-The last change that I make is to add the hostname I will use for this instance to an authorized hosts array in the web interface php file. I do this so that when I try and access my instance from the friendly name I have set up in DNS or a reverse proxy, I don't have to remember the /admin suffix. To do this, you will need to edit the index.php file of Pi-hole.
+### Redirect to Admin
+
+The last change that I make is to redirect HTTP requests to the root path to the pihole `/admin` path. I find it annoying this isn't done by default but it's an easy fix. Simply add the following line to the `lighttpd.conf` file.
 
 ```bash
-sudo nano /var/www/html/pihole/index.php
+sudo nano /etc/lighttpd/lighttpd.conf
 ```
 
-In this file I edit the authorizedHosts array
-
-```php
-$authorizedHosts = [ "localhost", "pihole.local" ];
+```conf
+url.redirect = ("^/$" => "/admin" )
 ```
 
-> index.php is likely overwritten whenever Pi-hole is updated and these changes will need to be reapplied

 ## High Availability with keepalived
 
 To have a high availabilty cluster, you will need more than one Pi-hole instance running. Once you have them both running, you can configure `keepalived` to set up a virtual IP between them using a technology called VRRP. It allows both servers to share a virtual IP between them, swapping instantly when one of them goes down. Because this is more of a "hot spare" methodology, one node will be primary, and the rest will be secondary. To get started you will need to install two pacakges.
