Subject: Logging NAT Translations
Date: Fri, 18 May 2007 20:15:32 -0700	[thread overview]
Message-ID: <ae1f24730705182015j533102bah985e9ad0e905cd2a@mail.gmail.com> (raw)

I can't believe this isn't a FAQ; I apologize if I missed something in
my searches.

Is there a way to log connections along with all of their NAT translation data?

I am using a Debian (Sarge) system to SNAT guest users from private
address space to the Internet, and I need to keep a record that
includes both their internal and external addresses.

Simply logging before the SNAT rule leaves out the external address,
leaving me only with the original RFC1918 source address.
/proc/net/ip_conntrack has the information I need, but no way to send
it to the log it at the beginning and/or end of the session.

There HAS to be an easy way to do this!  Right?

Thank you...
