[KLUG Members] iptables: missing a module?

[Andrew Thompson]

I've been wanting to get iptables working on my system for awhile now, and 
after reading the current iptables thread, decided to try that iptables -L 
command. It keeps coming back with this error message:

>>iptables v1.2.4: can't initialize iptables table `filter': iptables who? 
(do you need to insmod?)
>>Perhaps iptables or your kernel needs to be upgraded.

Can anyone tell me what I need to do here, and how? If I need to build a 
module (it looks like I need ip_filter, and don't have it), can I do this 
without having the rebuild the whole kernel? I've been through THAT mess a 
couple of times already!
