Oh, what distro is it?  If Red Hat, put your rules in
/etc/sysconfig/iptables and it'll be auto-applied at boot.
Alternatively, set /etc/sysconfig/iptables-config's
IPTABLES_SAVE_ON_STOP and IPTABLES_SAVE_ON_RESTART to yes, and
whatever changes you make on-the-fly will be saved to
/etc/sysconfig/iptables automatically.
