Okay, I know what WinHand is...

...But their website doesn't say HOW it works.

Is it like GotomyPC where it works through a firewall, or do you need to setup port forwarding on your firewall, and have a static IP address?

I am just looking for a sensible method to connect to my PC, I know VNC is an option but I am not punching holes in my corporate firewall.
