We have several IP's NAT'd in from public interface. Even with that we noticed that 80% or so of the connection entries appear to be local to local traffic. We have the following subnets 10.40.16.0/24 (NAT'd public) 10.40.17.0/24 (internal data) 10.40.18.0/24 (internal data) 10.40.19.0/24 (internal data) 10.40.20.0/24 (NAT'd public) Public internface NAT's mostly to 10.40.16.0/24 IP's, and a couple on the 10.40.20.0/24 IP's. We have data/internal services on the 10.40.17.0/24 and 10.40.18.0/24. We see lots of connections from the 10.40.16.0/24 to the data/internal getting entered into the conntrack (as you would normally expect). So, is there any benefit of not conntracking these? Is so, how do I do that without breaking the NAT. I know I did this years ago, I just can't remember how. -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
