Ok so my cousin has my MW2 and i have been trying to get my NAT open for the last hour and have finally found the best solution for the problem and it will only take 2 mins to do and you will have a open NAT type.
OK so first watch this youtube video
If you can't see the video properly thats ok go to this link http://forums.whirlpool.net.au/forum-replies.cfm?t=1739702 everything you need is there.
If you have Windows xp it should run normally same with vista.
If you are having trouble with the run command which will not open Telnet on Windows 7 then you need to do this:
- Go to start control panel
- Go to programs
- Where it says Program and Features underneath it click the button that says Turn Windows Features ON or OFF
-Scroll down and find Telnet Client and click the box next to it and hit ok.
After this it should let you run the telnet run command and then just follow the steps once done reset router and woooooooolllllllllllahhhhhhhhhhhh OPEN NAT type every time.
If you have any troubles PM me.
