Hello, 

Can you post the scripts you are using ?

Thanks,
I know the older version of this diagram and this one is quite the same I told below but the problem is the same for the DNAT. I made another test. I change the DSCP value in the PREROUTING table and I put an ingress policing which match this new dscp value but the filter doesn't match nothing (I work on a Linux 2.6.17).
With my test, the older version ( http://www.imagestream.com/~josh/PacketFlow.jpg) of the diagram seams more exactly.

Have you an idea ?

Hi,

I find this diagram which details the kernel packet traveling :
http://www.docum.org/docum.org/kptd/
Is it up to date ?
I made some test and I put a DNAT rules in the PREROUTING table of an interface and I attach it a ingress policy, the dst IP wasn't changed. the DNAT it isn't yet make.

I've another question (I'm not sure is it the good mailing list), for the fragment packet, I see the ingress policy doesn't work correctly and I'd like to know where in the kernel travel of the packet the fragment are re-assemble ? At the NAT or in the routing ?

Thanks,
Edouard.
