This object configures the public port number, restricted to the range 51921-56250 to avoid overlap with other applications, used by a PAT-Bind entry; when portType is cpemgr or cpemgrsecure, this represents the first port in a reserved consecutive block. An admin sets this to the externally-facing port that will be forwarded to an internal host and port. For example, an admin forwarding a single service might set this to 52000, or use it as the base port when configuring a cpemgr wildcard block covering several well-known services.
