Help!!!!!!!!!!!!!!!!!!!!!!

IM Desperate! im having problems with XBL Nat settings. I cant play halo 3 with a strict NAT and its all i play! I'm using a Motorola 2210-02 modem ONLY and have tried almost every site for answers. I had my NAT open for a time but i can't keep it open. PLEASE HELP!

 

If you can't leave it open, you may be out of luck. NAT messes up online gaming. I put my 360 in the DMZ, just because that was easiest to do. If that's not an option for you... you might be out of options.

 

So you're not using a router? The XBOX is wired directly up to the modem?

You might want to look into getting a router. That way you can open certain ports and open your NAT. That's what I had to do.

Here's a list of the ports the XBOX will use for LIVE service. I opened these up and now I game with an open NAT.
