DESCRIPTION
This field shows the WAN interface through which the service is
forwarded.
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.
