OK, finally I have made cbq run ! now I would like to know if it is posible to limit a range of IP to a speed. something like this : from 192.168.1.1 to 192.168.1.21 limit to 128K I don't whant to limit each IP to 128K, what I would like to do is limit all 20 IP to have a max of 128K. Is it posible?
