Xbox live NAT is moderate, how do i change it?

When i play halo 3 in matchmaking a message comes up saying my NAT is not open. I went and tested the connection and it says my NAT is set to moderate. I have a router. How do i change the NAT to open? Sometimes the NAT will say its open and other times it says its moderate.








Another problem I'm having with my xbox is when i go into the dashboard it freezes and i have to turn off my console. Anyone know how to fix this?

The same happens to me! Maybe this his happening now because of Live an not us. It is all happening to us at random. The freezing thing happens.... You could try and buy a fan for the 360. I have a madcatz fan and I played 9 hours straight and it worked great. Try not to press the 360 button when you are loading something.
Reply:i have the exact same problem! Like every single thing that you said happened to you is happening to me. Hope we both find the answers!
Reply:the NAT problem happens to me too, when i got into matchmaking it will say not open, then i will play it then next time i play it will be open type NAT, im not sure about the other problem though, could be playing for a long time/ over heating
