PROBLEM: When starting Ubuntu, there is no firewall configuration. If
you create one (i.e. by using iptables), when you reboot it's gone. You
can install all kinds of tools (mostly GUI) to manage the firewall; but
they have their own issues, like having a learning curve on top of
iptables or just abstracting it too far away and not writing effective
rules (i.e. no stateful firewalling, no rate limiting, no logging).
SOLUTION: The attached script allows a user to store the firewall
configuration via '/etc/init.d/iptables save' so that whenever this
script starts (i.e. on system boot) the firewall configuration gets
reloaded. It has no companion GUI configuration; other packages exist
for GUI configuration. This script will however allow the easy
management of the firewall on servers with no X environment, where a
user would otherwise have to write their own.
