By default, stunnel is not allowed to start automatically. When everything works, start it as a service for continuous operations. Be aware that it should be launched with "stunnel4" command, not stunnel. I'm using port 81 here to leave standard HTTP port available.įor troubleshooting configuration, you should start stunnel from a command prompt with the "foreground = yes" parameter in its configuration.

The section is where the decapsulation happens : traffic is received as SSL on port 81 and resent to the target server on the RDP port. The 3 commented lines are debug parameters that can be used to troubleshoot the configuration.

Update the configuration file as folllowing chroot = /var/lib/stunnel4/ Sudo cp /usr/share/doc/stunnel4/examples/nf-sample /etc/stunnel/nf

Create a certificate using the configuration file.

OrganizationalUnitName = Organizational Unit Name (eg, section)Ġ.commonName = Common Name (FQDN of your server) OrganizationName_default = My Organization OrganizationName = Organization Name (eg, company) StateOrProvinceName = State or Province Name (full name) ĬountryName = Country Name (2 letter code) We're not going to fully check them, their only use will be to encrypt the tunnel, not to secure the communication : we're tunneling RDP which is itself encrypted and reasonably protected. It doesn't protect the private key, so it's potentailly vulnerable. The following is a basic default configuration to generate SSL certificates with openssl.

Create a certificate configuration file.

If you don't use a gateway at all or use a Windows gateway, stunnel is available on Windows and can be installed as a service to start automatically.

Use one of the non official patch to allow multiple RDP connection on Windows client if you feel the need (this is not allowed by the product license.)

stunnel can then finally send the packet to the server_private_address:3389 port.Ĭheck that the users used for remote connection all have a password.The router routes the request to the gateway port 81, where stunnel can decapsulate the RDP traffic from HTTPS.The data can then go through the proxy, the internet and to the router port 443 in the server network.socat is necessary because stunnel doesn't support socks proxies natively. Still on the client, socat utility is used to redirect locahost:81 to server_public_address:443 through proxy.On the client, stunnel intercepts port 3390 traffic and encapsulate it into HTTPS and redirect it to localhost:81.On the client, the RDP client is started with a target address of localhost:3390.The end to end connexion chain will be this one : On the client side, there's a proxy server with HTTPS proxying (if there's no proxy, there's not much reason to tunnel.).

The client is typically a PC (or any device with RDP client and stunnel available) with which you want to access to the server PC.The traffic needs to be routed from the router to the gateway then to the server. The last component on the server network is the network router/NAT used to connect to the internet (DSL box).I use this always-on gateway for several other purposes, one being waking up the other machines on the network with wakeonlan. stunnel can be hosted directly on the server PC also (open relevant port on the firewall also). This server will run the stunnel utility. On this network, I also use a Ubuntu server as gateway.Remote connections have to be enabled in the computer properties of that machine, and the local firewall adjusted for corresponding traffic (TCP 3389). The server is the PC you want to connect to (typically your home PC).I use it for connections to my home PC from work. It served the same purpose as the Microsoft RDP gateway, but without requirements for Windows Server and licences. Stunnel utility can be used to tunnel RDP connexions through HTTPS/SSL in order to pass through proxies.
