MW IP Denied allows you to set access restrictions by IP address for each article. When access is restricted and there is template-access-denied.php, MW IP Denied load it.
You can also use short code for controlling the access on a part of the article.
Only the IP address that you specify can access. [mw-ip-allow allow=”IPAddress,…”]text[/mw-ip-allow]
Only the IP address that you specify can not access. [mw-ip-deny deny=”IPAddress,…”]text[/mw-ip-deny]
