$front->setParam('useDefaultControllerAlways', true); ?
No to set the default controller you use
$front->setDefaultControllerName('index')In you your "bootstrapper" (before your call $front->dispatch())
However the above should not be necessary, as zend should call the index controller (or action) by default if its not specified in the url. To test go to mysite.com, and Zend should call the indexAction within the indexController automatically without you specifying it in the url.
