If one were running a ZeroTier client behind a strict implicit-deny-any-outbound firewall, what domains/IPs/ports/protocols would have to be allowed for initial connection to the peering services?
I understand that outbound UDP 9993 would be necessary, but if the node can’t even reach ZeroTier central, that’s not as relevant.
Is there a list of domains/IPs that would have to be explicitly allowed for operation?
