if you use bridge, execute
/interface bridge settings set use-ip-firewall=yes
Thank's !! I forgot this
so , take a look to this example :
/ ip firewall mangle
add chain=prerouting protocol=tcp dst-port=80 action=mark-connection \
new-connection-mark=http_conn passthrough=yes
add chain=prerouting connection-mark=http_conn action=mark-packet \
new-packet-mark=http passthrough=no
add chain=prerouting p2p=all-p2p action=mark-connection \
new-connection-mark=p2p_conn passthrough=yes
add chain=prerouting connection-mark=p2p_conn action=mark-packet \
new-packet-mark=p2p passthrough=no
add chain=prerouting action=mark-connection new-connection-mark=other_conn \
passthrough=yes
add chain=prerouting connection-mark=other_conn action=mark-packet \
new-packet-mark=other passthrough=no
/ queue simple
add name="main" target-addresses=10.0.0.0/16 max-limit=256000/1000000
add name="http" parent=main packet-marks=http max-limit=240000/500000 priority=1
add name="p2p" parent=main packet-marks=p2p max-limit=64000/64000 priority=8
add name="other" parent=main packet-marks=other max-limit=128000/128000 priority=4
this limit the traffic for all network or for client ? ( If 4 client , we have 256k/4 or 256k*4 ? )
Thank's in advance.
