Connecting via WireGuard

Introduction

WireGuard is a tunneling protocol that lets you establish a secure connection, either directly to another host, or to another network or subsection thereof. This can be utilized as a VPN or as a secure entry into another network for accessing storage or other services.

This article is a short walk-through of deploying a wireguard configuration you get from me to access one or more services in my homelab.

Prerequisites

  • A WireGuard config file, archive with password;
  • The password for the archive;
  • A Linux machine.

If you do not have such a WireGuard config archive or the password, contact me.

Installing dependencies

Since WireGuard comes with the kernel, we will only need to install some utilities.

On Debian

sudo apt install wireguard-tools p7zip

On Arch Linux

sudo pacman -S wireguard-tools 7zip

Unpacking the config

This requires a password. You either have received the password already, or will receive it from me via a channel separate to the one I used to give you the archive.

This requires 7z installed:

7z x wg.7z

You should see a file akin to WG-<numbers>-<description>-<name>.conf.

Move the file to your WireGuard directory:

sudo mv WG-98-NAS-Example.conf /etc/wireguard/wg1.conf

You can choose any name for the destination file; just make sure it's a legal network interface name.
The below file name would result in a network interface called wg1.

Connecting

Assuming you named the file wg1.conf:

wg-quick up wg1

And you're done!
