hi all
i want to my users that connect with pppoe and hotspot can access to 192.168.88.100 with speed at 5mbps(only this address)
the users ip pool is 192.192.192.0/24
192.168.88.100 is connected to ether2 and
192.192.192.0/24 is connected to ether1

1st mark the packet: IP/FIREWALL/MANGLE
chain=forward action=mark-packet new-packet-mark=HTTP-FULL passthrough=no dst-address=192.168.88.100 dst-port=80
protocol=tcp
AND THEN USE QUEUE TREE:
name="HTTP-QUEUE" parent=global-out packet-mark=HTTP-FULL limit-at=5M queue=default priority=1 max-limit=5M burst-limit=0 burst-threshold=0 burst-time=0s
