Any one know how to change nat type in MW2

I'm not sure on what to do but I read you have to enable upnp...

It all has to do with port forwarding, the NAT type stays the same throughout all the games.

If there is a firewall or a router between the Xbox console and the networking hardware, and if the Xbox LIVE test reports an NAT problem, you may have to make configuration changes to enable communication on the specific network ports that are required by Xbox LIVE. This reconfiguration is known as "port forwarding." If you use an Xbox LIVE-compatible device or a Windows Vista-compatible device that has the correct firmware installed, you should not have to make these changes.

For more information about how to determine whether your networking hardware is compatible with Xbox LIVE, click the following article number to view the article in the Microsoft Knowledge Base:
944293 How to find out if your networking hardware is compatible with the Xbox LIVE Service
If your device is not on the compatible list, and if you experience the symptoms that are described in the "Introduction" section, you can try to open the following ports:

• TCP 80
• UDP 88
• UDP 3074
• TCP 3074
• UDP 53
• TCP 53

Oh I actually play on pc but I think you have to enable upnp, but I'm not sure how

Do you know what your router model is?

I have a linksys WRT54G2

I'm pretty sure your model does not support UPNP, so basically you're going to have to do forward your ports manually. There is a cool site out there that will give you a step-by-step guide on how to do it for both your router and Modern Warfare 2, so you don't need to worry about a thing.

Just click this link and follow all the instructions and you should have your NAT type set to "open" in no time.
