Scenario:
You have set up an FTP server within your LAN.
Goal:
Open the FTP server to internet users and enable family members who are not at home to
access the resources of the FTP server from the internet.
Solution:
You can configure the DMZ host function to reach the goal.
Assume that the information of the FTP server includes:
-
IP address: 192.168.0.125
-
MAC address: 00:00:00:00:00:01
-
Service port: 21

The WAN IP address of the router: X.X.X.X.
Please ensure that the router obtains an IP address from the public network. This function may not
work on a host with an IP address of a private network or an intranet IP address assigned by ISPs
that start with 100. Common IPv4 addresses are classified into class A, class B and class C. Private
IP addresses of class A range from 10.0.0.0 to 10.255.255.255; Private IP addresses of class B range
from 172.16.0.0-172.31.255.255; Private IP addresses of class C range from 192.168.0.0-
