Modeler Server uses only 1 port on Windows

Question

Document 1 and 2 of Modeler says "To configure the range of ports, IBM SPSS Modeler will need two open ports". This doess not match to the product behavior on Windows. Quoted: By default, IBM SPSS Modeler will use any open port that is available; if it does not find one (for example, if they are all closed by a firewall), an error is displayed when you execute the stream. To configure the range of ports, IBM SPSS Modeler will need two open ports (in addition to the main server port) available per concurrent stream, plus 3 additional ports for each ODBC connection from within any connected client (2 ports for the ODBC connection for the duration of that ODBC connection, and an additional temporary port for authentication).
