Setting up your own PSE OpenVPN server might sound intimidating, but don't worry, guys! This guide breaks it down into simple, manageable steps. Whether you're looking to enhance your online security, bypass geographical restrictions, or just want a more private browsing experience, this is for you. Let's dive in!

What is OpenVPN and Why Use It?

Before we jump into the setup, let's quickly cover what OpenVPN is and why it's a great choice for creating a secure tunnel for your internet traffic. OpenVPN is an open-source VPN protocol that creates a secure point-to-point or site-to-site connection. Unlike some other VPN protocols, OpenVPN is highly configurable and supports a wide range of security algorithms. This flexibility makes it a favorite among security-conscious users.

Why use OpenVPN? Well, for starters, it offers robust encryption, protecting your data from prying eyes, especially on public Wi-Fi networks. Think of it as creating your own private, encrypted tunnel through the internet. Secondly, it can help you bypass geographical restrictions, allowing you to access content that might be blocked in your region. Streaming your favorite shows from abroad? OpenVPN can help with that! Also, for businesses, OpenVPN provides a secure way for employees to access internal networks remotely, safeguarding sensitive company data.

OpenVPN is compatible with a wide array of operating systems, including Windows, macOS, Linux, Android, and iOS. This means you can secure all your devices with the same VPN server. Plus, because it's open-source, the code is constantly being reviewed by the community, making it more secure and reliable than proprietary solutions. Understanding the fundamentals of OpenVPN makes the setup process more meaningful, as you'll appreciate the security and flexibility it brings to your online activities. Now, let's get our hands dirty and start setting up our PSE OpenVPN server! The process involves a few key steps, including choosing a server, installing OpenVPN, configuring the server, generating certificates, and connecting your client devices. Don't worry, we'll walk through each step in detail.

Choosing a Server

The foundation of your PSE OpenVPN server is, of course, the server itself! You have a couple of options here, and your choice will largely depend on your technical expertise and budget. You could go for a cloud-based virtual private server (VPS), which is generally the easiest and most cost-effective option. Providers like DigitalOcean, Vultr, and Amazon AWS offer VPS instances that are perfect for running OpenVPN. These VPS providers offer different tiers of servers that allow you to choose one that fits your needs. Consider what you want to use the VPN for to find the server that fits your needs. The other path you could go is to find a dedicated server for yourself. This is usually for larger entities like businesses. This is a more costly option and requires more technical understanding to set up, configure and maintain. For most users, a cloud-based VPS is the way to go.

When selecting a VPS, consider factors such as the server's location, CPU, RAM, storage, and bandwidth. Choose a location that's geographically close to you or the content you want to access. More CPU and RAM will ensure smooth performance, especially if you plan to have multiple users connected simultaneously. Adequate storage is needed for logs and configuration files, while sufficient bandwidth is crucial for fast and reliable VPN speeds. A good starting point is a VPS with at least 1GB of RAM, 20GB of storage, and 1TB of bandwidth. Most providers offer hourly or monthly billing, giving you the flexibility to scale your resources as needed.

Once you've chosen your VPS provider, sign up for an account and deploy a new server instance. For the operating system, Ubuntu Server is a popular and well-supported choice. It's lightweight, secure, and has a large community, making it easy to find help and resources if you run into any issues. After deploying the server, you'll receive an IP address and login credentials. Use SSH (Secure Shell) to connect to your server from your local computer. On Windows, you can use PuTTY, while macOS and Linux have SSH built-in. Once connected, you're ready to start installing and configuring OpenVPN!

Installing OpenVPN

Now that you have your server up and running, it's time to install OpenVPN. The easiest way to install OpenVPN on Ubuntu is by using the apt package manager. First, update the package list by running sudo apt update in your SSH terminal. This ensures that you have the latest package information.

Next, install the openvpn package along with the easy-rsa package, which is used for generating certificates. Run the command sudo apt install openvpn easy-rsa. This command will download and install the necessary files and dependencies. During the installation, you might be prompted to configure certain settings. In most cases, the default settings are sufficient for a basic OpenVPN server setup. Once the installation is complete, verify that OpenVPN is installed correctly by checking its version. Run openvpn --version to display the installed OpenVPN version.

After verifying the installation, you need to configure the easy-rsa scripts to create the certificates required for secure communication between the server and clients. Copy the easy-rsa directory to /etc/openvpn directory by running sudo cp -r /usr/share/easy-rsa /etc/openvpn. This ensures that the scripts are located in the OpenVPN configuration directory. Next, navigate to the easy-rsa directory using cd /etc/openvpn/easy-rsa. Before generating certificates, you need to initialize the Public Key Infrastructure (PKI). Run ./easyrsa init-pki to create the necessary directories and files for storing certificates. This step prepares the environment for generating the server and client certificates. With OpenVPN installed and easy-rsa configured, you're ready to move on to configuring the OpenVPN server itself. The configuration involves setting up the server configuration file, generating the server and client certificates, and configuring the firewall. These steps are crucial for creating a secure and functional VPN server.

Configuring the Server

The heart of your OpenVPN server is its configuration file. This file tells OpenVPN how to operate, which ports to listen on, what encryption settings to use, and more. Let's create and configure this file. First, copy the sample OpenVPN configuration file to /etc/openvpn/server.conf by running sudo cp /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz /etc/openvpn/. Then, unzip the file using sudo gunzip /etc/openvpn/server.conf.gz. Now, you can edit the configuration file using a text editor like nano. Run sudo nano /etc/openvpn/server.conf to open the file.

Inside the server.conf file, you'll find many options. Let's go through some of the important ones. First, uncomment the `push
