Tips Konfigurasi Firewall Mikrotik

Sudah banyak tips trik konfigurasi firewall mikrotik di internet.saya hanya ingin menambahkan tips konfigurasi yang saya modifikasi sendiri.
script nya di copas aja di terminal, firewall berikut untuk block port" yang sering di pake virus, dan juga akses ke mikrotik di batasi hanya untuk ip-ip di address-list aour network

Kita buat dulu address-list dgn nama ournetwork, diisi IP yang di ijinkan untuk akses mikrotik anda.

---

/ ip firewall address-list
add list=ournetwork address=x.x.x.x/x disabled=no
add list=ournetwork address=192.168.0.0/24 disabled=no
/

---

Trus kita masukin script firewall nya:

---

/ ip firewall filter
