UDP Broadcasts to a docker

I have setup node-red as a docker and all with working good apart from the UDP packets I am trying to capture are not visible.  The same flow works perfectly on a RPI running Node-Red so it looks like for what ever reason the UPD broadcasts are not getting forwarded to the docker, is there anything special I have to do to enable this?  I did try adding the port 22600 but still no luck.  I do know the  broadcasts are always to 224.192.32.19 & port 22600.

Any help would be appriciated.

    Running the container with host networking works. Not sure if it works if you set an IP for the container on a custom bridge.

     

    If I'm thinking about it, I read UDP as multicast UDP. If it's just normal UDP, you may the correct port and set it to udp. The default is TCP.
