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 R&D department, service, sales department,

procurement department, 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) ÅÆ 168.85.88.253(WAN)

2. Service department subnet： 192.168.2.1/24(LAN) ÅÆ

168.85.88.252(WAN)

3. Sales department subnet： 192.168.3.1/24(LAN) ÅÆ

168.85.88.251(WAN)

4. Procurement department subnet

192.168.4.1/24(LAN) ÅÆ 168.85.88.250(WAN)

5. Accounting department subnet

192.168.5.1/24(LAN) ÅÆ 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

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)
