Subject: Altering outgoing IP Address without Connection Tracking
Date: Tue, 06 Sep 2011 18:59:04 -0400 [thread overview]
Message-ID: <4E66A5B8.4030700@gmail.com> (raw)
I'd like to alter the outgoing IP address (from internal to external LB)
on all packets sent on a specific port, without incurring the overhead
of running conntrack. DNAT of course requires conntrack. But I can't
think of a reason why this simple substitution would require stateful
representation of packet flows. I was able to find one reference to
someone trying to mange the RAW packets [1] in 2008, but apparently
without success.
Is it currently possible to alter outgoing IP addresses without
connection tracking?
