Re: QoS with netfilter

[Vinod Chandran <vinod_chandran@multitech.co.in>]

Hi,

If  you want to know how DSMARK and DSCP is used for QOS, check out the 
following link
http://opalsoft.net/qos/DS-29.htm
However, this doesnt use netfilter.

If you want to use netfilter, I think the best way is to have 
iptablerules in FORWARD, to set mark values on the basis of specific 
conditions,

like --src 192.168.1.0/24 -j MARK --set-mark 1.

This mark value can be further used in tc filter commands..
If this will suffice you,  I can elaborate more on this process.

Regards,
Vinod C
