If you don't want to open an extra port for VNC or want extra security with SSH, you can setup an SSH tunnel for VNC. On Windows, you can do this with Putty or openssh . Open a command window, and enter (using Putty as example): C:\local\bin\plink.exe -ssh -2 -L localhost:5901:r... When connecting with vncviewer , use localhost:5901 as server instead of remote_host:5901 . If you use the setup frequently, it is more convenient to setup the tunnel as a Windows service . Assuming the name of the service is vnc_tunnel , the registry entry would look like: Windows Registry Editor Version 5.00 [HKEY_...

I just list them here as a reminder. Is Windows firewall blocking the connection? No. It turned out that, unlike ZoneAlarm , the Windows firewall does not block outgoing traffic. It only blocks incoming requests. Is vncserver listening on the right IP address? Yes. netstat showed it's listening on all NICs. netstat -a | grep 5901 tcp 0 0 *:59...
