FWaaS plugin

FWaaS (Firewall-as-a-Service) is a Neutron extension that introduces Firewall feature set.

This repo contains all necessary files to build FWaaS Fuel plugin.
Currently the only supported Fuel version is 6.0.

Building the plugin
1. Clone the fuel-plugins repo from
2. Install Fuel Plugin Builder using documentation from the fuel-plugins repo
3. Execute fpb --build <path>, where <path> is the path to the plugin's main
folder (fwaas)
4. fwaas-plugin-1.0.0.fp plugin file will be created
5. Move this file to the Fuel master node and install it using
the following command: fuel plugins --install fwaas-plugin-1.0.0.fp
6. Plugin is ready to use and can be enabled via Fuel WebUI ('Settings' tab)

Deployment details

FWaaS deployment requires only adding a couple parameters in neutron.conf and
enabling FWaaS tab in Horizon.

Accessing FWaaS functionality
Firewall settings can be found in Openstack Dashboard:
Project -> Network -> Firewall

Please use official Openstack documentation to obtain more information:

5. [Limitations - OS compatibility, etc.](#limitations)

## Overview

This is FWaaS plugin for FUEL, which provides an ability to setup FWaaS Neuton extention
that introduces Firewall feature set.

## Module Description

FWaaS Neutron extention provides additional perimeter firewall management to Networking.
FWaaS uses iptables to apply firewall policy to all Networking routers within a project.
It supports one firewall policy and logical firewall instance per project.

## Setup

### What FWaaS affects

* During installation manifests add a couple options in neutron.conf and enable FWaaS tab in Horizon.

### Beginning with VPNaaS

How to use FWaaS you can find here:

## Reference

Here, list the classes, types, providers, facts, etc contained in your module.
This section should include all of the under-the-hood workings of your module so
people know what the module is touching on their system but don't need to mess
with things. (We are working on automating this section!)

## Limitations

This plugin supports only the following OS: CentOS 6.4 and Ubuntu 12.04.
