Struggling with classes not work

Hi Mark:

Sorry, you are out of luck.  BOOTP packets cannot be pushed through 
classification.  They actually go through their own handler logic 
(server/bootp.c) and it does not invoke the classify_client() function, 
and even if it did it does not go through other critical points where 
classification has an impact.

Regards,

Thomas
