10.5: How to use screen sharing remotely and securely
Authored by: bugmenot on Nov 25, '07 12:50:18AM

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.
