[LARTC] Packet marking for ingress shapping and NET

[Patrick Spousta]

Hi,
I have typical situation, local LAN with private addresses, translated 
via NAT to internet. I need to shape ingress traffic (from internet to 
local LAN) in several HTB queues accorting to destination (private not 
public) IP. So I need mark packets to divide them to corresponding 
queue. According to http://www.docum.org/stef.coene/qos/kptd/ I thing I 
have only one way how to do it, because MARK in PREROUTING is before (de)NAT

PREROUTING (de)NAT
               V
FORWARD    marking
               V
FORWARD   put to IMQ
               V
          HTB shapping
               V
        routing decision
               V
        output interface

It has a small problem. After PREROUTING some packets are routed to 
INPUT (packets intended for this machine for local processes)

Does exists solution how to NAT and MARK in PREROUTING, but in this order?
