Understanding Raspberry Pi and VPN

You’re going deep into Raspberry Pi and VPN providers — both things that can fundamentally alter the way you connect online. Let's break it down to make it easier to get the hang of.

What is a Raspberry Pi?

Raspberry Pi is a mini-computer that fits in your hand and doesn’t cost much. It’s really flexible and does all sorts of work. Picture one computer that turns into whatever you want it to be.

You can make it your media center to watch all your shows, a game console to play old classics, or even a device for your home automation endeavors. When you’re choosing a Raspberry Pi, the Raspberry Pi 4 stands out. It has more power and features, which is why it’s ideal for complex tasks—such as setting up a VPN router.

What is a VPN?

Next, let's talk about VPNs, or Virtual Private Networks. Your online shield is a VPN. It also secures your internet connection by encrypting your data.

This scrambling prevents hackers from accessing your information, keeping it under wraps. VPNs accomplish this using various methods, such as OpenVPN or WireGuard. OpenVPN is a venerable, trusted option, but its code weighs in at a hefty 400,000 lines.

WireGuard, on the other hand, is the new kid on the block. It’s lighter and faster, requiring about 4,000 lines of code. Heads up, WireGuard stores IPs on the server, which isn’t ideal for everyone.

Why Use Raspberry Pi as a VPN Router?

Why would you want to use a Raspberry Pi as a VPN? It’s much cheaper than buying a commercial VPN router. You save money and still get all the benefits of a VPN.

You can plug multiple devices into your home network through it. That means your phone, laptop, and tablet can all enjoy secure browsing. You get the freedom to tweak settings and make it work just the way you like.

If you're worried that someone's going to end up subpoenaing your data or stealing your Raspberry Pi, then this isn't the project for you. Before you jump in, you’ve got a choice to make between OpenVPN and WireGuard.

OpenVPN uses port 1194 by default, while WireGuard uses port 51820. If you move around a lot with mobile devices, WireGuard is excellent, switching networks without dropping you.

Surfshark, a VPN service, is finally making some waves in testing and climbing the ranks. It still lags behind the likes of big-name rivals like ExpressVPN and NordVPN in speed.

Preparing for Setup

To configure your Raspberry Pi as a router with VPN capabilities, including a reliable VPN provider, you need to start with the proper hardware. Here's a quick checklist of what you’ll need.

• Raspberry Pi: It’s a small, affordable mini-computer. Almost no need for a case or even a mouse.

• Make sure it has enough room, at least 16GB, to store the OS and VPN files.

• This is to connect your Raspberry Pi to your network.

• It’s crucial to have a reliable one to keep your Raspberry Pi running smoothly.

• Check if your Raspberry Pi works with the VPN software you choose.

Gather Necessary Hardware

First, gather all your hardware together. Your Raspberry Pi will be the heart of this setup. Make sure your SD card or USB drive has at least 16GB of capacity. This way, you won't run out of space while using it.

Double-check that your Raspberry Pi model is compatible with the VPN software you're considering. Making sure it’s compatible is key to a successful install.

To set up your Raspberry Pi, connect it to a monitor, mouse, and keyboard. For a more “lean and mean” experience, you can SSH into it.

Obtain Essential Software

Next, let’s cover software. You'll also need the correct OS and VPN client to begin with. The suggested option here is the Raspberry Pi OS.

Download the newest version from the official site. This ensures that your system runs smoothly. Sometimes, when you install, you might have to edit the file to change the file type from .ovpn to .conf. This will ensure OpenVPN recognizes the file.

OpenVPN is a common option for VPN functionality on Raspberry Pi. Setting it up with text commands can be tricky. Fortunately, PiVPN provides an easier way to do this, which is significantly more user-friendly.

Before you move on to this section, we need to point out that if you haven’t yet, you need to go through our Wireless Access Point tutorial. This will set your Raspberry Pi up appropriately for this guide.

Dynamic DNS and Encryption

You might need a dynamic DNS (DDNS) service. Most Internet Service Providers (ISPs) assign dynamic IP addresses that change every 24 hours. DDNS solves this by providing a stable address for your Raspberry Pi router.

Finally, changing the level of encryption is an easy adjustment. Depending on your needs, you just change the export KEY_SIZE= line from 2048 to 1024.

Setting Up Raspberry Pi VPN Router

1. Install Raspberry Pi OS on SD Card

First up, get that Raspberry Pi OS onto your SD card. You'll need to use a nifty little tool called Etcher for this job. It's pretty straightforward: just download the Raspberry Pi OS image, open up Etcher, and flash it onto your 32GB high-speed MicroSD card.

Ensure your SD card is correctly formatted to prevent any issues down the line. Once complete, pop the SD card into the Raspberry Pi and power it on. You need a speedy card to keep everything running smoothly. With Gigabit internet, you can get up to 800 Mbps!

2. Configure Initial Raspberry Pi Settings

Next, we’ll take care of those first few settings. First, set your language, timezone, and network preferences. A solid, stable Ethernet connection is the name of the game here, as it keeps everything steady while you set things up.

Then, update those system packages so you’ve got the latest software. It's kind of like putting some fresh paint on your Raspberry Pi before getting down to the nitty gritty.

3. Install VPN Client Software

Now, let's get that VPN client installed. Depending on your preference, you can install either OpenVPN or WireGuard. You can do this by running a single command in the terminal.

After the installation process is completed, verify the software version to ensure proper installation. At this point, you may wish to uninstall IPv6 packages, as they can occasionally cause issues with VPN installations.

4. Choose Between OpenVPN and WireGuard

Comparing OpenVPN and WireGuard is a bit like dealing with an apples-to-oranges dichotomy. OpenVPN provides tried and true security protocols you can trust.

On the other hand, WireGuard is known for its speed and efficiency, requiring fewer resources. If you're looking to overclock your Pi 4, go with WireGuard. It handles top speeds easily, making it a better choice.

It can be overclocked up to 2.0GHz with the right heatsink and fan.

5. Import VPN Configuration Files

Let’s get on to importing those VPN configuration files. For OpenVPN, you'll need to download the .ovpn files. Save these files in the appropriate directory, so you’ll know where to find them.

Don’t forget to change the file type from .ovpn to .conf so OpenVPN can load them properly. Check the integrity of these files before you proceed to protect yourself from unpleasant surprises.

6. Adjust Configuration Files

Time to edit those configuration files. You can also edit the .ovpn files to add DNS servers and methods of authentication. Just double-check that the paths to those authentication files are exact.

Save your edits, and you’re good to go. This step prevents your VPN router’s network from conflicting with your home network, which is likely configured to 192.168.1.x.

7. Automate VPN Connection at Startup

Automate your VPN connection. Use system or cron jobs so your VPN will connect automatically when your Raspberry Pi boots. A simple script running the OpenVPN command with the right config file should do it.

Try this setup first to make sure your VPN connects without you having to do a thing.

8. Enable Network Forwarding and IPtables

Get that network forwarding and IPtables going. Execute commands to enable IP forwarding, making sure traffic is routed correctly.

Iptables rules will also help us control what traffic can come in; we will allow for VPN traffic but block any other connections. Keep a close eye on the Raspberry Pi’s temperature.

While 80% of users report no issues, staying vigilant can help prevent overheating.
