I've been using ipfw+dummynet for traffic shaping for 7 or 8 years without problems (and have recently moved to pf+dummynet). I don't understand your comment about limiting bandwidth: An incoming packet is put on a queue that is emptied at no more than the (simulated) available outbound bandwidth. If the queue is full then incoming packets will be dropped. This is the same behaviour as any other router (or switch). What do you want/expect? > I hear many years about "trivial" >configuration per user bandwidth limit with pf+altq but never saw ANY >code... Note that I never mentioned per-user bandwidth with pf+altq - though it looks possible. There are some trivial traffic-shaping examples in pf.conf(5) but I will admit that I've never tried to actually use altq - I use dummynet because I need functionality that isn't present in altq. -- Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour.
