5-10 Protecting Your Network
To configure Port Triggering:
1. In the Trigger Range, enter the outbound
ports that will be monitored for activity.
This will be the “trigger”.
2. In the Target Range, enter the inbound ports
that should be forwarded when the trigger
occurs.
3. Select the appropriate protocol: TCP, UDP
or Both.
4. Check the Enable box
5. Click Apply .
To clear a Port Triggering rule, you can either
remove the check from the Enable box, to
temporarily disable the rule, or you can select
the rule and click Delete.

Setting Up A Default DMZ Host
The Default DMZ Server feature is helpful when using some online games and videoconferencing
applications that are incompatible with NAT. The gateway is programmed to recognize some of
these applications and to work properly with them, but there are other applications that may not
function well. In some cases, one local PC can run the application properly if that PC’s IP address
is entered as the Default DMZ Host.
Note: For security, you should avoid using the Default DMZ Server feature. When a
computer is designated as the Default DMZ Server, it loses much of the protection of the
firewall, and is exposed to many exploits from the Internet. If compromised, the
computer can be used to attack your network.
