So, how do you embark on this exciting project? Setting up a Raspberry Pi as a VPN server involves several steps, but the process is surprisingly straightforward with the right guidance. There are two popular choices when setting up a VPN on Raspberry Pi. One such method involves using software like PiVPN, which simplifies the installation and configuration process. Alternatively, you can manually configure VPN servers like WireGuard or OpenVPN for greater customization.

Let's delve into the practical aspects. To start, you'll need a Raspberry Pi board (any model from Pi 3 or newer is suitable, though the Raspberry Pi 4 offers the best experience), a power supply, and a microSD card with at least 8GB of storage. It's recommended to use the latest Raspberry Pi OS Lite image for optimal performance. This minimal operating system reduces the load on your Pi, allowing it to focus on its VPN duties.

Once you have the hardware ready, the next step is to install and configure the VPN server software. PiVPN is a popular choice because it automates much of the setup process. It supports both OpenVPN and WireGuard, allowing you to choose the protocol that best suits your needs. OpenVPN is a mature and widely supported protocol, while WireGuard is a more modern option known for its speed and security.

To install PiVPN, you'll need to SSH into your Raspberry Pi and run the installation script. The script will guide you through the configuration process, asking you to choose your VPN protocol, configure DNS settings, and create user accounts. Once the installation is complete, you'll have a fully functional VPN server running on your Raspberry Pi.

Another approach involves using the Twingate connector. The Twingate connector is a piece of software that allows for secure access to your remote network and the devices connected to it (in this case, your Raspberry Pi). For it to work, you first need to deploy the connector on your Raspberry Pi.

Now, let's discuss accessing your local network via WireGuard. To allow VPN clients to access devices on the local network (e.g., 192.168.0.0/24), add the following post-up and pre-down rules to the WireGuard server configuration (wg0.conf), set up the client to route local network traffic through WireGuard, and specify DNS settings if needed.

A more radical option is to access your Raspberry Pi through a VPN. VPN stands for virtual private network and allows you to access remotely all services on your Raspberry Pi as if you were in the local network. All traffic between you and the Raspberry Pi will be encrypted by a strong protocol.

Once your VPN server is up and running, you'll need to configure your client devices to connect to it. This involves installing a VPN client on your computer, smartphone, or tablet and importing the configuration file generated by PiVPN. The configuration file contains the necessary information to establish a secure connection to your Raspberry Pi VPN server.

With the VPN client configured, you can now connect to your home network from anywhere in the world. All traffic between your device and your Raspberry Pi will be encrypted, protecting your data from prying eyes. This is especially useful when using public Wi-Fi networks, which are often insecure.

But setting up a VPN is just the first step. Like any good fortress, your Raspberry Pi VPN needs regular maintenance and security checks. Start by ensuring your Raspberry Pi has an updated operating system. Outdated software is like leaving a window open for cyber threats. Regularly update your Raspberry Pi OS and VPN server software to patch any security vulnerabilities.

It's also important to monitor the performance and stability of your VPN. This includes tracking bandwidth utilization, connection status, and server resource usage. Tools like `top`, `htop`, and `vnstat` can help you monitor your Raspberry Pi's performance. Additionally, consider setting up logging to track VPN connections and identify any potential issues.

To further enhance the security of your Raspberry Pi VPN, consider implementing additional security measures. For example, you can enable two-factor authentication (2FA) for VPN user accounts. This adds an extra layer of protection, making it more difficult for unauthorized users to gain access to your network.

Another security measure is to configure a firewall on your Raspberry Pi. A firewall acts as a barrier between your network and the outside world, blocking unauthorized access attempts. You can use tools like `iptables` or `ufw` to configure a firewall on your Raspberry Pi.

For those seeking an alternative approach, setting up Tailscale VPN offers secure, remote access to your Raspberry Pi over the internet. This method provides a simplified and user-friendly experience for establishing a secure connection.

Beyond secure remote access, a Raspberry Pi VPN unlocks a world of possibilities. You can use it to bypass geo-restrictions and access content that is not available in your region. You can also use it to protect your privacy when browsing the web or using public Wi-Fi networks. Additionally, a Raspberry Pi VPN can be used to create a secure tunnel between two networks, allowing you to access resources on both networks simultaneously.

If you have a Raspberry Pi running most of the time at home, setting up a VPN server on it might be a great way to keep access to your home network from anywhere. WireGuard is a modern, secure, and performant VPN solution that can be installed on a Raspberry Pi. However, setting up the Pi as a VPN server can be complex.

So, in this tutorial, we will set up the Pi as a VPN gateway using a VPN client that supports OpenVPN. The Raspberry Pi VPN gateway can be created by first connecting the Raspberry Pi to a VPN provider.

It's also worth noting that you can use PiVPN in any cloud provider VPS running Ubuntu or Debian to assist those with untrustworthy ISPs. This provides an added layer of security and privacy for your internet traffic.

Secure remote access to Raspberry Pi refers to the ability to connect to your device from a remote location while ensuring that the connection is protected from unauthorized access. This process typically involves using encryption protocols, authentication methods, and secure communication channels to safeguard data transmission.

If your router does not support VPN functionality, you can also set up your own VPN, for example, using your Raspberry Pi.

Given your current setup with 2FA enabled for all users and "local use only" for internal users, client certificate authentication is likely not strictly necessary for a reasonably secure Home Assistant setup, but it would add an extra layer of security for remote access if you can overcome the usability issues.

To copy a file named `myfile.txt` from your personal computer to a users home folder on your Raspberry Pi, run the following command from the directory containing `myfile.txt`, replacing the `` placeholder with the username you use to log in to your Raspberry Pi and the `` placeholder with your Raspberry Pis IP address:

`scp myfile.txt @:/home/`

Speaking of remote access, consider the Pi KVM project. Learn how to assemble and configure your Pi KVM using a Raspberry Pi and adjust settings to reduce mouse lag and improve control when using Pi KVM remotely. This allows you to remotely control your Raspberry Pi as if you were physically present.

Now, what if you decide to remove your VPN from your Raspberry Pi? You can simply utilize the following command, which will use the PiVPN software to uninstall the VPN tunnel.

`pivpn uninstall`

To make the most of your Raspberry Pi VPN server, consider some advanced configurations. For instance, you can configure split tunneling, which allows you to route only specific traffic through the VPN while routing other traffic directly to the internet. This can improve performance and reduce bandwidth usage.

You can also configure your Raspberry Pi VPN server to act as a wireless access point. This allows you to create a secure Wi-Fi hotspot that automatically encrypts all traffic passing through it. This is especially useful when traveling or using public Wi-Fi networks.

If you're using WireGuard, you can configure peer-to-peer connections between your devices. This allows you to create a secure tunnel directly between two devices, bypassing the Raspberry Pi VPN server. This can improve performance and reduce latency for specific applications.

Now, let's talk about fortifying your Raspberry Pis security wall. Setting up a VPN on your Raspberry Pi is like building a secret fortress for your data. But even the mightiest fortresses need regular inspections and reinforcements!

Remember, secure remote access to your home network allows you to access files, IoT devices, cameras, and other network resources from anywhere securely. Unleash the power of your Raspberry Pi with these innovative networking projects that will elevate your skills and expand your devices capabilities. Whether it's setting up a VPN server, a wireless access point, or a network monitoring system, the Raspberry Pi is a versatile tool that can help you secure and manage your network.

Now I'm on it, I'll buy a Pi, set up a NAS with Open Media Vault, then set up a VPN and finally access from my two workplaces the same documents. Thanks a lot, I'll keep you updated and maybe will write down the steps for future reference.

Note that this tutorial assumes that you are running the latest Bookworm distribution, which uses the Network Manager package by default. Ensure your system is up-to-date before proceeding with any configurations.
