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.
