Hello, Bug-followup. It is still valid for 8.2-STABLE: gateway# ipfw add 50000 allow ipv6-icmp from any to 2001:470:1f09:hhhh::/64= ,2001:470:hhhh:1::/64,2001:470:hhhh:2::/64 icmp6types 1,2,3,4,128,129 keep-= state ipfw: bad netmask ``470:1f09:hhhh::/64'' gateway# uname -a FreeBSD gateway.home.serebryakov.spb.ru 8.2-STABLE FreeBSD 8.2-STABLE #0: F= ri Apr 15 16:57:44 MSD 2011 lev@vmware-8-32.home.serebryakov.spb.ru:/us= r/obj/nanobsd.gateway-net5501/usr/src/sys/NET5501 i386 It is very annoying bug, because "allow" rule can be divided into one-rule-per-network, but "deny ... NOT IPv6,IPv6,..." is hard to emulate (with multiple skipto rules). --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
