iptables is the same on rhl & debian.
The debian part is all about:
you setup the firewall,
and if you have finished, you save your settings with iptables-save to
/var/lib/iptables/active. After that, you clean your firewall, flush all
chains, and erase all chains that aren't mandatory. (iptables -F ;
iptables -X) After cleaning, you save this also as
/var/lib/iptables/inactive.
The default debian installation doesn't link /etc/init.d/iptables to the
runlevels, so you have to make an S99iptables symlink in rc2.d pointing
to /etc/init.d/iptables and the corresponding K01iptables in rc{0,6}.d
directories.
My /etc/default/iptables looks like:
iptables_command=iptables
enable_autosave=true
enable_save_counters=true
If these are done, reboot the machine, and you'll see that all your
rules get up after a successful boot.
