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.
