add chain=input in-interface=public protocol=tcp dst-port=22 src-address-list=ftp_blacklist action=drop
# accept 10 incorrect logins per minute
/ ip firewall filter
add chain=output action=accept protocol=tcp content="530 Login incorrect" dst-limit=1/1m,9,dst-address/1m
#add to blacklist
add chain=output action=add-dst-to-address-list protocol=tcp content="530 Login incorrect" address-list=blacklist address-list-timeout=3h
=============================================================
kalo kode diatas ini jika dalam 1 menit berusaha 10 kali login (lht script baris kedua, dst-limit=1/1m,9 di login nya yg kesepuluh masuk daftar hitam dan diban selama 3jam, address-list=blacklist address-list-timeout=3h).
kalo mo dibuat range juga bisa portnya tinggal dikasi dst-port=21-23 (utk ftp,ssh,telnet)
