Firewall

A Laravel package to help you block IP addresses from accessing your application or just some routes

Concepts

Blacklist

All IP addresses in those lists will no be able to access routes filtered by the blacklist filter.

Whitelist

Those IP addresses can

• Access blacklisted routes even if they are in a range of blacklisted IP addresses.
• Access 'allow whitelisted' filtered routes.
• If a route is filtered by the 'allow whitelisted' filter and the IP is not whitelisted, the request will be redirected to an alternative url or route name.

Routes

This package provides two middleware groups to use in your routes:

'fw-block-bl': to block all blacklisted IP addresses to access filtered routes

'fw-allow-wl': to allow all whitelisted IP addresses to access filtered routes

So, for instance, you could have a blocking group and put all your routes inside it:

Or you could use both. In the following example the allow group will give free access to the 'coming soon' page and block or just redirect non-whitelisted IP addresses to another, while still blocking access to the blacklisted ones.

IPs lists

IPs (white and black) lists can be stored in array, files and database. Initially database access to lists is disabled, so, to test your Firewall configuration you can publish the config file and edit the blacklist or whitelist arrays:

The file (for instance /usr/bin/firewall/blacklisted.txt) must contain one IP, range or file name per line, and, yes, it will search for files recursivelly, so you can have a file of files if you need:

Redirecting non-whitelisted IP addresses

Non-whitelisted IP addresses can be blocked or redirected. To configure redirection you'll have to publish the config.php file and configure:

Artisan Commands

To blacklist or whitelist IP addresses, use the artisan commands:

Exclusive for database usage

This is a result from firewall:list:

Facade

You can also use the Firewall Facade to manage the lists:

Return a blocking access response:

Suspicious events will be (if you wish) logged, so tail it:

Blocking Whole Countries

You can block a country by, instead of an ip address, pass country:<2-letter ISO code>. So, to block all Brazil's IP addresses, you do:

You will have to add this requirement to your composer.json file:

or

You can find those codes here: isocodes

Session Blocking

You can block users from accessing some pages only for the current session, by using those methods:

Firewall::whitelistOnSession($ip);
Firewall::blacklistOnSession($ip);
Firewall::removeFromSession($ip);
