Setting up Video and Voice over a router/non-XP firewall or NAT
Solve ID: 17
Summary:
If you are using a hardware router or non-xp internet sharing service you will not be able to use Video and Voice in Messenger. Messenger uses a technology called Universal Plug and Play (UPnP). Currently the only internet sharing (NAT) software that is UPnP compatible is the built in Internet Sharing included with Windows XP. Hardware and software vendors are building UPnP support into their products and should be available soon. For firewalls, the built-in Windows XP Internet Connection Firewall opens the ports for video/voice automatically, but other firewalls do allow video/voice to pass -- by opening ports 5004-65535 UDP.
