It seems that I can't connect to certain people through private chat. I can connect to some but when others invite me (or i invite them) it just stays on Joining Chat for about 5 seconds and then goes off. My 360 is in the DMZ so is it a problem on their end or mine? and how do you solve it. Also, is there a way to give the 360 a static IP so i dont have to keep switching the DMZ about?
