ZeroTier Flow Rules

Networking & Firewalls
1

I’m looking at ZeroTier to potentially use for managing a few servers I have in different locations. Something that I would like to be able to do is restrict those servers from talking to one another but have the ability to allow them to talk to a small set of specified devices that I’ll be doing the management from.

I feel like it may not be too complicated to make happen, but I’ve been wrong before. Hahaha

I did find a set of rules a guy posted from a setup he used at DEFCON one year to do something similar but in the reverse (I think). But, I can’t seem to reverse the rules in a way that gives me the right results we need.

Any thoughts would be appreciated!
