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 a LAN to
LAN/Prestige firewall rule that forwards packets from the protected LAN (Subnet 1) to the backup gateway
(Subnet 2).
