5.7  Traffic Redirect  
Traffic redirect forwards traffic to a backup gateway when the P-660HWP-Dx cannot connect 
to the Internet. An example is shown in the figure below.
Figure 50   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 P-660HWP-Dx 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).
