This script is only accessible from localhost - apache

Question

I have a working project with Symfony2.
One of my bundles works well by default but when I activate mod_rewrite I get
This script is only accessible from localhost
This happens only with the routes configured on this bundle, others work fine with mod_rewrite
Here is my vhost config
<VirtualHost *:80>
ServerName my_application.my_domain.net
ServerAdmin xxx#xxx.xxx
DocumentRoot "/var/www/my_application/web"
<Directory /var/www/my_application/web/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
Allow from All
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /app.php [QSA,L]
</IfModule>
</Directory>
</VirtualHost>
Where can that come from ?
Update
Example
I'm getting the error when trying to access
my_application.my_domain.net/config/list/produit
If I disable mod_rewrite I can access
my_application.my_domain.net/app.php/config/list/produit

Answer 1

Are you hitting app_dev.php or config.php?
By default, both of those restrict connections from anywhere but localhost and display that exact same message.
Update
After the update, I think the problem may be because you have MultiViews enabled. MultiViews can try to load config.php even if it is just referenced as config. Try removing that and see if it helps improve anything.
