WAN Screens 

6.8 Traffic 

Redirect 

Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect to the Internet 
through its normal gateway. Connect the backup gateway on the WAN so that the Prestige still provides 
firewall protection.  
 

 

 

Figure 6-7 Traffic Redirect WAN Setup 

The following network topology allows you to avoid triangle route security issues (see the 

Appendices

) when 

the backup gateway is connected to the LAN. Use IP alias to configure the LAN into two or three logical 
networks with the Prestige itself as the gateway for each LAN network. Put the protected LAN in one subnet 
(Subnet 1 in the following figure) and the backup gateway in another subnet (Subnet 2). Configure a LAN to 
LAN/Prestige firewall rule that forwards packets from the protected LAN (Subnet 1) to the backup gateway 
(Subnet 2).
