tcpproxy VS henk

Neat. Kind of like a highly configurable https://github.com/inetaf/tcpproxy

> You can route raw TCP connections by using higher layer protocol matching logic like HTTP properties, SSH, TLS ClientHello info, and more, in composable routes that let you do nearly anything.

How do you foresee such a setup handle QUIC? The encrypted connection-ids, 0RTT handshakes, and roaming client-ip and server-ips make it non trivial to proxy connections transparently.

Not sure if it has a name, but I've seen it called "reverse dialing": https://github.com/inetaf/tcpproxy/issues/8

I run multiple services this way, behind a tcproxy, in a pair of Scaleway Stardust

I also built something similar once when I needed something like ngrok but wanted to use open source:

It has a very similar approach, but uses about a hundred lines of Go instead of nginx. It's based on unix sockets created by SSH reverse tunneling, whose names are used to select the desired subdomain. This makes it possible to add more reverse proxies with just an ssh command, without changing anything on the server. It's also small enough that it's easy to add custom logic such as request logging.
