change wp-admin folder
- The below code will prevent browser access to any file in these directories other than "a.b.c.d" which you should change to be your static IP address.
-
order deny,allowallow from a.b.c.d # This is your static IPdeny from all- OR restrict the directory with a password:
-
AuthUserFile /etc/httpd/htpasswdAuthType BasicAuthName "restricted"Order Deny,AllowDeny from allRequire valid-userSatisfy anyOr you can protect it with a .htaccess filehttp://www.askapache.com/wordpress/htaccess-password-protect.html
To answer you question as a apache URL layout configuration via mod_rewrite (the apache module that handles URL rewriting), this could be helpful:
RewriteRule ^admin/(.*)$ /wp-admin/$1 [QSA,L]
I use the following in my .htaccess file in the wp-admin folder:
order deny,allowallow from 12.34.56.78 # My IPdeny from allIt will give a 404 error to anyone not on that IP address.
I also use the same for the wp-login.php page. Put this in your root .htaccess file:
<Files "wp-login.php">Order deny,allowDeny from allAllow from 12.34.56.78</Files>
