kolejność przetwarzania pakietów

[Tomasz Grobelny]

Jaka jest kolejnośc przetwarzania pakietów routowanych przez kernel? Chodzi mi 
o relatywne położenie łańcucha POSTROUTING i kolejek htb. Ewentualnie jeśli 
najpierw są kolejki htb a później POSTROUTING to gdzie można znaczyć pakiety 
aby później je kierować do odpowiednich klas?

Po pytaniach teoretycznych czas na coś bardziej ambitnego. Dlaczego to nie 
działa:
