6-8 WAN Setup
Figure 6-4 Traffic Redirect WAN Setup
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 Contivity 251 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 a LAN to LAN/Contivity 251 firewall rule that forwards packets from
the protected LAN (Subnet 1) to the backup gateway (Subnet 2).
