From 33b8e776056202aceaf4c90f465d0f4ee53432ac Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 17 Dec 2007 22:47:05 -0800 Subject: [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.
