Wireless-G Broadband Router with SpeedBooster
The Applications & Gaming Tab - Port Triggering
The Port Triggering screen allows the Router to watch outgoing data for specific port numbers. The IP address of the computer
that sends the matching data is remembered by the Router, so that when the requested data returns through the Router, the
data is pulled back to the proper computer by way of IP address and port mapping rules.

The Applications and Gaming Tab - DMZ
The DMZ feature allows one network 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 Range Forward 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.
Figure 3-37: Applications and Gaming Tab - DMZ
Any PC whose port is being forwarded must have its DHCP client function disabled and should have a new static IP address
assigned to it because its IP address may change when using the DHCP function.
To expose one PC, select Enable. Then, enter the computer's IP address in the DMZ Host IP Address field.
