Raspberry Pi
Run a VPN server on your Raspberry Pi

VPN Server on your Raspberry Pi

Because, why not. When developing technology, what use is it when you can't run it on the smallest and cheapest of devices? Why do we always need the latest and greatest to run anything? If you write software and it does NOT run on a Raspberry Pi with ease, you are doing something wrong ;-)

I tested this last on a Raspberry Pi 3B+ and Fedora 33 (aarch64) on 2021-01-21 and all works fine. Packages for Fedora 33 and 34 are available.

Raspberry Pi 4

If you are trying to install on the Raspberry Pi 4 make sure you use the Fedora 35 beta (or later) image for aarch64, at the time of writing that is Fedora-Minimal-35_Beta-1.2.aarch64.raw.xz.

You can find it here.

When writing the image using arm-image-installer you use rpi4 as --target parameter.

Getting Started

So, the first step is to find your Raspberry Pi 3B+ or 4 and get ready! Most of the steps here are not specific to the VPN server, but just getting Fedora up and running, and up to date!

Download the latest "Fedora Minimal" image from here make sure you look under the "ARM aarch64 Architecture" section. The download will be a raw.xz file.

Full instructions for installing Fedora on the Pi can be found here. I'll repeat the important steps below.

I used this command to create the SD card for the Pi on my laptop running Fedora.

To write to SD-card, for USB disk you would use something like --media=/dev/sdb:

$ sudo arm-image-installer --image=Fedora-Minimal-34-1.2.aarch64.raw.xz --resizefs --target=rpi3 --media=/dev/mmcblk0

Make sure you specify the --resizefs option to "grow" the file system to fill your SD card/USB disk.

The Wiki linked to above has instructions for other platforms as well.

You need to boot this image, configure the network, install all software updates and enable (remote) SSH login if you prefer. It is a little bit easier and you don't need a keyboard/mouse attached to your Pi anymore. If you want to use WiFi, it DOES work out of the box with the Raspberry Pi 3B+ on at least Fedora >= 32, but you need to configure it through the CLI as mentioned on the Wiki. The "installer" does not support it. First walk through the setup "wizard". Make sure you either create an account with "Administrator" permissions, or set a root password.

To configure WiFi if you don't have an ethernet connection:

$ sudo nmcli device wifi connect "Your SSID" --ask

After connecting to the network, install all updates:

$ sudo dnf -y --refresh update

Set the hostname to the name you want to give your VPN server:

$ sudo hostnamectl set-hostname

This concludes setting up Fedora on your Pi. Make sure everything works as expected and reboot before attempting to install the VPN software. Make sure your network connection is still working before continuing.

Installing the VPN server

This is the easy part. Follow the instructions here, make sure you enable the development repository when you call


After you are done with this, all should be fine as if you performed the installation on any other Fedora server.


After installation, you probably want to switch away from using RSA for your VPN client and certificates for performance reasons, look here on how do that, and here for why, take note of the table comparing the key generation/signing times...
