NAT Mode:
It allows Internal Network to set multiple subnet address and connect with the Internet through
different WAN IP Addresses. For example:The lease line of a company applies several real IP
Addresses 168.85.88.0/24, and the company is divided into Service, Sales, Procurement, and
Accounting department, the company can distinguish each department by different subnet for the
purpose of managing conveniently. The settings are as the following:
1. R&D department subnet:192.168.1.1/24 (LAN)
168.85.88.253 (WAN)
2. Service department subnet:192.168.2.1/24 (LAN)
168.85.88.252 (WAN)
3. Sales department subnet:192.168.3.1/24 (LAN)
168.85.88.251 (WAN)
4. Procurement department subnet:192.168.4.1/24 (LAN)
168.85.88.250 (WAN)
5. Accounting department subnet:192.168.5.1/24 (LAN)
168.85.88.249 (WAN)
The first department (R&D department) had set while setting interface IP; the other four ones have to be
added in Multiple Subnet. After completing the settings, each department uses the different WAN IP
Address to connect to the Internet. The settings of each department are as following:
Service
Sales
Procurement
Accounting
IP Address
192.168.2.2~254 192.168.3.2~254 192.168.4.2~254 192.168.5.2~254
Subnet Netmask 255.255.255.0
255.255.255.0 255.255.255.0 255.255.255.0
Gateway 192.168.2.1
192.168.3.1 192.168.4.1 192.168.5.1
Routing Mode:
It is the same as NAT mode approximately but does not have to correspond to the real WAN IP
address, which let internal PC to access to Internet by its own IP. (External user also can use the
IP to connect with the Internet)
