Limit bandwidth per extension ( .exe, .iso, .mpg, .mp3, dll )

Buat rule firewall yang dimasukkan addrest list

/ip firewall filter add chain=forward \
src-address=192.168.1.0/24 protocol=tcp content=.exe \
action=add-dst-to-address-list address-list=cekek \
address-list-timeout=01:00:00
/ip firewall filter add chain=forward \
src-address=192.168.1.0/24 protocol=tcp content=.iso \
action=add-dst-to-address-list address-list=cekek \
address-list-timeout=01:00:00
/ip firewall filter add chain=forward \
src-address=192.168.1.0/24 protocol=tcp content=.mpg \
action=add-dst-to-address-list address-list=cekek \
address-list-timeout=01:00:00
/ip firewall filter add chain=forward \
src-address=192.168.1.0/24 protocol=tcp content=.mp3 \
action=add-dst-to-address-list address-list=cekek \
address-list-timeout=01:00:00

time diatas menunjukkan 1 jam. bisa diatur menurut kebijakan anda
bisa juga ditambahkan rule sesuai kebutuhan.

kemudian kita lakukan mangle untuk marking paket yang berasal dari address list diatas seperti ini:

/ip firewall mangle add chain=forward \
protocol=tcp src-address-list=cekek \
action=mark-packet new-packet-mark=cekek-bw

Lalu untuk yg terakhir kita masukkan simple queue dari paket mark diatas

/queue simple add name=download-files \
max-limit=64000/64000 packet-marks=cekek-bw
