Docker + Wake on LAN from CMS issue

Dear community,

I am having some trouble getting Wake on LAN to work with the docker container. I am fairly new to docker but I think it has to do with the bridged network connection the containers are using.
My problem is: I can wake up xibo player clients from the server hosting the docker containers, but the Wake on LAN feature from the CMS is not working.

E.g. i want to wake up in a class b network, so I use as the broadcast in CMS (which works from the server) but it’s not waking up.

Can you help me with some clues how to get this working?
