I was having a few issues with games and chat on the Xbox 360. The device should use uPnP for port forwarding but this was problematic for me. Firstly I needed to setup the games console with an IP address that would stay the same so I did this in the router’s settings so that DHCP always assigned the same IP to the MAC address of the console.
The next step was to setup the necessary port forwarding from the outside WAN to the inside LAN host (i.e. the console). The following ports needed to be forwarded:
- Port 88 (UDP)
- Port 3074 (UDP and TCP)
- Port 53 (UDP and TCP)
- Port 80 (TCP)
- Port 1863 (UDP and TCP) – for Video Kinect
