Hello, 

I'm a novice in kernel.

I'd like to know the relationship between Netfilter and iptables.

Netfilter includes iptables?? -_-;;

are they independent??


Second quesetion is..

we can write module program using netfilter.

but I didn't see the module program using iptables..

I could see just script using iptables.

is there any way writing a module program using iptables?


I'm very confused about them.. -_-;;

plz, help me.. ^^;;


Thanks very much.

If i'm not mistaken, netfilter is the linux kernel module itself, while
iptables is "just" the programm to control netfilter.

So you use iptables to modify netfilter rules.

hope that helps,
