Trust Cloudflare's Proxies for Laravel

Add Cloudflare ip addresses to trusted proxies for Laravel.

Installation

1. Install package using composer:

composer require monicahq/laravel-cloudflare

1. Configure Middleware

Replace TrustProxies middleware in your bootstrap/app.php file:

->withMiddleware(function (Middleware $middleware) {
    $middleware->replace(
        \Illuminate\Http\Middleware\TrustProxies::class,
        \Monicahq\Cloudflare\Http\Middleware\TrustProxies::class
    );
})

Custom proxies callback

You can define your own proxies callback by calling the LaravelCloudflare::getProxiesUsing() to change the behavior of the LaravelCloudflare::getProxies() method. This method should typically be called in the boot method of your AppServiceProvider class:

use Illuminate\Support\ServiceProvider;
use Monicahq\Cloudflare\LaravelCloudflare;
use Monicahq\Cloudflare\Facades\CloudflareProxies;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        LaravelCloudflare::getProxiesUsing(fn() => CloudflareProxies::load());
    }
}

How it works

The middleware uses Illuminate\Http\Middleware\TrustProxies as a backend.

When the cloudflare ips are detected, they are used as trusted proxies.

Refreshing the Cache

This package retrieves Cloudflare's IP blocks, and stores them in cache. When request comes, the middleware will get Cloudflare's IP blocks from cache, and load them as trusted proxies.

You'll need to refresh the cloudflare cache regularely to always have up to date proxy.

Use the cloudflare:reload artisan command to refresh the IP blocks:

php artisan cloudflare:reload

Suggestion: add the reload command in the schedule

Add a schedule to your routes/console.php file to refresh the cache, for instance:

use Illuminate\Support\Facades\Schedule;

Schedule::command('cloudflare:reload')->daily();

View current Cloudflare's IP blocks

You can use the cloudflare:view artisan command to see the cached IP blocks:

php artisan cloudflare:view

Option: publish the package config file

If you want, you can publish the package config file to config/laravelcloudflare.php:

php artisan vendor:publish --provider="Monicahq\Cloudflare\TrustedProxyServiceProvider"

This file contains some configurations, but you may not need to change them normally.

Running tests for your package

When running tests for your package, you generally don't need to get Cloudflare's proxy addresses. You can deactivate the Laravel Cloudflare middleware by adding the following environment variable in your .env or phpunit.xml file:

LARAVEL_CLOUDFLARE_ENABLED=false
