From: Patrick McHardy Date: Tue, 18 Dec 2007 06:47:05 +0000 (-0800) Subject: [NETFILTER]: Add CONFIG_NETFILTER_ADVANCED option X-Git-Tag: v2.6.25-rc1~1162^2~990 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=33b8e776056202aceaf4c90f465d0f4ee53432ac;p=linux-2.6 [NETFILTER]: Add CONFIG_NETFILTER_ADVANCED option The NETFILTER_ADVANCED option hides lots of the rather obscure netfilter options when disabled and provides defaults (M) that should allow to run a distribution firewall without further thinking. Defaults to 'y' to avoid breaking current configurations. Signed-off-by: Patrick McHardy Signed-off-by: David S.
