Application Rules
Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and 
others. These applications have difficulties working through NAT (Network Address Translation). Special Applications 
makes some of these applications work with the DIR-628. If you need to run applications that require multiple connections, 
specify the port normally associated with an application in the “Trigger Port” field, select the protocol type as TCP or 
UDP, then enter the firewall (public) ports associated with the trigger port to open them for inbound traffic.
The DIR-628 provides some predefined applications in the table on the bottom of the web page. Select the application 
you want to use and enable it.
