Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

$ composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

$ php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Middleware

Open project into terminal and run this command to create middleware. This middleware we will use to block or restrict user access via IPs.

$ php artisan make:middleware BlockIpMiddleware

It will create a middleware file BlockIpMiddleware.php inside /app/Http/Middleware folder.

Open file and write this code into it.

<?php
  
namespace App\Http\Middleware;
  
use Closure;
use Illuminate\Http\Request;
  
class BlockIpMiddleware
{
    // Provide the IP list to be restrict  
    public $blockIps = ['whitelist-ip-1', 'whitelist-ip-2', 'whitelist-ip-3', '127.0.0.1'];
  
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure(\Illuminate\Http\Request): (\Illuminate\Http\Response|\Illuminate\Http\RedirectResponse)  $next
     * @return \Illuminate\Http\Response|\Illuminate\Http\RedirectResponse
     */
    public function handle(Request $request, Closure $next)
    {
        if (in_array($request->ip(), $this->blockIps)) {
          
            abort(403, "You are restricted to access the site.");
        }
  
        return $next($request);
    }
}

Register BlockIP Middleware

Open Kernel.php file from /app/Http folder. Search for $routeMiddleware. Add this line into it.

//...

protected $routeMiddleware = [
    
    ....

    'blockIP' => \App\Http\Middleware\BlockIpMiddleware::class,
];

//...

Now, we have a route middleware which restricts the IPs to access site.

Route Middleware Usage

Next,

We will use this route middleware to application routes to restrict IPs for those application URLs.

We can use in web.php as:

//...
  
use App\Http\Controllers\RSSFeedController;
use App\Http\Controllers\UserController;
   
//...

Route::middleware(['blockIP'])->group(function () {
    Route::resource('users', UserController::class);
    Route::resource('rss', RSSFeedController::class);
});

//...
