Answer 1

Maybe this will help someone. I just catch route name and check if they are in array. If yes just redirect. This is event listener.

services.yml

project.loggedin_listener:
      class: Project\FrontBundle\EventListener\LoggedInListener
      arguments: [ "@router", "@service_container" ]
      tags:
        - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }

listener:

namespace Project\FrontBundle\EventListener;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpFoundation\RedirectResponse;

class LoggedInListener {
    private $router;
    private $container;

    public function __construct($router, $container)
    {
        $this->router = $router;
        $this->container = $container;
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $container = $this->container;
        $accountRouteName = "_homepage";

        if( $container->get('security.context')->isGranted('IS_AUTHENTICATED_FULLY') ){

            $routeName = $container->get('request')->get('_route');
            $routes = array("admin_login","fos_user_security_login","fos_user_registration_register","fos_user_resetting_request");
            if(in_array($routeName, $routes)){
                $url = $this->router->generate($accountRouteName);
                $event->setResponse(new RedirectResponse($url));
            }

        }

    }
}
