I am about to setup a Zerotier network with one ‘master server’ containing applications that needs to communicate with a lot of clients. (At this point, all Windows 10). That’s pretty strait forward, everyone can communicate with everyone.
My challenge is, that clients should NOT be allowed to communicate with other clients - Only to the master-server. How do I achieve that? As far as I can see, there is no firewall in the Zerotier Central?
Is this only possible to prevent with client-firewalls? Or can I do this in another way, by creating the Zerotier network structure in a specific way?
