6.10 Traffic Redirect
Traffic redirect forwards WAN traffic to a backup gateway when the ZyXEL Device cannot
connect to the Internet through its normal gateway. Connect the backup gateway on the WAN
so that the ZyXEL Device still provides firewall protection for the LAN.
Figure 76 Traffic Redirect WAN Setup
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 ZyXEL Device 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/ZyXEL Device firewall rule that
forwards packets from the protected LAN (Subnet 1) to the backup gateway (Subnet 2).
