There is an option to connect to the License Server through the Global Internet.
The License Server uses two ports - the Server port (range 27000-27010), and the Vendor port. The vendor's port is "floating" and changes with each restart of the License Server service, but at the time of installation of the License Server, it can be set as permanent (by client choice):
In order for the License Server to be available for Internet connection, it must be installed on a machine with a permanent external IP address, and then both ports of the License Server must be "Forwarded". It's better to contact the IT department for this issue.
To connect users from the global network, it's necessary to enter not only the external (important!) IP address of the server machine in the Registration Wizard, but also the Server port (default is 27000). It will look something like this - 27000@External_IP_Address, for example 27000@115.213.175.11
