Could you try this firewall: ipfw flush ipfw add pipe 1 ip from any to any out ipfw add pipe 2 ip from any to any out ipfw pipe 1 config bw 1500Kbit/s dst-ip 0xffffffff ipfw pipe 2 config bw 25Mbit/s With net.inet.ip.fw.one_pass set to 0 all packets should pass though both pipes. -- Alex Articles based on solutions that I use: http://www.kruijff.org/alex/index.php?dir=docs/FreeBSD/
