nice but not perfect

You can customize the basic behavior of this plugin. Put the following code into functions.php of your theme.

function my_whitelist( $validate ) {
    $whitelist = array(
        'NL',
    );

    $validate['result'] = 'blocked';

    foreach ( $whitelist as $country ) {
        if ( $country === $validate['code'] ) {
            $validate['result'] = 'passed';
            break;
        }
    }

    return $validate;
}
add_filter( 'ip-geo-block-login', 'my_whitelist' );
add_filter( 'ip-geo-block-admin', 'my_whitelist' );

Try it or open your issue at forum. I’m glad to help you.
