action=drop
* /ip firewall filter add chain=forward dst-port=135-139 protocol=udp
action=drop
* /ip firewall filter add chain=forward dst-port=445 protocol=tcp
action=drop
* /ip firewall filter add chain=forward dst-port=445 protocol=udp
action=drop
* /ip firewall filter add chain=forward dst-port=593 protocol=tcp
action=drop
* /ip firewall filter add chain=forward dst-port=4444 protocol=tcp
action=drop
* /ip firewall filter add chain=forward dst-port=5554 protocol=tcp
action=drop
* /ip firewall filter add chain=forward dst-port=9996 protocol=tcp
action=drop
* /ip firewall filter add chain=forward dst-port=995-999 protocol=udp
action=drop
* /ip firewall filter add chain=forward dst-port=53 protocol=tcp action=drop

Anda juga dapat menambah rule untuk pertahanan kemudian hari
anda dapat menganalisa port yang digunakan suatu aplikasi yang tidak anda
inginkan aplikasi tersebut mengakses ke internet
sebagai contoh ingin mematikan port yang digunakan MIrc
* /ip firewall filter add chain=forward dst-port=6665-6668 protocol=tcp
action=drop
anda bisa menggunakan AVG plus firewall untuk analisa program yang mengunakan
akses keluar
