Central management

[SimpleRezo]

I have sent you a PM

I will answer you for your PM, but for everyone else interested, we have created a page describing our solution:
  https://srbox.simplerezo.com/

The solution is internally used for production, and we are just starting Early Access for third parties.

How will be the communication between the centralized administration opnsense and the other opnsenses when I place a centralized device to internet?
Is there e.g. a cyclic polling of configuration possible or do I need a direct reachability from the central device to satelites or can I use a VPN wich is started from the satelite to the central instance?

I need that information too.
Can central administration be done without a public ip at the clients?

Our solution works without a Public IP and any exposed ports
