3.3.2 Special Applications (Port Triggering)

Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and others. These applications cannot work with simple Network Address Translation (NAT) rules. In this page, you can configure the Router to open certain TCP or UDP ports in order to make these applications work. Note: The range of the router ports is 1 to 65535.

	Application function. Select a PC from here if you do not know

	on the drop-down menu, select the option “Refresh” and you will
