Drop Port Scanners

Olá pessoal

Quero bloquear Port Scanner no Mikrotik, pesquisando achei as linhas abaixo:

/ip firewall filter

add chain=input protocol=tcp psd=21,3s,3,1 action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="Port scanners to list " disabled=no
add chain=input protocol=tcp tcp-flags=fin,!syn,!rst,!psh,!ack,!urg action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="NMAP FIN Stealth scan"
add chain=input protocol=tcp tcp-flags=fin,syn action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="SYN/FIN scan"
add chain=input protocol=tcp tcp-flags=syn,rst action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="SYN/RST scan"
add chain=input protocol=tcp tcp-flags=fin,psh,urg,!syn,!rst,!ack action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="FIN/PSH/URG scan"
add chain=input protocol=tcp tcp-flags=fin,syn,rst,psh,ack,urg action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="ALL/ALL scan"
add chain=input protocol=tcp tcp-flags=!fin,!syn,!rst,!psh,!ack,!urg action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="NMAP NULL scan"
add chain=input src-address-list="port scanners" action=drop comment="dropping port scanners" disabled=no

Testei e esta deixando passar.

Alguém tem uma regra que realmente barre qualquer tentativa por Ports Scanners ?

as minhas são:

/ip firewall filter

add chain=input src-address-list=”portscanners” action=drop comment="--------------- Bloqueia Scanner de Portas -------------" disabled=no

add chain=input protocol=tcp tcp-flags=fin,!syn,!rst,!psh,!ack,!urg action=add-src-to-address-list address-list=”portscanners” address-list-timeout=2w

add chain=input protocol=tcp psd=21,3s,3,1 action=add-src-to-address-list address-list=”portscanners” address-list-timeout=2w disabled=no

add chain=input protocol=tcp tcp-flags=fin,syn action=add-src-to-address-list address-list=”portscanners” address-list-timeout=2w

add chain=input protocol=tcp tcp-flags=syn,rst action=add-src-to-address-list address-list=”portscanners” address-list-timeout=2w

add chain=input protocol=tcp tcp-flags=fin,psh,urg,!syn,!rst,!ack action=add-src-to-address-list address-list=”portscanners” address-list-timeout=2w

add chain=input protocol=tcp tcp-flags=fin,syn,rst,psh,ack,urg action=add-src-to-address-list address-list=”portscanners” address-list-timeout=2w

add chain=input protocol=tcp tcp-flags=!fin,!syn,!rst,!psh,!ack,!urg action=add-src-to-address-list address-list=”portscanners” address-list-timeout=2w

Funcina perfeita..
