ZyWALL 2WG User’s Guide

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).
