ipfw add 10000 pipe 1 tcp from <my_ip> 80 to any ipfw pipe 1 config bw 5Mbits/s queue 10 anyway you look at it, if it the limiting starts to work, I start to go up in mbufs.. I don't know who's responsible for it.. ? If I just use a simple ipfw rule, it works, I don't lose any mbufs, but a combination with dummynet, if it works, it means my box will reboot later on :) So I have to remove the ipfw rule, before my mbufs go dangerously high, and as soon as I remove it, mbufs drop from 7500 or so to like 1500 (their normal)..
