README

Note : This project was forked from Spomky-Labs/IpFilterBundle because is abandoned.

Description

This bundle will help you to restrict access of your application using IP addresses and ranges of IP addresses.

It supports both IPv4 and IPv6 addresses and multiple environments.

For example, you can grant access of a range of addresses from 192.168.1.1 to 192.168.1.100 on dev and test environments and deny all others.

Please note that this bundle has bad results in term of performance compared to similar functionality offered by a .htaccess file for example.

This bundle required or used

Package	Version
PHP	^7.1
Symfony	^4.0\|~5.0
Doctrine	^2.6

Policy

Please note that authorized IPs have a higher priority than unauthorized ones. For example, if range 192.168.1.10 to 192.168.1.100 is unauthorized and 192.168.1.20 is authorized, then 192.168.1.20 will be granted.

Installation

Installation is a quick 4 steps process:

Download the bundle
Enable the Bundle
Create your model class
Configure the application

##Step 1: Install the bundle##

The preferred way to install this bundle is to rely on Composer:

composer require "coosos/ip-filter-bundle" "~4.1"

##Step 2: Enable the bundle##

Enable the bundle in config/bundles.php:

<?php
// config/bundles.php

return [
    // .....
    Coosos\IpFilterBundle\CoososIpFilterBundle::class => ['all' => true]
    // .....
];

##Step 3: Create IP classes##

This bundle needs a database to persist filtered IPs.

Your first job, then, is to create Ip classes for your application. These classes can look and act however you want: add any properties or methods you find useful.

In the following sections, you'll see an example of how your classes should look.

###Ip class:###

<?php
// src/Entity/Ip.php

namespace App\Entity;

use Coosos\IpFilterBundle\Entity\Ip as BaseIp;
use Doctrine\ORM\Mapping as ORM;

/**
 * Ip
 *
 * @ORM\Table(name="ips")
 */
class Ip extends BaseIp
{
    /**
     * @var integer $id
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    public function getId()
    {
        return $this->id;
    }
}

##Step 4: Configure your application##

Set your classes and managers

# config/packages/config.yml
sl_ip_filter:
    ip_class: App\Entity\Ip

If you have your own managers, you can use them. They just need to implement Coosos\IpFilterBundle\Model\IpManagerInterface.

# app/config/config.yml
sl_ip_filter:
    ...
    ip_manager: my.custom.ip.entity_manager

###Security Strategy###

In order for this bundle to take effect, you need to change the default access decision strategy, which, by default, grants access if any voter grants access.

You also need to place your site behind a firewall rule.

# config/packages/security.yml
security:
    access_decision_manager:
        strategy: unanimous
…
firewalls: 
    my_site:
        pattern: ^/
        anonymous: ~

access_control:
    - { path: ^/, roles: IS_AUTHENTICATED_ANONYMOUSLY }

How to

Small example

How to grant access for 192.168.1.10 on dev and test environments and deny all others?

<?php

use Coosos\IpFilterBundle\Model\IpManagerInterface;

/** @var IpManagerInterface $ipManager */
$ipManager = $this->container->get('sl_ip_filter.ip_manager'); //Use this line, even if you use a custom IP manager

//Create your IP
$ip = $ipManager->createIp();
$ip->setStartIp('192.168.1.10') // Use only setStartIp() if it's a simple IP
   ->setEnvironment(['dev', 'test']) // You can also use 'prod'
   ->setAuthorized(false);

$ipManager->saveIp($ip);

// If you need to block or authorized an IP range, you must also specify an end ip with the setEndIp() method
$ip = $ipManager->createIp();
$ip->setStartIp('10.30.0.0')
   ->setEndIp('10.30.0.255')
   ->setEnvironment(['dev', 'test'])
   ->setAuthorized(true);

$ipManager->saveIp($ip);

Network support

Networks can be supported using a Range object. You just need to get first and last IP addresses. This bundle provides a range calculator, so you can easily extend your range entity using it.

<?php

use Coosos\IpFilterBundle\Model\IpManagerInterface;

/** @var IpManagerInterface $ipManager */
$ipManager = $this->container->get('sl_ip_filter.ip_manager');

//All addresses (IPv4)
$range1 = $ipManager->hydrateModelWithIp('0.0.0.0/0');
$range1->setEnvironment(['dev', 'test'])
       ->setAuthorized(false);

$ipManager->saveIp($range1);

//My local network (IPv4)
$range2 = $ipManager->hydrateModelWithIp('192.168.0.0/16');
$range2->setEnvironment(['dev', 'test'])
       ->setAuthorized(true);

$ipManager->saveIp($range2);

//Another local network (IPv6)
$range3 = $ipManager->hydrateModelWithIp('fe80::/64');
$range3->setEnvironment(['dev', 'test'])
       ->setAuthorized(true);

$ipManager->saveIp($range3);
