Applications and 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.

Triggering
The Port Range Triggering screen allows the Gateway to
watch outgoing data for specific port numbers. The IP
address of the computer that sends the matching data is
remembered by the Gateway, so that when the requested
data returns through the Gateway, the data is pulled back
to the proper computer by way of IP address and port
mapping rules.

Applications and 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 Gateway's QoS is for upstream traffic
regulation only. Downstream QoS is usually
enforced by the service provider's headend
equipment.
