            array('allow',
            'actions' => array('index','view', 'create', 'update', 'manage'),
            'ips' => Yii::app()->params['allowIps'],//updated to pull list from Yii
           ),
            array('deny',
                'actions' => array('index','view', 'create', 'update', 'manage'),
                'ips' => array('*'),
            ),
        );
    }

in /protected/config/main.php

    'params'=>array(
            // this is used in contact page
            'allowedIps'=>array('22.150.133.177'),
    ),

Answer 1

The other answer will only work during a given session and then the blacklist will revert.

I would suggest you use a Security component (that you write) that stores the appropriate information in a database (or some other system that allows you to change it). Then, either have the security component modify the params array or better yet modify your system to retrieve the info directly from the component.

For adding new IP

array_push(Yii::app()->params['allowIps'],'4.4.4.4');

For Removing IP

if (($key = array_search('4.4.4.4', Yii::app()->params['allowIps'])) !== false) {
    unset(Yii::app()->params['allowIps'][$key]);
}
