Port Triggering
Some applications like online games, video conferencing and Internet telephony require multiple connections to the internet. As
such, these applications cannot work with a pure NAT router such as the NB16WV-02.
The Port Triggering feature allows some of these applications to work with this router.
Note: Please check if your application is compatible with port triggering first. If this fails to make the application work, try
to configure that computer as the DMZ host instead. Each port can only be used by 1 host machine at a time. If the port
is occupied by an existing host, port triggering/forwarding/DMZ for that port will not work.
(For further instructions on setting up a DMZ host, please refer to the “Miscellaneous” section below)
OPTION
DEFINITION
Trigger
The outbound port number that will be triggered by the application.
Incoming Ports
When the trigger packet is detected, the inbound packets sent to the specified port numbers will be allowed to pass through the
firewall to the triggering host.
Enable
Select to enable or disable the configured special application entry.
Port triggering opens an incoming port when your computer is using a specified outgoing port for specific traffic.
The NB16WV-02 also provides predefined settings for some popular applications.
To use the predefined settings, select your application from the “Popular applications” drop down list, select an unused ID from
the list and then click Copy to. The predefined settings will then be added to the list.
Click Save to save the settings or Undo to cancel.
