MW2 NAT is Strict, change it to Open?

[gtr-2]

My computer is on wifi, the other computer is wired to the router. The router is on Passthrough because Static NAT shuts off the wired computer's connection. In MW2 it says my NAT is Strict, even though my firewall and the router have been forwarded. I even forwarded for Steam. Not sure what else to do to get an Open status. Any ideas?

You could always set your computer to the DMZ assuming you setup a static IP for your computer if port-forwarding doesn't work. Not sure if that can be done on wireless though.

I tried turning off the routers' firewall, this gives me a better connection. My status is still Strict but I am getting 4 bars now.

Ok, after portforwarding my router, then forwarding my anti-virus firewall, it was still resrticted. I turned off the anti-virus firewall and my status is now open and my connections are much better. I would usually get 120ms connections in the lobby, now I get around 80-100ms.
