Figure 38 Traffic Redirect Example

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).
