What is sslh
sslh accepts connections on specified ports, and forwards them further based on tests performed on the first data packet sent by the remote client.

A typical use case is to allow serving several services on port 443 (e.g. to connect to ssh from inside a corporate firewall, which almost never block port 443) while still serving HTTPS on that port. Hence sslh acts as a protocol multiplexer, or a switchboard. Its name comes from its original function to serve SSH and HTTPS on the same port.
