+# Gluetun
+
+[Gluetun](https://github.com/qdm12/gluetun) is a free and open-source Docker-based VPN client.
+It supports multiple VPN providers and protocols including [WireGuard](/wiki/wireguard.md) and
+[OpenVPN](/wiki/openvpn.md).
+
+## Setup
+
+Gluetun can be set up via [Docker](/wiki/docker.md) with the
+[qmcgaw image](/wiki/docker/qmcgaw_-_gluetun.md).
+
+## Usage
+
+This section addresses the usage of Gluetun.
+
+### Routing Traffic of Firefox' Containers
+
+Gluetun routes the network traffic of Docker containers through a VPN tunnel.
+It can be used as a gateway for other containers or in combination with [Firefox'](/wiki/firefox.md)
+Multi-Account Containers to access selected websites through a VPN without routing all system
+traffic through the tunnel.

+Usually this is `0.0.0.0` and makes the VNC server on all network interfaces.

+## VNC over SSH
+
+Instead of exposing a VNC server to the network it can be accessed through an
+[SSH tunnel](/wiki/linux/openssh.md#port-tunneling).
+
+It is recommended to bind the VNC server only to `127.0.0.1` (for example as explained in the
+[wayvnc article](/wiki/linux/wayvnc.md#binding-to-an-ip-address)).
+This ensures that the VNC server is only accessible through the SSH tunnel.
+
+Assuming now the VNC server is bound to `127.0.0.1:5900`, a tunnel can be created from the local
+machine to the remote host, making the VNC server available on a local port such as
+`localhost:5901`.
+
+This setup keeps the VNC server inaccessible from the network while all VNC traffic is encrypted by
+SSH.
+It may also be useful to avoid program-specific VNC authentication, which may limit the
+compatibility of [VNC clients](#vnc-clients).
