Wireguard VPN

Wireguard VPN (wg-vpn) is an ultra-light implementation of a simplified configuration service for Wireguard deployments, designed for use with Linux clients.

Overview

wg-vpn makes use of Wireguard, which is a lightweight, fast, secure, and relatively new Virtual Private Network (VPN), that supports IPv4 and IPv6 connections. The encryption in Wireguard works by utilizing public and private keys to establish an encrypted "tunnel".

Administrator Documentation

The Wireguard VPN service is deployable by an administrator to any VM cloud instance using an Ansible playbook. It serves as a great companion to the wg-quick script and wg VPN.

Deployment Topology

The following diagram illustrates the deployment topology for wg-vpn.

Please refer to the technical documentation for how to deploy the wg-vpn server to production or to a local VM for testing.

Client Documentation

The Wireguard VPN service allows users (also known as peers) to self-register and configure their client instances to make use of the wg-vpn virtual private network.

Setup Procedure for Clients

• Users self-register by visiting vpn.my.domain. The user will presented with the following screen.

• The Administrator would have provided the User with a TOKEN which then is pasted into the landing page and GENERATE will generate a one line script like the one below for the user to copy and execute on their local PC.

curl -sSL -H "Authorization: Bearer TOKEN" https://vpn.my.domain/register -o wg-vpn-installer.sh && bash wg-vpn-installer.sh

• This will install and tether wg-vpn to the server vpn.my.domain.

The installation includes the necessary dependencies, wg and wg-quick, and configures the ~/.wireguard/wg0.conf file.

After executing the script, users can see the capabilities of the application by executing wg-vpn --help.
