VPN's are to setup private connections, sorry I didn't see the watchdog program, but you would not be able to setup a VPN to your bank or anything like that! As Chris says it's browser based and would use SSL, VPN's are used for connections to other networks i.e. your company's network, you go home with a VPN client on your laptop and then log in, so you can access data on that network. What exactly would you want a VPN at home for? What is your current setup? You want to connect to a machine in your office (which is attached to a different network)?
