn) but it didn't help. Only one thing has been changed since i opened the Ports: If i test my Network connection with the Ps3 itself (Not in a game) it says NAT-2, but COD:MW2 still brings up "NAT: Strict", which is NAT-3 :(

Would be awesome if someone could help me :3

I think this could help you...

Open the Ports 3074 for UDP and TCP.
Enable UPnP in the router and in your PS3.
Set an static IP for your PS3 in the routermenu.

What the ..
