Configuring a License Server That Uses a Firewall (Windows) or VPN Access

Floating licenseLicense Management GuideLicense ServerDevelopment Hosts

If your server machine uses a firewall or if you want to access it over a VPN channel, then the server license file and the firewall require additional configuration. The configuration steps you use depend on whether your floating license management environment uses specific or default port numbers. You might need to change the server's license file, the configuration of the firewall, and the configuration of the client machines.

These actions require administrator permissions.

If you're using specific port numbers...

If you're using specific port numbers, you need to adjust the server license file and Microsoft Windows firewall configuration accordingly.

Make the following changes to the server license file: 
SERVER hostname hostid [server_portnumber]
VENDOR qnxlm [PORT=vendor_portnumber]

where:

server_portnumber
The TCP/IP port number the server uses. A valid server TCP/IP port number is any unused port between 0 and 64000. On UNIX-style systems, choose a port number greater than 1024. If you don't specify a port, one in the default range of 27000 to 27009 is used. If you specify a port, we recommend you use one outside of the default range.
vendor_portnumber
The vendor daemon's TCP/IP port. By default, the OS chooses the vendor daemon's TCP/IP port at runtime. This port must be different from server_portnumber.

Make the following changes in the Windows Firewall Options dialog:

  • In the General tab, uncheck Don't allow exceptions.

  • In the Exceptions tab, make one of the following changes:

    • Add Port: vendor_portnumber

    OR

    • Add Program: installation_directory\flexserver\host\win64\x86_64\usr\bin\qnxlm.exe
    • Add Program: installation_directory\flexserver\host\win64\x86_64\usr\bin\lmgrd.exe

If you're using default port numbers...

If you're using default port numbers, no changes to the server license file are required.

However, you still need to make the following changes in the Windows Firewall Options dialog:

  • In the General tab, uncheck Don't allow exceptions.

  • In the Exceptions tab, make the following changes:

    • Add Program: installation_directory\flexserver\host\win64\x86_64\usr\bin\qnxlm.exe
    • Add Program: installation_directory\flexserver\host\win64\x86_64\usr\bin\lmgrd.exe
