iptables-init-debian

Init script for controlling iptables as a service in a Debian box. Tested in Debian Squeeze, Wheezy and Sid.

How to install iptables-init-debian

Download the script and place it in /etc/init.d/ with execution permissions, and use. I you want this script to be recognized as a service and autostart in debian, you must issue the following command:

update-rc.d iptables defaults

How to use the script

This script relies on iptables-save and iptables-restore commands, to save and read the rules in /etc/iptables.rules. Once installed, this file must be created, by saving current rules (save command).

Available command are:

• start: loads /etc/iptables.rules
• stop: flushes iptables completely, and enforces ACCEPT policy
• restart: convenience start & stop command
• save: saves the current rules to /etc/iptables.rules

Example:

service iptables start
service iptables stop
service iptables restart
service iptables status
