There’s a reimplementation of the Tailscale control plane called Headscale, if you want to self-host.
I’d try to use that first, because sadly Nebula and ZeroTier don’t have a relay/TCP/HTTPS fallback option and still “have no plans of implementing one” as of Mar 2023, which leaves you out of luck as soon as you encounter NATs or try to access your cluster from an airport/hotel wifi
Maybe you know of other mesh/p2p VPNs that do support TCP fallback though? Would be great to see some alternatives in this area
I've been using the relay for months. It is very stable BUT, it sometimes takes minutes before peers realize they can also talk to each other on the local network.
Pretty sure ZeroTier supports relaying (I remember reading some of their earlier blogs and it mentioning something to that effect). In practice, you just have to turn off the uPnP in Settings to use it I've found.
