The UPnP (Universal Plug and Play) protocol is supported to bring to network connected
devices the ease of installation and configuration which is already available for directly
connected PC peripherals with the existing Windows 'Plug and Play' system. For NAT
routers, the major feature of UPnP on the router is "NAT Traversal". This enables
applications inside the firewall to automatically open the ports that they need to pass through
a router. It is more reliable than requiring a router to work out by itself which ports need to
be opened. Further, the user does not have to manually set up port mappings or a DMZ.
UPnP is available on Windows XP and the router provide the associated support for MSN
Messenger to allow full use of the voice, video and messaging features.
