Chapter 7 WAN Setup so the IP Address and Gateway IP Address fields are not applicable (N/A) as the DHCP server assigns them to the P-794H. 7.7 Traffic Redirect Traffic redirect forwards traffic to a backup gateway when the P-794H cannot connect to the Internet. An example is shown in the figure below. Figure 81 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-794H 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). Figure 82 Traffic Redirect LAN Setup 130 P-794H User's Guide

Traffic Redirect
Traffic redirect forwards traffic to a backup gateway when the P-794H cannot
connect to the Internet. An example is shown in the figure below.
Figure 81
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-794H 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).
