"Re: nat 3 to nat 2

I tried all the router suggestions and still got nat 3. after much 
frustration I called my ISP. Do this. Ask if your IP address is private 
or public. My ISP sets u up as private. I had them change it to 
public...BINGO Nat 2. Hope this helps."

If you read above, it appears that his ISP ran NAT444 normally, which 
the PS3 categorizes as nat 3, which means he can't reach COD. Dude, 
customers MUST reach COD. :)
