将“/ inicio”定义为主页或变通方法路由未命中配置

I have a site with some static pages and I have defined as follow in routing_pages.yml file:

index:
    pattern:  /inicio
    defaults: { template: 'FrontendBundle:Site:index.html.twig' }

contact_one:
    pattern:  /contact_one
    defaults: { template: 'FrontendBundle:Site:contact.html.twig' }

location:
    pattern:  /horario
    defaults: { template: 'FrontendBundle:Site:location.html.twig' }

payment:
    pattern:  /pagos
    defaults: { template: 'FrontendBundle:Site:payment.html.twig' }

question:
    pattern:  /preguntas
    defaults: { template: 'FrontendBundle:Site:question.html.twig' }

questionb:
    pattern:  /preguntasb
    defaults: { template: 'FrontendBundle:Site:questionb.html.twig' }

shipping:
    pattern:  /politicasenvio
    defaults: { template: 'FrontendBundle:Site:shipping.html.twig' }

warranties:
    pattern:  /garantias
    defaults: { template: 'FrontendBundle:Site:warranties.html.twig' }

ml:
    pattern:  /ml
    defaults: { template: 'FrontendBundle:Site:forms.html.twig' }

Then at main routing.yml file I use the resource as:

_paginas:
    resource: routing_pages.yml
    prefix:   /
    defaults:
        _controller: FrameworkBundle:Template:template

I'm having some issues trying to access /app_dev.php|app.php route with this exception:

No route found for "GET /"

This is due to the configuration I have on access_control at security.yml:

access_control:
    #Security Login/Register/Resetting
    - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
    #Frontend Pages Routes
    - { path: ^/inicio, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/contact_one, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/horario, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/pagos, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/preguntas, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/preguntasb, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/politicasenvio, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/garantias, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/ml, role: IS_AUTHENTICATED_ANONYMOUSLY }
    #Login required
    - { path: ^/, role: ROLE_USER }
    - { path: ^/admin/, role: ROLE_ADMIN }

What I did like that? Because the stactic pages doesn't need login features just admin area does. I tried play with this two lines by changing to this:

    - { path: ^/, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/admin/, role: ROLE_ADMIN }

But then when I access `app_dev.php|app.php/admin I don't see the login form, why? How I fix that? Any advice?

If I could define /inicio as homepage in somewhere or somehow then the problem is fixed, tough, but I don't know how to.

You could just define a redirect from "/" to "/inicio" in the routing table:

# redirecting the root
root:
    path: /
    defaults:
        _controller: FrameworkBundle:Redirect:urlRedirect
        path: /inicio
        permanent: true
