Prestige 324 Intelligent Broadband Sharing Gateway

Figure 9-7 Traffic Redirect WAN Setup

The following network topology allows you to avoid triangle route security holes when the backup gateway is connected to the LAN. Use IP alias to configure the LAN into two or three logical networks with the Prestige 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/Prestige firewall rule that forwards packets from the protected LAN (Subnet 1) to the backup gateway (Subnet 2).
