Symfony 2 Securing Login with IP

问题:

I have a firewall rule which together with annotations allows only access to actions as specific user.

Additionally I would love to block ANY login if it is not coming from a certain network. Searching for a solution I came across additional access_control rules following this guide.

The problem there is, if I restrict my login page via IP rules. I always get an ERR_TOO_MANY_REDIRECTSerror if someone tries to reach it. I would rather love to have a "Page not Found" message to not even make someone from outside aware there could be any login.

How can I do this with Symfony?

security.yml:

security:
    ...

    firewalls:
        dev:
            pattern:  ^/(_(profiler|wdt)|css|images|js)/
            security: false

        default:
            form_login:
                provider: fos_userbundle
                login_path: /login
                use_forward: false
            logout:       true
            anonymous:    true

    access_control:
        - { path: ^/logout$, role: ROLE_ADMIN }
        - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY, requires_channel: https, ips: [127.0.0.1, fe80::1, ::1]}
        - { path: ^/login$, roles: ROLE_NO_ACCESS }
        - { path: ^/admin, role: ROLE_ADMIN, requires_channel: https}

回答1:

If I am not mistaken, what Symfony does here, is try and match the role of the user to what is required for the path. If it doesn't match one of those roles, it sends the user to the login page.

The problem is, the login page is where the user has just come from. Thus the user gets into an infinite loop as their condition can never be met.

I would suggest putting the login page itself outside of the firewall and just put the IP check within the code of the LOGIN page and if not met, dump out somewhere else, which isn't within the firewall.
