![]() On the left side, in the Category window, go to Connection. Launch PuTTY and enter the hostname ( .![]() SSH doesn't care what protocol it uses for the tunnels, so you can theoretically access IPv6 only hosts from an IPv4 only system, given that the ssh server is dual stack (has both IPv4 and IPv6 addresses. Creating an SSH Proxy Tunnel with PuTTY 1. On Gateway1, ssh -L 127.0.0.1:15900:VNCServerIP:5900 Once the ssh to Gateway2 is up, attempt to vnc to 127.0.0.1:15900 - you should now see the VNC screen on the far side!ĪDDED BONUS - not many people know this, but this process can also be used to proxy IPv6/IPv4 traffic as well.Connect (if not already connected) to Gateway1.Create a tunnel with local source 15900, and remote source 127.0.0.1:15900.Head over to the tunnels panel in Putty (Connections->SSH->Tunnels accessed either from the context menu if the ssh session is already active, or in the beginning connection screen when just starting putty).You'll still need to do a few ssh connects, but you'll be able to cross vnc or rdp directly from the windows system once you're set, which is what I believe you're looking to do. If you then setup a port tunnel on your intermediate box, setting up the local port you specified as the remote port in putty, you can then bounce through your putty, through the intermediate box your final destination. Be sure to click "Add", then "Apply." At this point, when you rdp to 127.0.0.1:7789, you'll then connect to 1.2.3.4:3389 over the putty session. To add a tunnel, enter a port number into the source port field (1435 in our example) this is the port on the local machine you. For instance, when I'm trying to RDP to a desktop at my house, I'll generally choose a random local port, something like 7789, then put the local ip address of the desktop (1.2.3.4:3389) as the remote host. Local tunnels produce a localhost port opening on your windows machine that remotes to the ip address and port you specify. Putty does support ssh tunnels, if you expand the Connection, SSH tree, you'll see an entry for tunnels.
