If you want Supremo to work correctly, it is necessary to allow outgoing traffic to TCP port 5938 and to the following FQDNs on port 443:
- license.nanosystems.it
- dispatcher.nanosystems.it
- onlinestatus.nanosystems.it
- banner.nanosystems.it
- console.supremocontrol.com
- ecommerce.nanosystems.it
If the operating system in use is Windows Xp / Windows Vista, it is necessary to allow outgoing traffic also towards TCP port 80.
If the operating system is macOS, iOS (on Iphone / Ipad) or Android, it is necessary to allow outgoing traffic to * .nanosystems.it, *.supremocontrol.com on TCP port 443.
It is necessary that the firewall or router supports reverse DNS functionality.
