If you want the dial-backup route to take first priority over the traffic-redirect route or even the normal 
route, all you need to do is set the dial-backup route’s metric to "1" and the others to "2" (or greater). 

of the routes mentioned above (see the IP Policy Routing chapter). 

The Prestige supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft standard 
(RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, 
wireless, etc.) connection. The PPPoE option is for a dial-up connection using PPPoE. 

 
For the service provider, PPPoE offers an access and authentication method that works with existing access 
control systems (for example Radius). PPPoE provides a login and authentication method that the existing 
Microsoft Dial-Up Networking software can activate, and therefore requires no new learning or procedures 
for Windows users. 
 
One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function 
known as dynamic service selection. This enables the service provider to easily create and offer new IP 
services for individuals. 
 
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific 
configuration of the broadband modem at the customer site. 
 
By implementing PPPoE directly on the Prestige (rather than individual computers), the computers on the 
LAN do not need PPPoE software installed, since the Prestige does that part of the task. Furthermore, with 
NAT, all of the LANs’ computers will have access.
