For ICMP, specifically, there's a sysctl to control the rate (per second): # sysctl -d net.inet.icmp.icmplim net.inet.icmp.icmplim: Maximum number of ICMP responses per second For everything else, you'd want to use dummynet(4). -- Freddie Cash fjwc...@gmail.com _______________________________________________ freebsd-ipfw@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ipfw To unsubscribe, send any mail to "freebsd-ipfw-unsubscr...@freebsd.org"
