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)
