Subject: do not nat gre packets
Date: Sun, 24 Feb 2008 20:04:22 +0100	[thread overview]
Message-ID: <47c1bfc1.0637560a.59d2.ffffbd8b@mx.google.com> (raw)

Hello, 
  
I am currently using iptables version 1.2.7a and encountered the following
issue. When using a GRE (over ipsec) tunnel without the optional GRE key
field, Netfilter cannot find a unique tupel for all GRE packets. This makes
the connection tracking fail. The source code shows only a GRE over PPTP
implementation. My understanding is that I need to extend the iptables
implementation of version 1.2.7a to enable the connection tracking. Is this
true? Was this fixed in a version following 1.2.7a? 
  
I would appreciate any information on this. 
  
 
Kind regards,

Friedrich
