+# VPN
+
+A VPN is a virtual private network.
+It uses a secure connection between a computer and a network or two networks.
+It can be used to display another IP address but does not make tracking or
+fingerprinting of the device impossible.
+VPNs feature a server and a client side.
+
+## OpenVPN
+
+[OpenVPN](https://openvpn.net) is a free software to create a VPN via an
+encrypted TLS connection.
+
+### Set up
+
+In the following sections the different set ups of OpenVPN usages are described.
+
+#### Server
+
+The software can be set up via [Docker](/wiki/docker.md) with the
+[kylemanna image](./docker-images/kylemanna_-_openvpn.md).
+Additionally to this a client is needed on the system that need access to the
+server software.
+
+#### Client
+
+OpenVPN clients can be found for many devices.
+For Android for example there is
+[OpenVPN for Android in the F-Droid store](https://f-droid.org/de/packages/de.blinkt.openvpn/).
+For most linux distributions there is a package called `openvpn`.
+
+#### Proxy
+
+For OpenVPN a proxy acts as an imntermediary between the system communicating
+with the proxy and the OpenVPN server.
+A proxy can be set up via [Docker](/wiki/docker.md) with the
+[jonohill image](./docker-images/jonohill_-_docker-openvpn-proxy.md).
