From 7918d212df31fb7ddfb317c5a8dccdcec647d754 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sat, 4 Feb 2006 02:19:46 -0800 Subject: [PATCH] [NETFILTER]: Fix check whether dst_entry needs to be released after NAT After DNAT the original dst_entry needs to be released if present so the packet doesn't skip input routing with its new address. The current check for DNAT in ip_nat_in is reversed and checks for SNAT. Signed-off-by: Patrick McHardy Signed-off-by: David S.
