stunnel utility can be used to tunnel RDP connexions through HTTPS/SSL in order to pass through proxies. It served the same purpose as the Microsoft RDP gateway, but without requirements for Windows Server and licences. I use it for connections to my home PC from work.
The 2 sides for the RDP connexion are :
- The server side :
- The server is the PC you want to connect to (typically your home PC). Remote connections have to be enabled in the computer properties of that machine, and the local firewall adjusted for corresponding traffic (TCP 3389).
