Saya mempunyai beberapa konfigurasi firewall chain mikrotik untuk menangkal masuknya virus dan serangan hacker dari dunia gaib :D yang akan saya share pada kalian. Okey, perhatikan baik-baik langkah-langkah dibawah
Cara Setting Firewall Mikrotik Untuk Block Virus dan Serangan Hacker
Langkah pertama buka terminal mikrotik kalian, kemudian masukan kode perintah dibawah
/ ip firewall filter add chain=virus protocol=tcp dst-port=135-139 action=drop comment="Drop Blaster Worm" add chain=virus protocol=udp dst-port=135-139 action=drop comment="Drop Messenger Worm" add chain=virus protocol=tcp dst-port=445 action=drop comment="Drop Blaster Worm" add chain=virus protocol=udp dst-port=445 action=drop comment="Drop Blaster Worm" add chain=virus protocol=tcp dst-port=593 action=drop comment="________" add chain=virus protocol=tcp dst-port=1024-1030 action=drop comment="________" add chain=virus protocol=tcp dst-port=1080 action=drop comment="Drop MyDoom" add chain=virus protocol=tcp dst-port=1214 action=drop comment="________" add chain=virus protocol=tcp dst-port=1363 action=drop comment="ndm requester" add chain=virus protocol=tcp dst-port=1364 action=drop comment="ndm server" add chain=virus protocol=tcp dst-port=1368 action=drop comment="screen cast" add chain=virus protocol=tcp dst-port=1373 action=drop comment="hromgrafx" add chain=virus protocol=tcp dst-port=1377 action=drop comment="cichlid" add chain=virus protocol=tcp dst-port=1433-1434 action=drop comment="Worm" add chain=virus protocol=tcp dst-port=2745 action=drop comment="Bagle Virus" add chain=virus protocol=tcp dst-port=2283 action=drop comment="Drop Dumaru.Y" add chain=virus protocol=tcp dst-port=2535 action=drop comment="Drop Beagle" add chain=virus protocol=tcp dst-port=2745 action=drop comment="Drop Beagle.C-K" add chain=virus protocol=tcp dst-port=3127-3128 action=drop comment="Drop MyDoom" add chain=virus protocol=tcp dst-port=3410 action=drop comment="Drop Backdoor OptixPro" add chain=virus protocol=tcp dst-port=4444 action=drop comment="Worm" add chain=virus protocol=udp dst-port=4444 action=drop comment="Worm" add chain=virus protocol=tcp dst-port=5554 action=drop comment="Drop Sasser" add chain=virus protocol=tcp dst-port=8866 action=drop comment="Drop Beagle.B" add chain=virus protocol=tcp dst-port=9898 action=drop comment="Drop Dabber.A-B" add chain=virus protocol=tcp dst-port=10000 action=drop comment="Drop Dumaru.Y" add chain=virus protocol=tcp dst-port=10080 action=drop comment="Drop MyDoom.B" add chain=virus protocol=tcp dst-port=12345 action=drop comment="Drop NetBus" add chain=virus protocol=tcp dst-port=17300 action=drop comment="Drop Kuang2" add chain=virus protocol=tcp dst-port=27374 action=drop comment="Drop SubSeven" add chain=virus protocol=tcp dst-port=65506 action=drop comment="Drop PhatBot,Agobot, Gaobot" add chain=virus protocol=udp dst-port=12667 action=drop comment="Trinoo" disabled=no add chain=virus protocol=udp dst-port=27665 action=drop comment="Trinoo" disabled=no add chain=virus protocol=udp dst-port=31335 action=drop comment="Trinoo" disabled=no add chain=virus protocol=udp dst-port=27444 action=drop comment="Trinoo" disabled=no add chain=virus protocol=udp dst-port=34555 action=drop comment="Trinoo" disabled=no add chain=virus protocol=udp dst-port=35555 action=drop comment="Trinoo" disabled=no add chain=virus protocol=tcp dst-port=27444 action=drop comment="Trinoo" disabled=no add chain=virus protocol=tcp dst-port=27665 action=drop comment="Trinoo" disabled=no add chain=virus protocol=tcp dst-port=31335 action=drop comment="Trinoo" disabled=no add chain=virus protocol=tcp dst-port=31846 action=drop comment="Trinoo" disabled=no add chain=virus protocol=tcp dst-port=34555 action=drop comment="Trinoo" disabled=no add chain=virus protocol=tcp dst-port=35555 action=drop comment="Trinoo" disabled=no add action=drop chain=forward comment=";;Block W32.Kido -

Selesai, sekarang jaringan kita sudah cukup aman menghadapi virus dan serangan hacker. Saya tidak berani menjamin 100% aman karena kita semua faham diatas langit masih ada langit ;) - semoga membantu
