Iptables the "Debian" way?

[Ben Russo <ben@muppethouse.com>]

I am used to using RedHat, whereby I make sure I have the iptables 
package installed and I can use "chkconfig" to see if iptables has 
system-V runtime setup to be on or off, and the iptables-save data goes 
into /etc/sysconfig/iptables for reload on reboot (or change of SysV 
init level).

What is the "Debian" way of doing this?
I have iptables installed and I can add iptables rules and they work, 
but I did a grep for "iptables" in /etc/init.d/* and nothing matches, 
and I searched through /etc for files that contain firewall rules and 
didn't see any?

Also, I installed Webmin and the webmin-iptables module.  But when I go 
to the webmin interface there is no iptables module being shown (yes I 
restarted apache, webmin and my browser).  Any hints?
