so the IP Address and Gateway IP Address fields are not applicable (N/A) as

Traffic redirect forwards traffic to a backup gateway when the P-794H cannot

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).
