Setup your Own VPN With WireGuard on Ubuntu Server

WireGuard is a free and open-source virtual private network (VPN) protocol. It is designed to be simple, fast, and secure, while providing advanced features such as forward secrecy and no logging.

A VPN allows you to securely connect to a remote network over the internet. When you use a VPN, all of your internet traffic is routed through an encrypted tunnel to the VPN server. This helps protect your privacy and security, as well as allow you to access content that may be restricted in your region.

WireGuard is unique compared to other VPN protocols in that it focuses on simplicity and speed. The codebase is small and easy to understand, making it more secure and easier to maintain than other VPN protocols. Additionally, WireGuard is optimized for modern hardware and can deliver high-speed VPN connections.

WireGuard can be used on a variety of operating systems, including Linux, Windows, macOS, and mobile devices running iOS and Android.

To set up WireGuard on an your Ubuntu server, follow these steps:

  1. Install the WireGuard packages:
sudo apt update
sudo apt install wireguard

2. Create a new configuration file:

sudo nano /etc/wireguard/wg0.conf

3. Add the following sample configuration to the file (modify as needed):

[Interface]
Address = 10.0.0.1/24
ListenPort = 51820
PrivateKey = <server private key>

[Peer]
PublicKey = <client public key>
AllowedIPs = 10.0.0.2/32

4. Replace the placeholder values with your own values for the server private key and client public key. You can generate a private key using the following command:

wg genkey
  1. Start the WireGuard interface:
sudo wg-quick up wg0

6. Add the necessary firewall rules:

sudo ufw allow 51820/udp
sudo ufw enable
  1. Repeat the steps 3 to 6 for each additional client you wish to add.
  1. Verify the status of the WireGuard interface using the following command:
sudo wg show

Note: These steps provide a basic setup for WireGuard. For a more secure setup, it is recommended to use a VPN provider or consult the official documentation for additional security measures.
