Hi guys, just thought I might share something I found out just today. I often had disconnections (and a lot of other users too..) After testing my connection, the xbox said I had a limited NAT connection. That is because I use a router (which has I firewall..But that's another problem) To correct that, I had to configure the router so it forwards the following ports: Port 88 (UDP) Port 3074 (UDP and TCP) Port 53 (UDP and TCP) Port 80 (TCP) If you google "xbox ports forwarding" + the brand of your router, you'll easily find out how to do that.
