Menahan serangan Floding Attack pada Mikrotik

Konfigurasi dibawah ini dapat memblokir beberapa Trojan, Virus, Backdoor
yang telah dikenali sebelumnya baik Nomor Port yang dipakai serta Protokolnya.
Juga telah di konfigurasikan untuk menahan Flooding dari Jaringan Publik dan
jaringan Lokal. Serta pemberian rule untuk Access control agar, Rentang
jaringan tertentu saja yang bisa melakukan Remote atau mengakses service
tertentu terhadap Mesin Mikrotik kita.
