Wireguard DRY

This guide covers the setup process for a WireGuard VPN server and includes steps to add and manage VPN clients - using ansible. When you add a client you get a zip file and the QR code in the terminal.

Prerequisites

Ensure that you have the following software installed on your system:

• Ansible
• Homebrew (for macOS)
• Python's netaddr package
• devsec.hardening Ansible collection
• community.general Ansible collection

If these are not installed, you can set them up with the following commands:

# Install Homebrew (macOS)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install Ansible
brew install ansible 

# Install devsec.hardening Ansible collection
ansible-galaxy collection install devsec.hardening --force
ansible-galaxy collection install community.general --force

# Install netaddr Python package
pip install netaddr

Setup

Initialize

Initialize the server IP, username, and SSH port.

make init

The make init command will prompt you for the server host, server username, and SSH port (default: 22).

VPN Server Setup

To set up the WireGuard server, run the following command:

make vpn-server-setup

This command will ask you to enter the DNS server (default: 10.99.0.1).

Firewall Setup

Secure the server by blocking external access to sensitive ports (like DNS:53 and Web:8080) while allowing VPN clients and SSH.

make vpn-firewall-setup

Optional: Server Hardening

You can optionally harden your server with the devsec.hardening Ansible collection and the server_hardening.yml playbook.

ansible-galaxy collection install devsec.hardening --force
ansible-playbook -i inventory.ini server_hardening.yml

Managing VPN Clients

To add, remove, list, or generate QR codes for VPN clients, use the following commands:

Add a Client

make vpn-client-add

The command will prompt you to enter the client name.

Remove a Client

make vpn-client-remove

You will need to enter the client name that you want to remove.

List All Clients

make vpn-client-list

Display Client's QR Code

make vpn-client-qrcode

You will be asked to enter the client name whose QR code you want to display.

For further help and a list of all available commands, run make help.
