P320W Support Notes
In t his example, we will introduce how to e nable 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, su ppose 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.
