All,

Below is the lead from the auto generated IPTABLES script. It would seem to me that the INPUT policy should be 'REJECT' instead of 'ACCEPT'.

Thanks - Dan

(the script goes on to allow specific services)

i see this a lot on red hat boxes... usually there's a "catch-all" rule at the end of the RH-Firewall-* chain which does a DROP or a REJECT...

but yes, optimally you'd wanna get rid of those RH-Firewall-* rules, set your policies set to DROP, and make your own rules...
