Is this possible with bridges?

Hi all!

I’ve 4 mikrotiks working as AP, each one with a wireless card (AP) and a ethernet port on the same bridge. Those Mikrotiks are connected switch. On this switch I’ve a 4th mikrotik (main mikrotik) that is the router of this network.

I want to eliminate all the traffic between the mikrotiks that are in bridge and plugged on the same switch, I want that each mikrotik just see the “main mikrotik” that is the router of the customers that are connecteds on the wireless interfaces of my APs. I want this to drop the traffic between clients (something like the mikrotik make on the traffic of the clients that are connecteds on the wireless interface).

Is this possble? If yes, how can I solve this?

Thanks

My approach would be to use /ip firewall filter to accept connections from any machine on the LAN to the router, and from the router to any machine on the LAN, but in a following rule drop connections between any address on the LAN and any address on the LAN. Don’t know for sure that this would work, but it’s cheap to try.
