Block ports 67 and 68, in TCP and UDP.

And do not see computers between them?

Then block port 137 to 139 TCP and UDP (NetBIOS), if you want to block traffic between client APs then disable the “default forward” option in your wireless interface.

What caind of traffic do you want to block? This rule bloks shared folders (NetBIOS)

My mistake, Netbios port is 135-139. Try blocking ports 135 to 139. In chains INPUT and FORWARD and UDP - TCP protocols.
