Oops didn't see you were already patched - htb counters still see things 
at ip level.

FWIW You still can't really use 576000 - one of my modems would do it's 
aaal5/0 qos in whole cells so being slightly less, also if you 
start/restart the shaper on a live link the queue formed may never empty.

Running 286kbit on a 288kbit ATM rate line has never gone over for me 
and slowly drains if the modem buffer is full when started.

Andy.
