How do I have to setup my firewall, if the CodeMeter Licenser Server service is blocked?

Share:

Communication between protected applications and CodeMeter License Server (runtime) is based on the TCP/IP protocol. The communication default port is 22350 unless the port has been configured differently in CodeMeter WebAdmin.

If a firewall is active on your computer, you must open port 22350 for TCP and UDP. If your firewall filters the traffic using the application name, you must unblock the CodeMeter License Server service 'CodeMeter.exe'. You can find the application in the directory %Program Files (x86)%\CodeMeter\Runtime\bin. For your firewall define the 'CodeMeter.exe' service as exception.

Please note also that some anti-virus programs feature firewall functions. If you are uncertain, please contact the relevant vendor.
