Access Your Raspberry Pi Remotely: Solutions & Secure Methods

Can you truly harness the power of your Raspberry Pi from anywhere in the world? The answer is a resounding yes, with the right tools and techniques, you can effortlessly access and control your Raspberry Pi, unlocking a world of remote possibilities.

The quest to remotely access a Raspberry Pi often begins with a frustrating roadblock: the network configuration. Many find themselves behind a VPN, which, while providing security, can inadvertently lock them out. Imagine having a Raspberry Pi dedicated to home automation, a security camera feed, or even just your personal files, but being unable to reach it when you're away. The solution lies in understanding the various methods available, each with its own set of advantages and considerations. Tailscale, for example, presents a simple solution for those seeking uncomplicated and secure remote access to their Raspberry Pi or any other device, leveraging WireGuard for fast and encrypted connections while streamlining VPN setup complexities.

There are several methods to gain access, each with its own set of merits. Exposing SSH or VNC, using a VPN, or employing external services like RealVNC's cloud VNC viewer are all viable strategies. Similarly, Raspberry Pi Connect offers a free screen-sharing and remote shell service. One can also create a Raspberry Pi VPN gateway by first connecting the Raspberry Pi to a VPN provider, and then configuring it as an access point. This directs incoming traffic through the VPN service, functioning as a gateway. The ability to access a Raspberry Pi remotely opens up a wealth of opportunities. From monitoring home automation systems and accessing files to remotely managing projects, the possibilities are endless. The key lies in selecting the right tools and understanding how they interact to establish a secure and reliable connection.

For those who have found themselves in this predicament, the good news is that numerous solutions exist. One popular approach involves using a second Raspberry Pi for remote monitoring. In the meantime, one can access their raspberry pi locally using the network folder on their laptop. Installing WireGuard on the Pi and accessing Docker containers remotely using a WireGuard VPN and the proper port via a browser are another efficient options.

The following table provides a summary of the different methods and tools for remote access to a Raspberry Pi:

The choice depends on your technical comfort level and the specific needs of your project. For instance, if you prioritize ease of setup and don't require full desktop access, Tailscale or Raspberry Pi Connect might be ideal. For those comfortable with the command line and prioritizing security, SSH is a strong option. And for comprehensive access to the graphical interface, VNC remains a popular choice.

The process of setting up a remote VPN gateway can be straightforward. You can achieve this by connecting your Raspberry Pi to a VPN provider and configuring it as an access point. This setup allows the Pi to route all incoming traffic through the VPN service, essentially acting as a gateway. As an example of this the content mentioned: "Today, we're going to show you how straightforward it is to set up a remote VPN gateway on any LAN using just a Raspberry Pi 4 and TorGuard's dedicated WireGuard service."

The basic steps involved in setting up a Raspberry Pi as a VPN server typically include installing a VPN client on the Raspberry Pi, configuring it to connect to a VPN provider, and then setting up port forwarding or a similar mechanism to allow external devices to connect to the Raspberry Pi through the VPN.

Consider the scenario: you have a Raspberry Pi that's always on and connected to a VPN, yet you're unable to access it remotely. To solve this, you could explore options such as using a second Raspberry Pi or leveraging tools like Tailscale or Ngrok. This setup then enables you to securely access your Raspberry Pi projects from anywhere. The key benefits of using a Raspberry Pi as a VPN server include secure remote access to your home network, access to files, IoT devices, cameras, and other network resources securely. It also allows access to your Pis terminal remotely within a local network.

For a reliable and high-speed connection, a Raspberry Pi 4 with a wired Ethernet connection is recommended. You'll also need a power supply and a microSD card with at least 8GB of storage. Your phone can be any modern Android or iOS device with Wi-Fi connectivity, providing flexibility for remote access.

The hardware requirements are quite modest, which makes setting up a remote workstation accessible to anyone. However, to control your Raspberry Pi from your phone, you will need a Raspberry Pi board (any model from Pi 3 or newer, though the Raspberry Pi 4 capabilities offer the best experience), a power supply, and a microSD card with at least 8GB storage. And in order to ensure your raspberry pi is connected via wired ethernet, you should disable the Wi-Fi connection.

To set up a remote desktop you have to follow these guidelines:

• Choose a Remote Access Method: Select the method that best fits your needs (SSH, VNC, Tailscale, etc.)
• Configure Network Settings: Ensure your Raspberry Pi has a static IP address or uses a dynamic DNS service.
• Install the Necessary Software: Install the software required for your chosen method (e.g., an SSH server, a VNC server).
• Configure Port Forwarding (If Applicable): If using SSH or VNC, configure port forwarding on your router to allow external access.
• Test the Connection: Test the remote access from another network to ensure it works correctly.

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 username@your_raspberry_pi_ip_address:/home/username/

This tutorial provides a walkthrough of installing and configuring Tailscale on your Raspberry Pi. Using commercial VPN services is an option. However, hosting your own gives you complete control and ensures that your data isn't being logged by a third party. With a Raspberry Pi, you can generally use it to access a remote network from anywhere in the world, such as accessing your security camera or home automation web page from your smartphone while traveling.
