Scipt Mikrotik : Blokir IP Address Yang Mencoba Login di Router Mikrotik Secara Brute Force

      Comentario  
berikut cara block IP yang mencoba login ke router mikrotik (secara brute force) kita secara otomatis.




BUKA TERMINAL MIKROTIK 

 / ip firewall filter
add chain=input in-interface=ether1 protocol=tcp dst-port=21-23 src-address-list=ftp_blacklist action=drop

 add chain=output action=accept protocol=tcp content="530 Login incorrect" dst-limit=1/1m,4,dst-address/1m

 add chain=output action=add-dst-to-address-list protocol=tcp content="530 Login incorrect" address-list=blacklist address-list-timeout=48h

note : maksud dari langkah diatas adalah saat seseorang mencoba login ke router mikrotik kita (brute force) dalam minimal sebanyak empat kali dalam satu menit ( dst-limit=1/1m,4) 

 maka akses login yang ke lima router akan memasukkan Ip tersebut ke dalam daftar blacklist address dan membannednya selama 48 Jam (address-list=blacklist address-list-timeout=48h).

Sejak China Banned IP DNS Google, apa alternatifnya?

Pertanyaan diatas pernah dijawab James Smith dalam salah satu forum QUORA.
DNS yang direcomendasikan yaitu menggunakan openDNS.



OpenDNS : 
208.67.222.222 
208.67.220.220
Google DNS : 
8.8.8.8
8.8.4.4
CloudFlare DNS : 
1.1.1.1
1.0.0.1

 note : Google DNS is fast and great, but it’s not a reliable choice in China
