DESCRIPTION
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 VMG 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.
