You might want to look into using the regular iptables service instead
od custom firewall scripts. The service uses iptables-save and
iptables-restore which are designed to install all iptables rules
atomically.
If you end up with a typo in your script you end up with a partially
initialized firewall but iptables-restore first parses the entire rule
set and doesn't touch the current rules at all if it finds an error
making the process much more robust.
