 By default the Jitsi Meet instance does not work with a client in LAN (Local Area Network), even if others are connected from WAN. There are no video and audio. In the case of WAN to WAN everything is ok.
 
-The reason is the Jitsi VideoBridge git to LAN client the IP address of the docker image instead of the host. The [documentation](https://github.com/jitsi/docker-jitsi-meet#running-behind-nat-or-on-a-lan-environment) of Jitsi in docker suggest to add `DOCKER_HOST_ADDRESS` in enviornment variable to make it work.
