Traffic Redirect - ZyXEL Communications P-2612HW-F1 User Manual

6.6 Traffic Redirect

Traffic redirect forwards traffic to a backup gateway when the ZyXEL Device
cannot connect to the Internet. An example is shown in the figure below.
Figure 68 Traffic Redirect Example
LAN
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 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
filters that allow packets from the protected LAN (Subnet 1) to the backup
gateway (Subnet 2).
