hi, can you show me the output of ipfw show and ipfw pipe show Reading your questions, i have the feeling you are doing something wrong in the commands. For the last one, the client will keep generating its stream of data, it is just after going through the pipe that you will see the limitation in effect. cheers luigi ----------------------------------+----------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
