Port Triggering
The feature is similar to the virtual server, but provides a more secure way to provide your
device. It opens up the port hole temporary and allows CPE in LAN to establish a connection
with remote parties. Those ports are open only if a specified request from a PC in LAN is
received, and then the device allows the remote parties to access to establish a connection
with that PC in LAN.
