Sticky: How to open your NAT in MW2

For some reason IW decided to close my NAT and I couldn't figure out how to get it open again, lol. I found a few vids on youtube but only one worked for me. This is designed for a Linksys router but may also work on others. Really easy stuff.

Hope it works for you too if you need it.
