How to Setup a VPN on Raspberry Pi

How to turn your Raspberry Pi into a Home VPN Server using PiVPN

Building A Raspberry Pi VPN Part One: How And Why To Build A Server
Thanks for your tutorial, it is very well documented!! You need to perform this step for every client you set up. This screen confirms your current IP address for the Pi. Now, this screen above just tells us that the next one is going to show the default values for the security certificate info. Tue Apr 04

Remember to Update!

Press enter or whatever you want, but pay attention to these three fields: It should default to this. Enter PEM pass phrase Make it a password you will remember! OpenSSL stands for an open source implementation of Secure Socket Layer, a standard method of setting up a secure connection. You need to perform this step for every client you set up. Some argue this step is unnecessary, and that you could simply skip this line.

Otherwise, current versions could have difficulty parsing the keys you just generated. This is the central code that makes your VPN server tick, an exchange that lets two entities with no prior knowledge of one another share secret keys over a public server.

In fact, while I was making this tutorial, it only took 5 minutes with bit encryption. OpenVPN has a way to prevent this kind of attack from occurring before it even starts by generating a static pre-shared hash-based message authentication code HMAC key. The OpenVPN program is already running. But for now, this file is completely blank. Fill it in with this. By default, Raspbian does not forward Internet traffic. We need to edit another file to allow the Pi to forward Internet traffic through our new network.

To uncomment the line, remove the immediately in front of it. This is setting up the configuration so it knows to forward to IPv4. Raspbian has a firewall to protect your Raspberry Pi from unknown and unexpected Internet sources. We still want the firewall to protect us from most incoming and outgoing network traffic, but we need to poke an OpenVPN-shaped hole in the firewall.

Now we just need to inject it into the interfaces setup code so it runs on boot. Find the line that goes: Creating An Encrypted Client Side. Raspberry Pi Model B photo by Tors.

So next, we type: The screenshot below shows what that looks like: MUST be left blank. All this and more are configured out of the box by the pivpn installer. This is a detailed level of hardening you'll have a difficult time finding elsewhere. There are quite a few various scripts that in some way install openvpn for you. This project in particular began from the code by StarshipEngineer to help make installing OpenVPN on a raspberry pi as simple as it can be.

This is still the striving goal today see Why This Is Important just below. However, even with the solid foundation provided by StarshipEngineer, I had recently come across the Pi-Hole project and saw just how easy an installation can be! So I took the scripts from StarshipEngineer, the framework and functions from the pi-hole project, and merged them into what you now see as PiVPN.

I then added a ton of functionality, failsafe checks, hardened security, etc This should be bar none, the simplest and fastest way to setup an OpenVPN server on your raspberry pi that leaves you with an extremely secure configuration. I've made a few additions and tweaks as well to help make managing the OpenVPN server even easier after install. Everything can be managed by using a new 'pivpn' command on your system.

This includes adding new client certs, revoking them, and completely uninstalling the pivpn. There is a lot more that can be added and I hope the suggestions and improvements can be contributed by the community at large. There are a few driving factors that make this very important to me and I believe the community at large. In this post Snowden era where our privacy and security is infringed upon, not only by bad actors but potentially by those whom we thought should be protecting these very ideals, it is necessary for normal citizens to take matters into their own hands.

The trouble with this, many times, is that if you are not very technical you may not know how to begin. Allowing many to now have their sites on encrypted channels. To me, the next logical step here is also ensuring the pipe you are using is as secure as possible. This not only could include unknown networks at airports, Starbucks, generic public hot-spots; but also your ISP.

To that end I'd like to make sure these scripts also work on a Debian Jessie image from an Amazon free tier server. It is important that more and more people have access to protecting their traffic online. It's clear others won't hand you this protection. PiVPN tries to make it easier for you to grab. OpenVPN is undergoing a security audit. This means that at the end of the audit, this software we all rely on to help protect the security of our traffic will be in even better shape.

Here is an article announcing the audit. This way we gain the security fixes that will come post audit. At that time we will also be able to use the better EC elliptic curve ciphers in creating certificates which should be more secure and also less taxing on clients. The links below showcase some good write ups and tutorials that use PiVPN. Some other decent information may also be contained regarding VPNs and security in general.
