3.1.2.2 Port Triggering
Some applications require multiple connections, like Internet games, Video conferencing,
Internet telephony, etc. Because of the firewall function, these applications cannot work
with a pure NAT router.
The Special Applications
feature allows some of these
applications to work with this product. If the mechanism of Special Applications fails to
make an application work, try setting your computer as the DMZ host instead.
This device provides some predefined settings. Select your application and click
“
Copy
to”
to add the predefined setting to your list.
1.
Trigger:
The outbound port number issued by the application.
2.
Incoming Ports
: When the trigger packet is detected, the inbound packets sent to the
specified port numbers are allowed to pass through the firewall.
Afterwards, Click on “Save” to store your settings or click “Undo” to give up the changes.
