NAT mode
Multiple Subnet allows local port to set multiple subnet works and connect with the internet through different
WAN 1 IP Addresses.
For instance: The lease line of a company applies several real IP Addresses 168.85.88.0/24, and the
company is divided into R&D department, service, sales department, procurement department, accounting
department, the company can distinguish each department by different subnet works for the purpose of
convenient management. The settings are as the following:
1. R&D department sub-network: 192.168.1.11/24(LAN ) 168.85.88.253(WAN 1)
2. Service department sub-network: 192.168.2.11/24(LAN ) 168.85.88.252(WAN 1)
3. Sales department sub-network: 192.168.3.11/24(LAN ) 168.85.88.251(WAN 1)
4. Procurement department sub-network: 192.168.4.11/24(LAN ) 168.85.88.250(WAN 1)
5. Accounting department sub-network: 192.168.5.11/24(LAN ) 168.85.88.249(WAN 1)
The first department(R&D department) was set while setting interface IP, the other four ones have to be added

connect to the internet. The settings of LAN computers on service department are as the following
