5.1.1.11.2 Example for Configuring EasyIP NAT Rule
(1) Requirements
In this example, an Internet cafe has a single Internet connection, and obtains eight
public IP addresses (from 218.1.21.0/29 to 218.1.21.7/29) from the ISP. Therein,
218.1.21.1/29 is used as the Internet connection
’s gateway IP address, 218.1.21.2/29
is used as the Device
’s WAN1 interface’s IP address. Note that 218.1.21.0/29 and
218.1.21.7/29 cannot be used as they are the subnet number and broadcast address
respectively.
The administrator want the hosts in the online game area (its address range is from
192.168.16.10/24 to 192.168.16.100/24) to use 218.1.21.3/29 to access the Internet.
To achieve this purpose, he should create an
EasyIP
NAT rule for them. The rule
’s
External IP Address
is 218.1.21.3,
Start Internal IP
is 192.168.16.10,
End Internal
IP
is 192.168.16.100, and
Bind to
is WAN1.
