Why not just go to Screen Sharing->Preferences and choose encrypt all data? Wouldn't that enable you to be able to just enter vnc://remoteaddress in the connect to server dialog and get a secure connection without having to go through all the rigamarole of setting up an SSH tunnel? Or am I missing something here?

Where is Screen Sharing -> Preferences?

I cannot find that anywhere?

If you go to System Preferences -> Sharing -> Screen Sharing -> Computer Settings. There is no encrypt all option?

run /System/Library/CoreServices/Screen Sharing.app
then go to preferences and encrypt all.

Thanks

What your missing is that not all (often corporate) firewalls are enabled to allow port 5900 to pass through. I have this situation -- I can only get through port 22 to my machine at the office, not port 5900. The tunnel allows me to do remote screen sharing with this machine (which, if anyone is concerned, is just fine with my workplaces IT people).

The extra encryption isn't the only reason for using tunnelling. Getting around firewalls in a secure manner is just as (and probably more) important.
