Thanks! I´m not sure if I understand it correctly, but it seems that
shorewall is implementing the traffic shaping adaptively by default in
that it uses HTB to put classes in and then supplies the classes with
bandwidth according to their priority ...
In the setup I was using, testing showed that this didn´t work. That
made me set a low ceiling for some traffic which in turn made me think
that the traffic shaping should rather be adaptive.
But now I found that I overlooked to define a default class without
which it obviously couldn´t work. I changed the setup, and now further
testing is needed. --- If my understanding is correct, you´re right
and it´s easy to use but takes a while to learn :)
One thing I don´t understand is that there´s no rule for the tcp-ack
packages in the tcrules file. When you look at the sections titled
"Configuration to replace Wondershaper" and "A simple setup" in ,
they want to speed up downloads by sending out acknowledgements fast:
"We add a class for tcp ack packets with highest priority, so that
downloads are fast."
They do that in the tcclasses file, but there´s no rule to mark such
packages in the tcrules file they use in these examples. How does that
