Hi, I'm running a Linux server that - from time to time - faces heavy load and the conntrack table overflows. Since it's iptables firewall ruleset is very simple I'd like to turn it to stateless mode. I know that iptables can operate in stateful connection tracking mode and in a stateless mode.

My firewall rules are all in place I'm pretty sure that they are stateless but my question is how can I verify that the firewall is really operating in stateless mode?
