Hmmm, really?
I mean, all intended packets are going through it, no errors
whatsoever. They are being marked correctly by iptables
and tc filter classifies according to mark. The only problem
seems to be the excess bandwidth distribution, which
leaves me to the question:

How could the hooks of IMQ and the excess bandwidth
distribution of HTB relate in this setup?

I hope you are understanding that I do not question your
knowledge. I'm just not fully persuaded of this yet, so I'd
like to discuss it a bit more.

And thanks a lot for the additional information you gave me!


Kind regards,

Leslie
