Note
：
1.
Make sure your WAN IP address (Internet IP address) is a public IP address.
Private IP addresses are not routed on the Internet.
2.
Make sure you enter the correct service port numbers.
3.
To ensure that your server computer always has the same IP address,
assign a static IP address to your PC.
4.
Operating System built-in firewall and some anti-virus programs may block
other PCs from accessing resources on your PC. So it is advisable to disable
them before using this feature.
5.
When finished, click
Save
to save your settings.
For example: if your WAN IP address is 202.33.56.88, when accessing your FTP
server from external network, your friends only need to enter
ftp://202.33.56.88:21 in their browsers.

DMZ Settings
The DMZ function is to allow one computer in LAN to be exposed to the Internet for a
special-purpose service as Internet gaming or video conferencing.
DMZ Host IP:
The IP address of the computer you want to expose.
Note:
DMZ hosting forwards all the ports at the same time to one PC, different from
Port Range that can only open special port you point to.
DMZ host poses a security risk. A computer configured as the DMZ host loses
much of the protection of the firewall and becomes vulnerable to attacks
