Limit AdminCP to one IP Address
 

Is there anything in the AdminCP which will be effected like maybe RSS Feeds etc, or anything else that will have an adverse effect if I drop a .htaccess file in the AdminCP directory limiting access to that folder from just one IP Address only using this below. Off course, if Mods in the future needs access to that same folder also, more IP's can be added later to the list.

I'm just wondering though, if any outside sources still need access to the AdminCP folder for any reason, and doing this will just create problems that I'm overlooking.

Code:
order deny,allow
deny from all
allow from xxx.xxx.xxx.xx
Better still though, does anybody know (using .htaccess) how I can just limit one file (index.php) (Admin Login) in the AdminCP folder, to just one IP only. So all other files can be accessed by anybody, but the AdminCP login-screen limits access to just one IP Address. I've tried using the directive, but it's not working like this below.

Code:


order deny,allow
deny from all
allow from xxx.xxx.xxx.xx
