after this you get nat type 1 or 2( if you use Router, your nat type is 2)
While you should do this it will not actually make any difference in the fight against lag. The disadvantage of having a closed NAT is that you will only play against others with a closed NAT (unless ina party and you will be at a distinct disadvantage.) About 80% on most modern routers will have UpNp on as default, this basically means that the ports will be automatically opened for you and when you finish the game they will be closed. A few ISP's for some reason supply routers with UpNp off make sure it's on.

Correct, doing this during game will cause lag. Any attempt to fool MW3 matchmacking needs to be done during the lobby and also at the correct time.
