Figure 45 Traffic Redirect Example
The following network topology allows you to avoid triangle route security issues 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 filters that allow packets from the protected LAN
(Subnet 1) to the backup gateway (Subnet 2).
