# Debian Light Firewall

## Introduction

Ce firewall léger est inspiré de celui fournit par [Nicolargo sur cette page](http://blog.nicolargo.com/2013/03/mes-5-premieres-minutes-sur-un-serveur-debian.html).

## Installation

### Makefile

L'installation se fait par un makefile:

```bash
make install
```

#### Configuration

Editer le fichier `/etc/firewall/firewall.conf` et tester votre configuration


#### Test du firewall

Le test se fait en tapant la commande suivante:

```bash
$ sudo lightwall test
```

#### Enable the firewall
Once tested (you should at least be able to open a new ssh session when firewall is active with new configuration), you can enable and start it.
```bash
sudo systemctl enable firewall.service
sudo systemctl start firewall.service
```

#### Stopping firewall
Stopping will drop all connections (which is not really cool)

So to really clear all rules use (and open all in/out traffic):
```bash
sudo service firewall clear
```

And to really drop all rules use (and close all in/out traffic):
```bash
sudo service firewall dropall
```
