Also, as a point of reference, here's how to flush ALL the current iptables rules:

#!/bin/sh

echo "Stopping firewall and allowing everyone..."

iptables=/sbin/iptables

$iptables -F

$iptables -X

$iptables -t nat -F

$iptables -t nat -X

$iptables -t mangle -F

$iptables -t mangle -X

$iptables -P INPUT ACCEPT

$iptables -P FORWARD ACCEPT

$iptables -P OUTPUT ACCEPT

There are actually more tables than that. At least -t raw and -t security. Instead of hard coding, use /proc/net/ip_tables_names
