Setting Up an OpenVPN Server on a Raspberry Pi 4B

This is a note when setting up an Open VPN server on Raspberry Pi 4B. I tried a few methods, so I will briefly record each one.

Method 1: pivpn

I think this is the easiest and most reliable method. You can set it up just by following the instructions after executing the command below.

curl -L https://install.pivpn.io | bash

• pivpn/pivpn - GitHub

Method 2: Docker

I wanted to implement it this way if it worked properly, but it didn't support arm64, or the container kept restarting and didn't work well.

The images I tried are as follows:

• mje-nz/rpi-docker-openvpn
  • Fork of kylemanna/openvpn that supports rpi
  • Fails and enters a restart loop after startup
• evolvedm/openvpn-rpi
  • rpi-supported openvpn server
  • Fails and enters a restart loop after startup
• linuxserver/openvpn-as
  • Only supports the x86_64 architecture
• kylemanna/openvpn
  • Only supports the x86_64 architecture

It might work with the first two if I can use them properly.

Method 3: Steadily working while referring to the Arch wiki

It seems like you can manage by following the URL below.

• Easy-RSA
• OpenVPN

If you want to understand the mechanism, it might be worth giving it a try, but if you just want to set up a VPN server on a Raspberry Pi, I recommend pivpn.

I also tried creating an Easy RSA client file, but I stopped midway because I thought there would be a better way.
