simple-openvpn-server VS openvpn-pihole

Another option can be openvpn, https://github.com/theonemule/simple-openvpn-server.

its amazing and you don't need to be a expert to use it.

Say I want to setup a VPN between 5 computers. I would need one server that "hosts" the VPN and configuration files for each of the 5 computers. The purpose of the VPN is purely to allow the 5 computers to securely communicate. It does not provide routing to the internet via the VPN. I could probably use something like https://github.com/theonemule/simple-openvpn-server on the cheapest VPS I could find and it would have no problems.

From a technical perspective just go with whichever suits you better - if you have the tech skills to set it up yourself that's probably cheaper. If not, or you don't have time, go with a provider. For a very simple DIY VPN, https://github.com/theonemule/simple-openvpn-server is pretty easy to setup!

Another VPN option is https://github.com/theonemule/simple-openvpn-server - It's open source, all you need is a VPS then run the install script. Once it's finished, you can create clients and download the openvpn config file for them from the web interface.

I setup a openvpn-pihole docker combo container onto my cloud VPS, which has a public static IP. Pihole must run behind VPN and I am only interested in dns queries, in other terms I don't want my internet traffic get routed by the VPN server. I read everywhere that I should comment out this line in the server.conf file (and I did do):

if you know how to create and maintain an open vpn server of course the self-hosted solution is better, any other vpn provider can use your data beyond your knowing, big problem is that they host servers all over the world so in its "vpn server" they have deferent rules from the country that they are located, so if we speak about personal integrity you can host your service in Europe where the gdpr is very restricted about personal data. If you are open to suggestions about the server provider I recommend you hertzner. For me personal for everyday use I use my self-hosted open-vpn/ pihole(inside the vpn with docker) and for multimedia consumption, I use proton vpn to have access to content from all over the world.
