Nagios 403 forbidden, indexes

I installed nagios under freebsd 9, but can't figure out the right way for it to be public in the browser (from other pc's). I think that the problem is in the indexes or that there is no index file (other than main.php). Apache says that syntax is ok. The permissions of the dir are 777. The logs say:

Directory index forbidden by Options directive: /usr/local/www/nagios/.

This is my configuration:

ScriptAlias /nagios/cgi-bin/ /usr/local/www/nagios/cgi-bin/
Alias /nagios /usr/local/www/nagios/

<Directory /usr/local/www/nagios>    
    Options +Indexes FollowSymLinks +ExecCGI
    AllowOverride Indexes AuthConfig FileInfo
    Order allow,deny
    Allow from all
    AuthName "Nagios Access"
    AuthType Basic
    AuthUSerFile /usr/local/etc/nagios/htpasswd.users
    Require valid-user
</Directory>

<Directory /usr/local/www/nagios/cgi-bin>    
    Options +ExecCGI
    AllowOverride None
    Order allow,deny
    Allow from all
    AuthName "Nagios Access"
    AuthType Basic
    AuthUSerFile /usr/local/etc/nagios/htpasswd.users
    Require valid-user
</Directory>

I think that the problem is in indexes, maybe? When I remove the options it's public and available but lists the files and says that indexes are forbidden.
