DESCRIPTION
The trigger port is a port (or a range of ports) that causes (or triggers) the ZyXEL
Device to record the IP address of the LAN computer that sent the traffic to a
server on the WAN.
This is the first port number that identifies a service.
This is the last port number that identifies a service.
This is the trigger transport layer protocol.
The open port is a port (or a range of ports) that a server on the WAN uses when
it sends out a particular service. The ZyXEL Device forwards the traffic with this
port (or range of ports) to the client computer on the LAN that requested the
service.
This is the first port number that identifies a service.
This is the last port number that identifies a service.
This is the open transport layer protocol.
