Hello,

I've tested removing de burst parameter in the htb config, and
I have de next results: [Attached File]

Is the HTB exact or not?

Now I've changed bw to 448Kbps or 56KBps, but in the graph
I have a maximum of 77.5KBps. Why???

Thanks!!!

Alexandra Alvarado

PD:  I can't use monitor_tc.pl, because iptables chain doesn't work
with PREROUTING : (
