When i go to the xbox live lobby i will create a private match pro face off 5 songs on expert. i then invite him but he just messages me saying it failed. So he makes a game invites me and i try join him and the message comes up saying failed to connect to player.
Is this because my NAT is closed? if so how do i tell when its open because ive tried opening it but he hasnt been on so i cant test to see if it is open?

Well, is it only on GH3? Can you play with your friends on any other games? Also, is there a possibility it's your friend and not you?

I think it's due to either your NAT or his NAT.

have you got UPnP on your router? You should look for stuff how to open NAT. (I don't know your router, so I can't give specific details.
