I have two computers in lan network.
I want to block ping requests from one to another (firewall testing).
There's no other filter rules.
I tried to add this
/ip firewall filter add action=drop chain=forward protocol=icmp
and this
/ip firewall filter add action=drop chain=input protocol=icmp
and even this
/ip firewall filter add action=drop chain=output protocol=icmp
but still I can ping one pc from another.
What am I doing wrong? Thanks for any help.
