Prestige 2602H-6xC Support Notes
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
1. Enable UPnP function in ZyXEL device
Go to Advanced->UPnP, check two boxes, Enable UPnP service and Allow users to make configuration
changes through UPnP.
The first check box enables UPnP function in this device.
The second check box allow users' application to change configuration in this device. For instance, if you
enable this item, then user's MSN application can assign dynamic port mapping to the router. So that network
administrator don't need to setup SUA port mapping in the router.
