QoS and nat


Hi,

I just enabled QoS (htb qdiscs)
I wanted to specify the sources IPs in the u32 filters I've created, but when I did so with my private addresses, the filters didn't match packets anymore.

Of course these addresses are nated by iptables. So I concluded that the u32 filtering rules were used after nat POSTROUTING... am I right ?

Before trying u32 filters I looked a bit to using iptables, mangle & the set-mark target.
You can apply mangle rules to PREROUTING, INPUT, FORWARD, OUTPUT & POSTROUTING, can you do the same sort of things with tc u32 filters ?

Bye
