Build Your Own VPN Server

Build Your Own Secure VPN Server in the Cloud or on a Raspberry Pi

This practical, step-by-step guide shows you how to build your own IPsec (IKEv2), OpenVPN, and WireGuard VPN server. Based on 10 years of open-source development trusted by millions of users worldwide, this book enables you to deploy a secure, reliable VPN server in minutes—even if you have never set up a server before.

By reading this book, you will learn how to:

• Create a cloud server on DigitalOcean, Vultr, Linode, or OVH
• Connect via SSH and install WireGuard, OpenVPN, and IPsec (IKEv2)
• Configure VPN clients on Windows, macOS, Android, and iOS
• Manage WireGuard, OpenVPN, and IPsec VPN clients

In today’s digital world, privacy and cybersecurity are essential. A VPN encrypts your internet traffic, protecting your data from hackers, surveillance, and unsecured public Wi-Fi networks.

Thanks to affordable cloud servers and automation, running your own VPN has never been easier. A self-hosted VPN can cost less than commercial services while giving you full control over your data. By the end of this book, you will have a fully functional VPN server that you control completely.
