I can now confirm that these two commands do exactly what I mentioned =20 originally. All outbound connections towards any host port 80 will have a maximum =20 bandwidth of 100Kbit/s individually ( output ) ipfw pipe 2 config mask all bw 100Kbit/s ipfw add 10 pipe 2 tcp from localip to any 80 Problem solved :) > 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 =20 > right now to find out if it really gives 100kbit/sec to each or if =20 > it shares 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.
