The “Triangle Route” Solutions

This section presents you two solutions to the “triangle route” problem.

IP Aliasing

IP alias allows you to partition your network into logical sections over the same Ethernet

interface. Your ZyWALL supports up to three logical LAN interfaces with the ZyWALL

being the gateway for each logical network. By putting your LAN and Gateway B in different

subnets, all returning network traffic must pass through the ZyWALL to your LAN. The

following steps describe such a scenario.

1 A computer on the LAN initiates a connection by sending a SYN packet to a receiving

server on the WAN.

2 The ZyWALL reroutes the packet to Gateway B, which is in the 192.168.2.1 to

192.168.2.24 subnet.

3 The reply from WAN goes through the ZyWALL to the computer on the LAN in the

192.168.1.1 to 192.168.1.24 subnet.
