A few years ago, I ran across a great, easy to use product that didn’t cost me a dime. It allows me to work when I am traveling, and to keep tabs on a server that is 60 miles away without moving from this spot. It even allows some of our customers to share network resources, like files and printers between offices that are across town. It’s easy to install, and easy to set up. The company that distributes it gives clear instructions - with screen shots - on how to set up your VPN right on their web site. It’s called Hamachi.
