+## Firewall integration in systemd
+
+
+
+Simple tool to load your **iptables** rules at boot time. It integrates with systemd as a multi instance service.
+
+
+
+##### 1/ Install the tool
+
+Launch the `./install.sh` script as root.
+
+##### 2/ Define your rules
+
+Place a bash script defining your **iptables** rules into `/opt/firewall/<config_name>.fw` where `<config_name>` is an arbitrary name that makes sense to you.
+
+##### 3/ Enable at boot
+
+To enable your rules to load at boot time, simply run `systemctl enable firewall@<config_name>.service`.  If you want to execute your script explicitly run `systemctl start firewall@<config_name>.service`.
