The port trigger indicates that a specific Extranet port is automatically enabled when a
corresponding Intranet port sends a packet and the packet is mapped to the Intranet port on the
host.A specific mapping packet is sent from the ONT through the Intranet so that specific packets
of the Extranet can be mapped to the corresponding host. A specified port on the gateway firewall
is open to some applications for remote access. The port trigger can dynamically enable the open
port of the firewall.
