8.3 Port Triggering
Port Triggering allows you to do port forwarding without setting a fixed PC. By setting Port Triggering rules,
you can allow inbound traffic to arrive at a specific LAN host, using ports different than those used for the
outbound traffic. This is called port triggering since the outbound traffic triggers to which ports inbound
traffic is directed.
Application: Enter the name of the application in the field provided.
Triggered Port Range: Enter the number of the first and the last port of the range, which should be
triggered. If a PC sends outbound traffic from those ports, incoming traffic on the Forwarded Range will
be forwarded to that PC.
Forwarded Port Range: Enter the number of the first and the last port of the range, which should be
forwarded from the Internet to the PC, which has triggered the Triggered Range.
Enable :Click the Enable check box to enable port triggering for the application.

DMZ
The DMZ (DeMilitarized Zone) hosting feature allows one local user to be exposed to the Internet for use
of a special-purpose service such as Internet gaming or videoconferencing. DMZ hosting forwards all the
ports at the same time to one PC. The Port 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 so the Internet can see it.
Any PC whose port is being forwarded must should have a new static IP address assigned to it because
its IP address may change when using the DHCP function.
DMZ Host IP Address: To expose one PC to the Internet, select Enable and enter the computer’s IP
address in the DMZ Host IP Address field. To disable the DMZ, keep the default setting: Disable.
