Setting up my own VPN server on Vultr with Centos 7 and WireGuard

As an IT consultant, I travel a lot. I mean, a lot. Part of the pleasure is having to deal with day-to-day online life on open, potentially free-for-all hotel and conference WiFi. In other words, the type of networks you really want to do your online banking, ecommerce and other potentially sensitive operations on. After seeing one too many ads for VPN services on bad late night TV I finally decided I needed to do something about it. Ideally I intended to this on the cheap and learn something in the process. I also didn’t want to spend the whole weekend trying to set it up, which is how WireGuard entered the picture. I only really needed to protect my most sensitive device – my personal travel laptop.

As I’m already a customer at Vultr (affiliate link) I decided to just spin up another of their tiny instances and set it up as my WireGuard VPN server. Note that I’m not setting up a VPN service for the whole family, all my friends and some additional people, all I’m trying to do is secure some of my online communications a little bit more.

I also decided to document this experiment, both for my own reference and in the hope that it will be useful for someone else. Readers will need to have some experience setting up and administering Linux server. Come on in and follow along!
