URBackup Server (on Windows) : Disable Broadcast

Hi!
Just a quick question: is it possible to disable URBackup Server (latest stable) from broadcasting? (running it on Windows 2012)
Thanks!

Any idea?

Windows firewall - prevent the outbound UDP broadcast on port 35622. Reference Administration Manual Section 3.2 Client Architecture.

Thanks @Don_Wright
While this is certanly a solution, I’d think there should be an option to disable it rather than blocking it (sound very inefficient)

See e.g. here: Enable internet only mode

Thanks @uroni
Is there any other side effect on “Internet only mode” besides disabling broadcasts?
