What I liked about using iptables-save and iptables-restore is that
calling /etc/init.d/firewall stop would put the firewall exactly back
into the state it was before; doing something like

iptables -X
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT
(and so on)

will just put the firewall back into its current default configuration,
which may or may not be what it was before calling /etc/init.d/firewall
start.
