Pengamankan router mikrotik dari traffic virus dan excess ping dapat digunakan skrip firewall berikut

Pertama buat address-list "ournetwork" yang berisi alamat IP radio, IP LAN dan IP WAN atau IP lainnya yang dapat dipercaya

Dalam contoh berikut alamat

IP radio adalah = 10.0.0.0/16,

IP LAN = 192.168.2.0/24 dan

IP WAN = 203.89.24.0/21 dan

IP lainnya yang dapat dipercaya = 202.67.33.7

Untuk membuat address-list dapat menggunakan contoh skrip seperti berikut ini tinggal disesuaikan dengan konfigurasi jaringan Anda.

Buat skrtip berikut menggunakan notepad kemudian copy-paste ke console mikrotik

/ ip firewall address-list
add list=ournetwork address=203.89.24.0/21 comment="Datautama Network" disabled=no
add list=ournetwork address=10.0.0.0/16 comment="IP Radio" disabled=no
add list=ournetwork address=192.168.2.0/24 comment="LAN Network" disabled=no

Selanjutnya copy-paste skrip berikut pada console mikrotik
