WireGuard Tunnel Configuration on Windows and Linux

Introduction

WireGuard is a modern, lightweight, and fast VPN protocol.
It allows you to establish an encrypted tunnel between a server and one or more clients, while offering better performance and simpler configuration compared to OpenVPN or IPSec.

In this guide, we will configure a WireGuard tunnel between a Linux server and a client (Linux or Windows).

Prerequisites

• A Linux server (Debian/Ubuntu/CentOS or equivalent) with root/SSH access
• A client machine running Linux or Windows
• Administrator access on the client
• wireguard-tools package or the official WireGuard application installed

WireGuard Installation

On Linux

Update your packages and install WireGuard:

# Debian / Ubuntu
sudo apt update && sudo apt install wireguard -y

# CentOS / RHEL (via EPEL)
sudo yum install epel-release -y
sudo yum install kmod-wireguard wireguard-tools -y
