Subject: Is there way to bypass conntrack?
Date: Wed, 03 Sep 2003 10:47:06 -0700	[thread overview]
Message-ID: <3F56291A.90003@tigry.net> (raw)

I'd really like to have some way to bypass ip_conntrack for some 
packets. Basically I need to run very intensive port scanning through my 
firewall and as soon as ip_conntrack loaded it dies within seconds from 
syn flood. Increase limit doesnt work becuase I need about  127000 
packets to be sent from different source ports. So far I just keep 
contrack unloaded and firewall works fine as pure stateless filter. But 
now I need statefull inspection on this machine for some IPs. So the 
question - is it possible to avoid connection tracking for some specific 
IPs?

Thanks!

Andrey
