From a46bf7d5a81b350cd204b82bd25ee6ffbc2967d4 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Fri, 26 Jan 2007 01:07:30 -0800 Subject: [NETFILTER]: nf_nat_pptp: fix expectation removal When removing the expectation for the opposite direction, the PPTP NAT helper initializes the tuple for lookup with the addresses of the opposite direction, which makes the lookup fail.
