VPN actually stands for virtual private network. What that means is that when you connect to a VPN, you are essentially creating a secure encrypted tunnel from your device to the network on the other side. A VPN prevents “snooping eyes” from seeing the actual network traffic that crosses the wire, meaning that you only you and the other end know what you are doing. That traffic will be visible from the other end as it comes out there, but that is a network you “trust”, and that traffice is protected as it traverses across the Internet.
You’ve probably heard of VPN services before or you might already use one. They are common for work places to use, to connect back to your office. As well commercial VPN services for individuals looking to bypass geo-location filters when they are overseas to make it appear that you are in the U.S., or users as an attempt to anonymize their internet traffic. Those are all great examples of VPNs. But those are not what I am going to cover….
So what about if you want to access resources you have at home while you are away? (i.e. – printers, file storage or file backups, remote support of a non-tech-savvy family member)
Or what if you want to use the Pi-Hole adblocker you set up at home while your at school/work/traveling?
This is the type of “home VPN” that I am talking about. This “home VPN” will keep your browsing secure while you are hopping onto free WiFi hotspots all across town, but it will not anonymize your traffic at all. All of your traffic is [securely] going to go thru your VPN and it will be as if you are surfing the Internet from home. So don’t think that just because you setup a VPN on your Raspberry Pi at home that you can blindly surf the Internet and download illegal torrents without consequence, because you’d be wrong. You will however, be able to connect back home and retrieve those files you forgot to put on your thumb drive before walking out the door.
The magic that will make it happen is called PiVPN. It’s a small piece of software that can be installed on a Raspberry Pi with a single line of code, and can be configured, ready-to-go, in less time than it take to watch a sitcom episode on Netflix.
