Iptables modules

Hi everybody, I'm new at this list and I'm not an expert. I use a Red Hat 9 Linux. 
So I need to know how I can view in my Linux OS the modules the kernel has or load at boot time, for example for implement  FTP connection tracks or TOS.

Another question: where can I get the modules I don't have now ??? And what can I install them ???

Thanks a lot, regards.

Alejandro.

iptables -A ... -p <proto> ...

or

iptables -A ... -m <module> ...

(See: man iptables)

or

modprobe <iptables_module>

(See: man modprobe)

You can find the netfilter modules that you have installed in:

/lib/modules/`uname -r`/kernel/net/ipv4/netfilter

First:
 Try simply using them...
 If autoloading enabled in your kernel then they will be loaded when 
needed...
Second:
 Use modprobe command.
