Description
Redirect
Active
Select this check box to have the Prestige use traffic redirect if the normal WAN connection goes down.
If you activate traffic redirect, you must configure at least one Check WAN IP Address.
Metric
This field sets this route's priority among the routes the Prestige uses.
The metric represents the "cost of transmission". A router determines the best route for transmission by
choosing a path with the lowest "cost". RIP routing uses hop count as the measurement of cost, with a
minimum of "1" for directly connected networks. The number must be between "1" and "15"; a number
greater than "15" means the link is down. The smaller the number, the lower the "cost".
Backup
Gateway
Type the IP address of your backup gateway in dotted decimal notation. The Prestige automatically forwards
traffic to this IP address if the Prestige's Internet connection terminates.

Using Universal Plug n Play (UPnP)
1. What is UPnP
UPnP (Universal Plug and Play) makes connecting PCs of all form factors, intelligent appliances, and wireless
devices in the home, office, and everywhere in between easier and even automatic by leveraging TCP/IP and
Web technologies. UPnP can be supported on essentially any operating system and works with essentially any
type of physical networking media – wired or wireless.
UPnP also supports NAT Traversal which can automatically solve many NAT unfriendly problems. By UPnP,
applications assign the dynamic port mappings to Internet gateway and delete the mappings when the
connections are complete.
The key components in UPnP are devices, services, and control points.
