You need to modify the firewall settings to allow traffic through fixed TCP/IP port.

1. Ensure that no other software or service is using the ports that you are about to set fixed.

   Use the command line command netstat -anp TCP to find out which ports are in use.

   The numbers in the Local Address column after the colon (:) are the port numbers that are in use.

   

2. Browse for tekla.lic, and open it using a text editor.

   By default, the path is ..\Tekla\License\Server.

3. To set a fixed port for lmgrd.exe, enter the TCP/IP port number at the end of the SERVER row.

   The Automatic installation option sets the port to 27007.

   

4. Enter the text port=free_port at the end of the VENDOR row, for example, port=1234.

   

   Defining the TCP/IP port number on the VENDOR row may slow down the restart time of Tekla Licensing Service.

5. Save the changes and close tekla.lic.
6. Update your license server with the changes:
   1. Go to Tekla Licensing > LMTOOLS through the Start menu or Start screen, depending on your Windows operating system.
   2. On the Service/License File tab, ensure that Configuration using services and Tekla Licensing Service are selected.

      

   3. Go to the Start/Stop/Reread tab and click Stop Server to stop the license server, and then start the server again by clicking Start Server.
7. Click the Windows logo key on your keyboard to show the Start menu or Start screen, depending on the operating system.
8. Type wf.msc and press Enter.
   The Windows Firewall with Advance Security MMS snap-in is displayed.
9. In the navigation tree, select Inbound Rule, and then in the Actions pane, click New Rule.

   

10. On the Rule type panel, select Port and then click Next.

    

11. On the Protocol and Ports panel, select TCP, enter the TCP/IP port numbers that you set in steps 3 and 4 in Specific local ports, and then click Next.

    

12. On the Action panel, select Allow the connection, and then click Next.
    
13. On the Profile panel, select the appropriate profiles, and then click Next.

    

14. On the Name panel, enter the name of the rule, and then click Finish.
