You can just set net.inet.ip.fw.one_pass to 0 and use more pipes to limit the maximum bandwidth. Let's say you want to limit the whole pipe to 1MBits/s and then limit user with UID 1001 to 128 KBits/s on your external interface fxp0 : % sysctl -w net.inet.ip.fw.one_pass=0 # First skip to the end of the rules if we're not on the outgoing # path through fxp0. % ipfw add 100 skipto 65000 all from any to any not xmit fxp0 # Limit user 1001 max bandwidth. % ipfw pipe 1001 config bw 128KBits/s % ipfw add 200 pipe 1001 all from any to any # System-wipe policy. % ipfw pipe 1 config bw 1MBits/s % ipfw queue 11 config weight 10 pipe 1 % ipfw queue 12 config weight 20 pipe 2 % ipfw add 210 queue 11 ... % ipfw add 220 queue 12 ... -- Jeremie Le Hen < jeremie at le-hen dot org >< ttz at chchile dot org >
