Hi,
After spectacularly failing to get HTB to proportionately distribute
excess bandwidth into multiple classes based on the rate, I decided to
hack my requirements. Now I'm creating multiple classes with the sum
of the bandwidths of the classes being equal to (OK, slightly less
than) the link ba

Hi Martin,
That you very much for your help.
I entered:ip address add 192.168.2.254/24 dev eth0
and also I added IP masquerading for this address range.
Everything now is working very well, just as I wanted.
Of course, If a user changed his IP address from 192.168.2.* range
into 192.

yes and yes, but it's a common mistake.

until the kernel knows the route/interface is dead and removes it, your metric 2

Oops again. While the note I indicated below is VERY informative, it's
not at all clear why HTB would complain if the rate is 78Kbit - that
corresponds to a quantum of 7800 bytes, which is plenty large.

What is the operation drop() in Qdisc_ops for? What are the requirements on

As far as I can tell, the classfull qdiscs just pass it on to child qdiscs
