iptables

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?

Managed hosting firewall vs managing own firewall

I posted on stackoverflow as to the overall benefits of managed hosting vs non-managed hosting. The more I think about it, it seems to boil down to one question: should I use a managed host because they take care of the firewall, or would I be okay managing my own, software firewall?
