Previously the documentation said that the client connects out over 9993/UDP and then randomized high numbered UDP ports. But it seems that has changed recently and now the documentation (FAQ | ZeroTier Documentation) States 9993/TCP as the only outbound port needed to connect to ZeroTier services. Is this correct? Was this a recent change?
What are you looking at in the FAQ specifically? The only mention I see of TCP is mentioning the TCP fallback that occurs if configured. The primary port is still 9993/UDP.
These are the normal UDP ports that will be used:
That section was what I was looking at exactly. I couldn’t find any mention of the UDP ports that I used to find so I was a bit confused. Thanks for clearing that up!
