Is iptables/netfilter stateful inspection firewall ?
I'd asked others but the answers were conflicted...:( :(
As "stateful packet inspection" seems to be developed by checkpoint ? If so, is the linux implementation really "stateful" ?
If yes, then can iptables/netfilter be used as a replacement for checkpoint firewalls ? like samba for NT servers ?
many thanks ;)
The answer is YES!!!!
visit www.netfilter.org and its documentation section to see a lot of positive press and proof about iptables' stateful-ness.

Re: need your help
what do you mean by "large number of packets"?? how much traffic are we talking about??
what do you mean by "the pc got hanged"??
post your iptables script here so someone can look at it and tell you if they see anything wrong with it...
iptables is used to configure netfilter, which works with the linux kernel, so i'm not sure what you mean when you ask for something "low level"...
if you answer these questions it'll be easier for someone to help you... you haven't given much info to work with so far... the more info you can provide about your setup and your situation, the better...
