17. Configuring and Using WAN backup (For P660H & P660HW)

WAN Backup, also known as Traffic Redirect, is a routing mechanism to forward

WAN traffic to a backup gateway when the Prestige cannot connect to the Internet

through its normal gateway. Thus this sets the backup gateway as an auxiliary backup

of your WAN connection. Once the Prestige’s WAN connection is down, the Prestige

will try to forward outgoing traffic to the configured backup gateway.

This section shows you how to set up P660HW-61 to redirect WAN traffic to a

backup gateway (P2302R) on the LAN.

In the example network, the P660HW-61 will normally forward WAN traffic to the

Internet through the ADSL connection. When the ADSL connection is down, the

P660HW-61 will automatically redirect WAN traffic to the backup gateway by

rewriting its routing table. The following shows this backup routing setting for

P660HW-61 and P2302R.
