Limit Bandwidth (not throughput)

[plexter]

Hello,

I am wondering if anyone has any insight as to how you can limit the total bandwidth used by a particular IP/host...etc? I know PF/ALTQ can prioritize and limit the total usuable connection speed but I am looking to do something more like a ratio once you reach X you are cut off. And I suppose in my case with the bandwidth you would be cut off for Y amount of time.

Is there any simple way of doing this? I have yet to see any software (knowingly) to do this on OpenBSD.

Thanks!

P.S. I appologize if PF is able to do this. Please point me to the topic in the man page if doable.
