Mine and friends NAT are both Open but still cant private chat?

Question

Hi all, about 2 days ago i was in a private chat with a friend and all of a sudden it froze so we restarted our Xbox 360's and once i accepted the chat invite it dissappeared. So I done a xbox live connection test to check my NAT, it was "Open" so I thought ok it isnt me, so I asked my friend to do a test aswell, and he said his said Open aswell, which puzzled me considering i've never heard of 2 people with Open NAT's not being able to private chat. So if someone could help me with this problem i would really appretiate it :). Thank you.

Answer 1

well NAT has nothing to do with it. i suggest you go to xbox site and look for port forwarding information cause its either one of your guys routers doesn't have all the correct ports open (linksys routers are fully supported by xbox live and you don't have to worry about this if you have one) or one of you just has a really poor connection
