Some applications require open service ports, such as Internet games, video conferencing, Internet telephony, and others. When a request is made to the ISP's given address for a specific port, it is forwarded to the machine that is hosting that particular service. These applications cannot work with a pure NAT broadband router since all the ports are blocked by default. This is a result of the broadband router's firewall function. Special Applications will allow some of these applications to work with a NAT broadband router. If the Special Applications still do not allow an application to function correctly, refer to the DMZ host option in the Miscellaneous Items.

1. Trigger: This is the outbound port number that the application assigned first.

2. Incoming Ports: When the trigger packet is detected, the inbound packets to the specified port number are allowed to pass through the firewall.

This product provides some predefined settings in the grey pad on the bottom of the Web Page Interface. Select Popular applications and click Copy to copy a predefined setting.

Note: Only one PC can be assigned a specific port number at one time.
