server's 1-1 NAT mapping public IP address- 192.168.35.100.

2. From the Virtual Server setting, ZyWALL USG forwards it to the internal IP

192.168.105.37.

3. The Web server receives a request from the same subnet and replies it directly to

PC through L2 switch dispatching. This is known as "triangle route".

Please follow these steps to configure the ZyWALL USG in order to solve the triangle

route problem:

1-1 NAT mapping Configuration:

Firstly create two address object: WEB_WAN as 192.168.35.100 and WEB_LAN as

192.168.105.37. After that, create the Virtual Server rule of incoming DNAT

translation to allow the server connect to outside network.

Create one Policy Route rule for outgoing SNAT to translate the private IP to public

one.

After these two steps, the 1-1 NAT mapping on ZyWALL USG is complete.
