The port parameter specifies the TCP/IP port number on which the protocol handler listens for incoming client requests.
On Windows, you can use the ctgservice command with the -port option to override the value of the port parameter. On UNIX and Linux, you can use the ctgstart command with the -port option to override the value of the port parameter. For more information, see the Command reference.
This parameter is in the SSL protocol parameters subsection of the GATEWAY section of the configuration file.
