Ok.. so I was able to get the IVP6 connectivity, & when I checked it on my Xbox, it said NAT unavailable, but when I would check detailed network settings, it said "your NAT appears to be open" bring up call of duty... syncing.. syncing.. unable to sync, try again or play offline... & then it was sayin some BS about a teredro IP or some crap.. (I don't remember the exact word, but I'm guessing you probably know what I'm talking about ... anyways.. I still wanna make it happen, but I have up for tonight.... gotta kill nhazis wit my boys in Okinawa
