+# coturn - coturn
+
+This is a [Docker](/wiki/docker.md) container for a TURN/STUN server.
+A server like this can be used in a [Matrix](../matrix.md) server configuration.
+The official container and documentation was made by
+[coturn](https://github.com/coturn/coturn).
+This docker-rebuild is made up by a `docker-compose.yml` file.
+
+## Set-up
+
+Create the files `rebuild.sh`, `data/matrix/coturn/turnserver.conf` and `docker-compose.yml` at the
+same place.
+Change the settings according to your needs and run `./rebuild.sh` afterwards.
+For the `data/matrix/coturn/turnserver.conf` file change the values for `static-auth-secret`,
+`realm`, `cli-password` and `external-ip`.
+For the passwords [OpenSSL](/wiki/linux/openssl.md#password-generator) can be used to create a
+sufficiently random password.
+The value of `external-ip` consists of the local IP (left side) and the public IP (right side).
+To get the local IP the command `ip route get 1` can be used.
+For the public IP the command `curl api.ipify.org` can be used.
+
+
+## Ports
+
+Set the following ports in the `ports:` section.
+
+| Container Port | Recommended outside port | Protocol | Description |
+| -------------- | ------------------------ | -------- | ----------- |
+| `3478`         | `3478`                   | TCP/UDP  | TURN/STUN   |
