Seems you have no choice other than set your rate equal with 1Kbit. I've
made some tests to configure such a bandwidth, and that was the small
rate that I could get it.

OK, I will use rate 1kbit. Therefore r2q should be 1, right?
Thanks,
Thomas

Hi Thomas!
The smallest rate you can use with r2q=1 is mtu*8 kbit (12kbit in most
cases). You can skip r2q and use quantum=125 bytes, but that is probably not
such a good idea...

The HTB FAQ page from Devik's site says that you should use at least
4kbit for realiable operation of HTB. So it's hard to say what could be
the best minimal quantum value in this case. It's not a good ideea to
use a value smaller than 1500 bytes, so leave the quantum at this value
and ignore the warning messages from syslog, or use the patch against
2.4.20 to skip these type of errors.

Quantum must be > 1500 so the internal caculations of htb are good.
And 60.000 is the maximum hard coded in htb.
So try to take r2q so
smallest_rate/r2q > 1500
biggest_rate/r2q < 60000
Quatum is only used if you have a parent class that's has remaining bandwidth.
I don't know if this is the case in your situation.
