Chapter 5: Configuring the Wireless-G Broadband Router
The Applications and Gaming Tab - DMZ
Wireless-G Broadband Router with SpeedBooster
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.
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.
Change these settings as described here and click the
Save Settings
button to apply your changes or
Cancel
Changes
to cancel your changes.
