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).
