 Restricted Site Access is not meant to be a top secret data safe, but simply a reliable and convenient way to handle unwanted visitors.
 
-In 7.3.2, two new filters have been added that can be utilized to help prevent IP spoofing attacks. The first filter allows you to set up a list of approved proxy IP addresses and the second allows you to set up a list of approved HTTP headers. By default, these filters will not change existing behavior. It is recommended to review these filters and utilize them appropriately for your site to secure things further.

-		 *
-		 * Use this hook to modify the permitted proxy headers. For sites without a

+		 * By default we only trust the REMOTE_ADDR header, as other
+		 * headers can easily be spoofed.

-		 * - HTTP_CF_CONNECTING_IP
-		 * - HTTP_CLIENT_IP
-		 * - HTTP_X_FORWARDED_FOR
-		 * - HTTP_X_FORWARDED
-		 * - HTTP_X_CLUSTER_CLIENT_IP

-		 * - HTTP_FORWARDED
+		 * If your site is behind a proxy, typically the REMOTE_ADDR header

+		 * deal with this situation, you'll need to use this filter
+		 * to set any other headers you want to trust.
 		 *
-		 * To allow for CDNs, these headers take priority over the REMOTE_ADDR value.
+		 * Note that by doing this you will open your site up to IP spoofing
+		 * attacks so proceed with caution. If possible, you should also use
