tcpproxyreflector does exactly what you want. Install it on the 3
computers and run it :

- as a server at home, to get connection from the the client and console
- as the client at work, to open and keep the the connection open with home
- as a console on your laptop at the hotel to activate a tunnel and
connect through SSH or directly on port  "3389" to another computer
inside the company.
