+Where `DOCKER_IP` is the public IP address where Docker services can be reached. This will be used by Janus to send back the right IP to Web clients (ICE candidates) so that they can communicate with Janus correctly.

 That's it!
 
 Details:
 
 To make this even easier, copy `docker-compose.yml` [from this repo](https://github.com/linagora/docker-janus-gateway/blob/master/docker-compose.yml). Then you'll only need to:
 
 ```shell
-$ docker-compose up
+$ DOCKER_IP=<YOUR DOCKER IP> docker-compose up
 ```
 
 Where ports:
   - **80**: expose janus documentation and admin/monitoring website
   - **7088**: expose Admin/monitor server
   - **8088**: expose Janus server
   - **8188**: expose Websocket server
+  - **10000-10200/udp**: Used during session establishment
