Solve a Messenger problem
Using a firewall to connect to .NET Messenger Service
Solve ID: 16

To connect to the .NET Messenger Service, you must open several ports. The following steps assume you're using the XP firewall service. Be aware: no hardware routers or non-Microsoft firewalls are currently compatible with UPnP (Universal Plug and Play). For this reason, for a non-UPnP firewall, you must open ports 5004-65535 in order to have voice/video conversations, and the rest of the ports listed in this article.
