Hi everybody,

I'm new to this list, so I appologize if a similar case has been covered already...
I have the configuration attached below...
The problem is that my traffic control doesn't work at all...
Clients from any of the private networks manage to download even with
256Kbits from the Internet...
The case is stranger because if I reboot the linux box, for a few minutes
the traffic shapping seems to work... I mean from a machine in subnet 192.168.1.8/29
I download with 16-20Kbits... but not always (most often I get at least 128Kbps).

A second question would be who has a higher priority:
a PC from a prio 8 class filtered by a prio 3 filter, or
a PC from a prio 3 class filtered by a prio 8 filter?

I'm open for further details if neccessary...

Thank you in advance,
MT
