Why won't my headphones and microphone work on Xbox Live?
Everytime I connect wirelessly to Xbox Live, I get a message saying my NAT is strict etc and that I won't be able to communicate with others on Xbox Live using the headphones and microphone. I was advised to enable UPnP (Universal Power and Play) but how do I do that? I use a Belkin ADSL Modem with Wireless G Router if that helps. ohlordi - 8 years ago
You need to open your ports, see here for more information: www.portforward.com/.
UPnP should be enabled by default. itwizz (Expert) - 8 years ago
