Traffic Redirect
Traffic redirect forwards traffic to a backup gateway when the Prestige cannot connect to the Internet. An
example is shown in the figure below.
Figure 8-14 Traffic Redirect Example
The following network topology allows you to avoid triangle route security issues when the backup gateway is
connected to the LAN or DMZ. 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 filters that allow packets from
the protected LAN (Subnet 1) to the backup gateway (Subnet 2).
