Which ports are used by Modeler?
If there is a firewall between the Modeler client and server, the firewall must allow use of the following ports:
1433 - port number for the SQL Server instance, sqlservr.exe
1434 - port number for UPD connections to the Microsoft SQL Server Browser service, sqlbrowser.exe
27000 - port number for the PTC Integrity Modeler License Server service. This port number can be changed by adding a new port number to the end of the SERVER line in the floating license file.
For more information about the ports that Modeler uses, see Executables that use ports and their protocols in Integrity Modeler on the PTC eSupport.
