It's the one thing when I'm configuring things that makes me wince because I know it will give me the business, and I know it shouldn't, but it does, every time. I have no real idea what I'm doing, what it is, how it works, so of course I'm blindly following instructions like a monkey at a typewriter.
Please guide me into enlightenment.
VPN: you give your mail to a dude who puts it in a plain suitcase and goes with it to the VPN company's HQ. Nobody knows whose mail he's got or where it's headed. When that dude gets to the VPN company's office he gives that envelope to another dude who carries it to the destination. If someone's peeping they can only see the dude going from your place to the VPN place or from the VPN place to the destination, not from your place to the destination.
