From 4095ebf1e641b0f37ee1cd04c903bb85cf4ed25b Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Tue, 28 Jun 2005 12:49:30 -0700 Subject: [PATCH] [NETFILTER]: ipt_CLUSTERIP: fix ARP mangling This patch adds mangling of ARP requests (in addition to replies), since ARP caches are made from snooping both requests and replies.
