Melindungi User Hotspot Mikrotik dari Virus

Pertama siapkan sebungkus rokok sampoerna, secangkir kopi dan silahkan duduk yang enak dengan santai. Untuk melindungi jaringan pelanggan/user, kita harus memeriksa semua lalu lintas yang melewati router dan blok yang tidak diinginkan. Untuk lalu lintas udp icmp, tcp, kita akan menciptakan rantai, di mana semua paket yang tidak diinginkan akan dijatuhkan. Untuk awal, kita bisa copy dan paste perintah berikut ke RouterOS konsol terminal:

/ip firewall filter
add chain=forward connection-state=established comment="allow established connections"  
add chain=forward connection-state=related comment="allow related connections"
add chain=forward connection-state=invalid action=drop comment="drop invalid connections" 

 lalu masukkan perintah ini :
/ip firewall filter

add chain=forward action=jump jump-target=virus comment="jump to the virus chain"

maka akan tampak pada filter rule seperti gambar di bawah ini. 

buka konsol terminal pada winbox mikrotik 

setelah itu kita masukkan perintah untuk memblock port-port virus

/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"

setelah selesai maka akan nampak seperti ini :
