I have some remarks. Why not let the 4 classes borrow unused bandwidth from each other? So if there is no other traffic then ftp, ftp can get 10Mbps. But as soone as there is some other traffic, the ftp traffic goes down. And if you want 4 isolated classes, why not just creating the 4 classes like this : 20:1 20:200 20:201 20:210 20:211 You have to create the htb (or cbq) classes. FIltering the traffic and placing in the classes is easy (you can filter on ports). Except maybe for the ftp traffic because that uses dynamic ports.
