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
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)
