WireGuard VPN and Oracle Cloud

WireGuard VPN is a free and open-source virtual private network technology that provides secure and fast communication between devices over the internet. It uses state-of-the-art cryptography and is designed to be lightweight, efficient, and easy to use. Oracle Cloud is a cloud computing platform that offers a wide range of infrastructure and platform services, including virtual machines, databases, storage, and networking. In this article, we will show you how to host a WireGuard VPN for free with Oracle Cloud.

Setting up a Free Oracle Cloud Account

To set up a free Oracle Cloud account, go to the Oracle Cloud website and click on the “Free Tier” button. This will take you to the sign-up page, where you will need to provide your name, email address, and other details. Once you have signed up, you will receive a confirmation email with instructions on how to log in to your new Oracle Cloud account.

Creating and Configuring Your Virtual Machine

Once you have logged in to your Oracle Cloud account, you can create a virtual machine by clicking on the “Create a VM instance” button. You will need to choose a region, an image, and a shape for your virtual machine. We recommend choosing the “Oracle Linux 8” image and the “VM.Standard.E2.1.Micro” shape, which is the smallest and cheapest option. You can also add some optional features, such as a public IP address or SSH keys, if you need them.

Deploying and Configuring WireGuard on Your Oracle VM

To deploy and configure WireGuard on your Oracle VM, you will need to SSH into your virtual machine and follow these steps:

1. Install WireGuard on your Oracle VM by running the following command: sudo yum install -y kmod-wireguard wireguard-tools
2. Generate a private key and a public key for your Oracle VM by running the following command: wg genkey | tee privatekey | wg pubkey > publickey
3. Create a configuration file for WireGuard on your Oracle VM by running the following command: sudo nano /etc/wireguard/wg0.conf and copy the following template into it:

[Interface]
PrivateKey = 
Address = 10.0.0.1/24
ListenPort = 51820

[Peer]
PublicKey = 
AllowedIPs = 10.0.0.2/32

4. Replace with the private key you generated in step 2, and with the public key of the client device you want to connect to your WireGuard VPN.
5. Save and close the configuration file by pressing CTRL+X and then Y.
6. Start the WireGuard service on your Oracle VM by running the following command: sudo systemctl enable [email protected] && sudo systemctl start [email protected]
7. Verify that WireGuard is running on your Oracle VM by checking the status of the service with the following command: sudo systemctl status [email protected]
