The box sits between our router to the internet and the clients. I have attached a mrtg graph to show the stats and one can see that every now and then the rate goes over the limit. This is the code I use for that client who has 64kbit from us and we give him 16kbit only with no borrowing. As you can see from the script I have tried to set the burst rate to as low as possible but it still goes over.
