Hi Giordix,
Hope you are keeping well.
In our license manager/Admin Control Center (ACC), broadcast connection uses same subnet that machine have.
When selected, enables this machine to search for remote Sentinel License Managers on the local network via broadcasts. (Note that the broadcast uses a random UDP port. This may be an issue with certain firewalls.)
TCP uses unique port no. that is 1947.
Thank You,
Anubhav
