Alright I haven't had any problems connecting to Live or joining parties since I moved into my college dorm last year where the NAT is set a moderate for everyone.. my friends(that dont live here) are networking geniuses and always have their NATs open and they always host games and such
this past weekend though I haven't been able to join a single person on my friends list or play any kind of matchmaking in Halo, Cod, anything. I've talked to the IT people here at my college and they assured me nothing has changed and my friends swear up and down that their connections are still fine but I can't join anyone. It doesn't make sense because they keep saying that moderate can join moderate and open, and even strict can join open
I have a secure router in my room that has all the necessary ports forwarded, but only UDP 3074 is really forwarded according to the UPnP portmap.. I don't know what else to do so hopefully someone has some advice??
