Good day!
How should I blocked the unwanted user who are connected to a network for not using Internet or other data transaction and didn’t affect the specific IP assigned.
/ip firewall filter
add chain=forward src-address=192.168.0.0/24 action=drop in-interface=!ether2
add chain=forward dst-address=192.168.0.0/24 action=drop in-interface=!ether2
/ip firewall filter
add chain=input src-address=192.168.0.30 action=accept in-interface=!ether2
add chain=input src-address=192.168.0.31 action=accept in-interface=!ether2
add chain=input src-address=192.168.0.42 action=accept in-interface=!ether2
add chain=input src-address=192.168.0.53 action=accept in-interface=!ether2
…etc
