Block ping hosts

Hi

Does anybody know?, How I can configure my Mikrotik router to block pings between hosts in the same subnet?

The scenario is I have a Switch and all hosts are connected to it and the switch connect it to MKT Router.

Thanks

simply, YOU CAN NOT DO!

substitute the switch with one routerboard, and you can do that on routerboard firewall.

Wouldn’t it be better to place a firewall on the host, then block ICMP at the host level?
