Tools

sshttp (SSH/HTTP(S) multiplexer)

bypassing firewall rules, protocol multiplexing

This tool allows you to run a web server and SSH daemon on the same TCP port. It can be useful to bypass some firewall restrictions.

sslh (SSL/SSH multiplexer)

bypassing firewall rules, protocol multiplexing

A typical use case for multiplexing is to allow serving several services on one port. Port 443 is commonly used, as that is typically opened on firewalls to allow HTTPS traffic. By multiplexing it, you can also use SSH or other services on the same port.
