Subject: How to make conntrack to process all packets?
Date: Tue, 09 Jul 2013 20:09:15 +0200	[thread overview]
Message-ID: <51DC51CB.5050002@gmail.com> (raw)

Hi there,

We would like to use Ulogd's NFCT input for intelligent netflow-based 
statistics reporting. The problem is that the netfilter_conntrack 
doesn't process connections that don't go through the system (we have 
noticed and found in man conntrack /TABLES), which we need to process 
because of sniffing in promisc mode (we have forwarded traffic from 
different vlans). This doesn't work even when we do something like:
iptables -I PREROUTING -i eth9.10 -t raw -j CT

In fact we're looking for an opposite of NOTRACK. Do you have any idea 
how to setup or recompile the libnetfilter_conntrack or similar (ulogd2) 
so we get also flows not destined for the system?

Thank you, Petr
