Revision 1.10.4.1, Tue Sep 21 15:14:20 2004 UTC (14 years, 6 months ago) by tron
Branch: netbsd-2-0

Changes since 1.10: +5 -6 lines

Pull up revision 1.12 (requested by martti in ticket #866):
Explicitly flush (-Fa) rules when loading or reloading IPv4 and IPv6 rules,
rather than relying upon running "ipf -Fa" beforehand (which only flushes IPv4)
Should fix PR 26885 and PR 26857.
