I am trying to establish some means to control the IP bandwidth available for a number of NAT-ed classes. Each class or collection of classes should not use receive less than a certain assigned bandwidth if they need it. In the same time I want to make sure that each indvidual IP address in these classes has it's own restrictions: that is a minimum B/W (if available), maximum bandwidth, burst. Is this possible using HTB? From the documentation I see that only leaf nodes can have filters - does this mean that I cannot create and apply a filter for a whole class? Sebastian
