NAT / Virtual Server

Virtual Server allows you to direct incoming traffic from WAN side (identified by Protocol

Internal port is required only if the external port needs to be converted to a different port

number used by the server on the LAN side. A maximum 32 entries can be configured.

NAT / DMZ Host

The DMZ feature allows one network computer to be exposed to the Internet for use of a

special-purpose service such as Internet gaming or video conferencing. DMZ hosting

forwards all the ports at the same time to one PC. The Port Range Forwarding feature is

more secure because it only opens the ports you want to have opened, while DMZ

hosting opens all the ports of one computer, exposing the computer to the Internet.

Enter the

computer's IP address

and click

Apply/Save

to activate the DMZ host.
