In my dd-wrt firewall, I see the option:

filter multicast

I searched a lot about filtering multicast, but I could not find a comprehensive reply about this. Should I filter multicast on my LAN?

    It's going to depend on whether or not your LAN has services that use multicast. Firstly, do you know what multicast is? If we knew that, we could provide a more precise answer. – schroeder Jul 7 '16 at 19:11
