例如限制，内网192.168.1.253的8612端口的速度

1.内网192.168.1.253   端口8612——-标记连接

/ip firewall mangle

add action=mark-connection chain=prerouting comment="" disabled=yes

new-connection-mark=8612 passthrough=yes protocol=tcp src-address=

192.168.1.253 src-port=8612

2. 内网192.168.1.253   端口8612 ——-标记数据包

/ip firewall mangle

add action=mark-packet chain=prerouting comment="" disabled=yes

new-packet-mark=8612 passthrough=yes src-address=192.168.1.253

3.限速

/queue tree

add burst-limit=0 burst-threshold=0 burst-time=0s disabled=yes limit-at=

1000000 max-limit=1000000 name=8612 packet-mark=8612 parent=global-out

priority=1 queue=default
