In FreeBSD a lot of people use the concept of jails and they are not necessarily setup to be able to use layer 2 broadcast packets or anything a like. Most jail setups only allow for layer 3 communication with LAN clients through routing of packets. I'm wondering where does Emby use layer 2 for? Device discovery? Does it use layer 2 for anything around google home integration? Anything else I might be misisng?
