Applications & Gaming > DMZ
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 videoconferencing. 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.
DMZ
Any computer 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.
DMZ To disable DMZ hosting, keep the default, Disabled. To expose one PC, select Enabled.
Then configure the following setting:
DMZ IP Address Enter the IP address of the computer.
Click Save Settings to apply your changes, or click Cancel Changes to cancel your
changes.
Applications & Gaming > Port Range Triggering
The Port Range 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.
Port Range Triggering
To trigger a port range, enter the information on each line for the criteria required.
Application Name Enter the unique application name of the trigger.
Port Start ~ Port End For each application, enter the starting and ending port numbers of the
triggering port number range. These are the ports used by initiating traffic. Check with the
Internet application documentation for the port number(s) needed.
Protocol For each application, select the appropriate protocol, TCP(6) or UDP(17).
Forwarded Port Start ~ Forwarded Port End For each application, enter the starting and ending
port numbers of the forwarded port number range. These are the ports used by incoming traffic.
Check with the Internet application documentation for the port number(s) needed.
Allow Multiple Hosts Select this option to allow multiple hosts in returned traffic.
Enabled Select Enabled to enable port triggering for the applications you have defined.
Click Save Settings to apply your changes, or click Cancel Changes to cancel your
changes.
Applications & Gaming > QoS
Quality of Service (QoS) ensures better service to high-priority types of network traffic,
which may involve demanding, real-time applications, such as videoconferencing.
Note: The Router’s QoS is for upstream traffic regulation only. Downstream QoS is
usually enforced by the service provider’s headend equipment.
