I personally don't have much experience with it, but you could try using the
accounting features, i.e. using "count" in ipf.conf, of ipfilter to do the
counting. You should be able to reset those counters using ipf -z. The cia
package may be of some assistance as well. Man altq.conf has the altq config
info you should need.
