Sure, something like this might do you good... /sbin/ipfw add pipe 1 ip from foo.bar.ip.here to any /sbin/ipfw add pipe 1 ip from any to foo.bar.ip.here /sbin/ipfw pipe 1 config bw 45Kbit/s delay 150ms Which would create a 45kbit pipe for all inbound and outbound traffic for said foo ip, and add 150 ms of latency to packet delivery. You can do more fancy things with other dummynet options: `man dummynet` or http://www.iet.unipi.it/~luigi/ip_dummynet/ >Gordon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
