Hey Guys, Having issues getting a friends XBOX working properly. We can get the XBOX connected to XBOX Live fine, and see online friends fine, as well as download Apps like Netflix and the like no problem. The main issue is we can't connect to any games or parties. The NAT is Open, the XBOX is connected with a CAT-5 cable to an E-1000 Linksys Router. I've cleared the system cache, disconnected and reconnected multiple times. Still no luck. Anyone have this problem before? Thanks for any input =)

Maybe open some ports? That's what I had to do.

I cant open any ports, I've tried to access the router but they cant remember any of the password for the router.

Dose your friend have xbox live subscribtion

Yes.
