4.7 Special AP
Some applications require multiple connections, such as 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 your Barricade. If the mechanism of Special Applications
fails to make an application work, try setting your computer as the DMZ host instead.
1. Trigger: the outbound port number issued by the application.
2. Incoming Ports: when the trigger packet is detected, inbound packets sent to the
specified port numbers are allowed to pass through the firewall.
This product provides some predefined settings. Select your application and click Copy to
to add the predefined setting to your list.
Note: At any given time, only one PC can use each Special Application.
