Answer 1

Haven't specifically done this yet but something similar

In the theme page/post template files you can get post id of current post/page by doing

$currentID = get_the_ID();

Then redirect all traffic not from the specified IPs

$ipArr = array('xx.xxx.xxx.xxx', 'xx.xxx.xxx.xxx');

 if (!in_array(@$_SERVER['REMOTE_ADDR'], $ipArr))
{
    header("Location: http://example.com/myhomepage");
    die();
}

You can block the access page for all IPs, but a whitelist.

function page_ip_restriction() {
    if(is_page('yourpage'))
    {
        // Whitelist
        $whitelist = array(
            '127.0.0.1',
            '127.0.0.2',
            '127.0.0.3',
        );

        // Check if current user IP is out of the whitelist, then redirect to home
        if(!in_array($_SERVER['REMOTE_ADDR'], $whitelist))
        {
            wp_redirect(home_url(), 403); // 403 -> Forbiden access
            exit();
        }
    }
}
add_action('init', 'page_ip_restriction', 10);

For your submenu, you have two ways, the wordpress one, or a css exclusion. But IMO, WordPress menus are really heavy to use.

If you want better IP address tracking, use a librairy.

Hope it's help you !
