Setting Firewall sederhana pada Mikrotik...
Sorry ni sebelumnya mau minta maaf nie kalau aku uda lancang membahas tentang mikrotik maupun tentang biikin Router atau Firewallnya.Dan yang pasti aku cuma mo berbagi ilmu nie kepada Blogger semua.Siapa tahu kita bisa share ilmu nie.Terus terang aku nie masih newbie tentang itu semua.dan aku juga uda pernah cobain tuh ilmu ternyata berhasil walaupun memakan waktu yg agak lama gitu..... Ya uda kita mulai aja ya...
1.Tentunya siapkan sebuah PC yg sudah terinstal Mikrotik.
2.Sediakan minuman dan snack ringan yg bisa bikin kita rileks saat stress.iu dikarenakab pada saat mengeset firewall pasti banyak hambatan untuk para newbie.Untuk minuman Recommended nya sich enakan BIR ya.hehehehe....ga jadi dunk settingnya tapi malah mabuk. ^_^
3.Siapkan mental diri anda
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 = 202.67.33.7Untuk membuat address-list dapat menggunakan contoh skrip seperti berikut ini tinggal disesuaikan dengan konfigurasi jaringan Anda.

Walhasil dari setting diatas adalah :
router mikrotik hanya dapat diakses FTP, SSH, Web dan Winbox dari IP yang didefinisikan dalam address-list “ournetwork” sehingga tidak bisa diakses dari sembarang tempat. Port-port yang sering dimanfaatkan virus di blok sehingga traffic virus tidak dapat dilewatkan, tetapi perlu diperhatikan jika ada user yang kesulitan mengakses service tertentu harus dicek pada chain=”virus” apakah port yang dibutuhkan user tersebut terblok oleh firewall. Packet ping dibatasi untuk menghindari excess ping.
Sekian dulu pembahasan dari saya.Jika da yang salah mohon koreksinya.Maklum masih Newbie ni.
Bahan dari diatas adalah Kompilasi dari hasil Googling saya....^_^

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