Firewall Mikrotik: Untuk Mengamankan Klien

Ngomongi Firewalll gak ada habisnya....
Gak bisa di perdebatkan mana yg baik / mana yang buruk, semua ada baik buruknya
Artinya yg rapet rentan terbelenggu dewe, yg longgar rentan rusak, yang pilih kasih rentan komplen, yg adil rentan masalah, gak di pasang yo kebangeten...bingung ra??

Intinya adalah: Boleh ote2 jika memang sudah terlatih dan memang asline wis kuwat.
Dan boleh rangkep2 misal'e: wis pakek celana juga pakek sarung juga pakek CD juga pakek kolor juga pakek rok bahkan juga pakek pembalut wanita...wakakakaka....

Kuuuwabeh itu semua hukum'e boleh, cuman...pas apa gak buat kita?
Nanti nek terlalu banyak rangkep'e terus bagaimana nek pas kebelet pipis bahkan ek'ok sing gak tertahan lagi?

Ujung-ujungnya semua yg terpakai dgn terpaksa akan ditanggalkan satu demi satu karena terlanjur pesing kena pipis bahkan bau kena ek'ok...apakah itu yg dinamakan bagus..???
Terserah penilaian anda...

Saya akan coba memberi contekan sekedar buat nahan virus alakadarnya, dan silahkan copas di MikroTik anda. Tp Do With Your Own Risk lho ya....

Ini script-nya :
