–
After a PC has finished using a Port Triggering application, there is a time-out period
before the application can be used by another PC. This is required because the firewall
cannot be sure when the application has terminated.
See
“Setting Up Port Triggering (in NAT mode)” on page 4-31
for the procedure on how to use
this feature.
DMZ Port
The DMZ Port allows you to set up the DMZ port. Specifying a Default DMZ Server allows you to
set up a computer or server that is available to anyone on the Internet for services that you haven't
defined.
The default setting of the rules is that the DMZ port and both inbound and outbound traffic is
disabled. Enabling the DMZ port increases the traffic through the WAN ports.
The quad WAN gigabit firewall makes LAN port 4 a dedicated hardware DMZ port when DMZ is
enabled (see
“Router Front Panel” on page 1-5
See
“Configuring and Enabling the DMZ Port” on page 3-12
for the procedure on how to use this feature.
Using QoS to Shift the Traffic Mix
The QoS priority settings determine the priority and, in turn, the quality of service for the traffic
passing through the firewall. The QoS is set individually for each service.
•
You can accept the default priority defined by the service itself by not changing its QoS
setting.
•
You can change the priority to a higher or lower value than its default setting to give the
service higher or lower priority than it otherwise would have.
The QoS priority settings conform to the IEEE 802.1D-1998 (formerly 802.1p) standard for class
of service tag.
You will not change the WAN bandwidth used by changing any QoS priority settings. But you will
change the mix of traffic through the WAN ports by granting some services a higher priority than
others. The quality of a service is impacted by its QoS setting, however.
See
“Configuring QoS (Quality of Service)” on page 5-26
for the procedure on how to use this
feature.
