This object configures the internal port number, from the IANA range 1-49151, that inbound forwarded traffic is sent to on the private host; when portType is cpemgr, this instead represents the count of consecutive public ports reserved by the entry. An admin sets this to the actual service port running on the internal host, such as 80 for a web server, unless using the cpemgr wildcard mode. For example, an admin forwarding to an internal web server would set this to 80, matching the server's listening port.
