Re: [LARTC] ingress and egress

[Alexey Talikov <alexey_talikov@texlab.com.uz>]

You may route traffic from all devices to one imq and furthure 
control it by tc filter with mark or without it i.e. you may 
control traffic on two or more network devices (such ethx) simultaneous
i.e. traffic traverse over eth0 and eth1 can't be more then 100kbps, for example

You may create more then two devices
modbrobe imq numdevs=3 (numdevs=1...16)
ip link set imq0 up
ip link set imq1 up
ip link set imq2 up

iptables -t mangle -A PREROUTING -i eth0 -j IMQ --todev 0 (to imq0)
iptables -t mangle -A PREROUTING -i eth1 -j IMQ --todev 1 (to imq1)
etc

also possible
iptables -t mangle -A POSTROUTING -o eth0 -j IMQ --todev 0 (to imq0)
iptables -t mangle -A POSTROUTING -o eth1 -j IMQ --todev 1 (to imq1)
traffic traverse to imq devices and furthure hit to the network devices

(sorry for my pure English)
