Port Triggering
The feature is similar to the virtual server, but utilizes a more secure way to provide
your device. It opens up the port hole temporarily 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, then the device will allow the remote parties to establish
a connection with that PC in LAN.
