iptables

[JD]

Hi all,
On redhat based linuxes, you enable the firewall by
either using the "services" gui or use the command
line chkconfig.
Once enabled, it always starts at boot(assuming you
have set up your firewall rulesfile which is
/etc/sysconfig/iptables).
As I am indeed new to ubuntu, I need way of
"enabling" iptables and thus having it always
start at boot automatically.

Thanks for any tips.

Cheers,

JD
