Build Your Own VPN

COSTFrom around £4/month TIME30-45 minutes DIFFICULTYBeginner

What you will end up with

A personal VPN server that routes your phone or laptop’s traffic through a VPS you control, rather than through a commercial VPN provider’s infrastructure. Useful for securing traffic on public WiFi, reaching devices on your home network while away, or simply not handing your browsing to a third party.

What it is built from

  • A VPS – 1 vCPU and 512MB RAM is enough; LumaDock‘s smallest tier covers this comfortably
  • WireGuard – the VPN software itself

The shape of the build

  1. Provision a small VPS running Ubuntu or Debian
  2. Install WireGuard from the distribution’s package manager
  3. Generate a key pair for the server and one per device
  4. Write a short server config and a matching client config per device
  5. Open one UDP port on the VPS firewall and connect

Cost

A budget VPS tier covers this with room to spare – WireGuard’s resource use is small enough that the same server can comfortably run several other lightweight services alongside it later.

Security considerations

Disable password-based SSH login on the VPS and use key-based authentication only – the VPN is only as secure as the server hosting it. Keep each device’s private key on that device only; never transmit a private key over email or chat.

Backup considerations

The whole setup lives in a handful of text files under /etc/wireguard/. Keep a copy somewhere safe and the entire server can be rebuilt on a fresh VPS in minutes if needed.

Frequently Asked Questions

Do I need any networking experience?

Basic comfort with the command line is enough. The configuration is short and the same for almost everyone.

Which VPS provider should I use?

Any provider with a basic Ubuntu or Debian image works. We use LumaDock for our own infrastructure.

Can I use this on multiple devices?

Yes - each device (phone, laptop, router) gets its own WireGuard key pair and its own short config block on the server.
