IP alias 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 ZyWALL 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/ZyWALL firewall rule that forwards packets
from the protected LAN (Subnet 1) to the backup gateway (Subnet 2).
