Hmm, I've tried ipfw pipe 2 config mask all bw 100Kbit/s ipfw add 10 pipe 2 tcp from localip to any 80 it appears to be working but I don't have enough connections on right =20 now to find out if it really gives 100kbit/sec to each or if it shares =20 the bw will come back with an update :) > I gave port 80 as an example but I need this configuration for =20 > limiting other services as well. > > If you have a 100mbps connection and only one client, you want him =20 > to only use 50kbps, not the full pipe.
