Neviem či to pomôže a či je to ono čo si chcel, ale ja mam na MK tieto pravidla:
/ip firewall filter
add action=jump chain=input comment="Jump to: ICMP" in-interface="ether1-Hlavna brana(PBI)" jump-target=icmp protocol=icmp
add action=jump chain=forward jump-target=icmp protocol=icmp
add action=jump chain=output jump-target=icmp out-interface="ether1-Hlavna brana(PBI)" protocol=icmp
add chain=icmp comment="Limits pings ICMP" limit=50/5s,2
add chain=icmp comment="Accept ICMP - INPUT" log-prefix=ICMP
add action=log chain=icmp comment="Log: ICMP" disabled=yes log=yes log-prefix=ICMP
