2. Using UPnP in ZyXEL devices
In this example, we will introduce how to enable UPnP function in ZyXEL devices. Currently, Microsoft MSN
is the most popular application exploiting UPnP, so we take Microsoft MSN application as an example in this
support note. You can learn how MSN benefit from NAT traversal feature in UPnP in this application note.
In the diagram, suppose PC1 and PC2 both sign in MSN server, and they would like to establish a video
conference. PC1 is behind PPPoE dial-up router which supports UPnP. Since the router supports UPnP, we
don't need to setup NAT mapping for PC1. As long as we enable UPnP function on the router, PC1 will assign
the mapping to the router dynamically. Note that since PC1 must support UPnP, we presume that it's OS is
Microsoft WinME or WinXP.
Device: Prestige Router
Service: NAT function provided by Prestige Router
Control Point: PC1
