8.8.3. UPnP
By using the Universal Plug and Play (UPnP) protocol, a host in the LAN can ask the router to perform
specific port conversion, to enable an external host to access resources on the internal host when
necessary. For example, if MSN Messenger is installed on Windows ME and Windows XP operating
systems, UPnP can be used for audio and video conversations. In this way, functions restricted by NAT
can work properly.
Choose
Network Application > UPnP and the UPnP page is displayed.
