VPN confusion

I found your article on securing your VPN (May 2022 issue) interesting, but I’m slightly confused about WireGuard VPN. Do I have to install this software on my network server, or can I run it just on a desktop or laptop? WireGuard’s website is confusing too. On the subject of browser fingerprinting, couldn’t I just use my DuckDuckGo browser? I would greatly appreciate any information.

THE DOCTOR RESPONDS: Jonni Bidwell’s guide to building your own VPN connection should be required reading for anyone wanting to know what a VPN does, what protection it offers, and importantly, what it doesn’t offer.

The key thing about VPNs is that there are two basic types: client-based, where you encrypt your internet connection using a third-party provider, and server-based, where you configure a VPN server on your home network. This then allows you to ‘dial in’ securely and connect to your local network while away from home. Once connected, you have full access to the network and its resources, shared folders, and printers as if you’re at home.

Jonni’s instructions reveal how to build this type of VPN connection using WireGuard. If you wish to encrypt your internet connection when connected to a public Wi-Fi network, you need a VPN provider that offers Wireguard as a protocol, such as NordVPN, WindScribe, or CyberGhost.

If you’re looking to create a VPN server, you’ll need to install this on your home network—typically on a device that’s on 24/7, which can be a file server on your network or (if supported) your router. Check your router’s instructions to see if it supports acting as a VPN server and what protocols it supports—right now, few routers support WireGuard.
