Indeed, both the name and the very clever combination of existing components sounded familiar when I first heard about Tailscale :)

Interesting. Sshuttle is great. I've used that a couple of times to create a simple vpn without having to deal with openvpn. Simple and effective.

that's a bit worrying

there's a rather large misunderstanding on its github page:

> You can't use openssh's PermitTunnel feature because it's disabled by default on openssh servers; plus it does TCP-over-TCP, which has terrible performance.

it doesn't do TCP over TCP, it's a bytestream over TCP (exactly the same as shuttle)

something like OpenVPN running in TCP mode would be TCP over TCP
