There isn't much of a setup... I just take my private network on eth1,
masquerade it and shape it over eth0...
Don't know what to say... take a look at the output, maybe you'll find
something wrong.
Don't mind the origninal numbering (of the classes and packet marking)
I used in my first message as I changed it for easier reading...
anyway, i'm attaching my original shaping script to this message.

One more question: I always use weight = rate / 10.
Why does weight has these strange values in my output?

Thank you for your support,
Mugur

Mh.  I tested it with htb and there is only prio 0-7.

I mean the shaping setup (classes, filters, ...).

All sent counters are 0 execpt for the root class.  So I'm quit sure that your 
filters are not working.

I don't know.  Like I said, I use htb.

Euh.  You don't have any filters?  How do you redirect traffic to a class?  
You need some filters to do so.
