.htaccess no longer denying pages to non specified IP addresses

I haven't head back from my network guys yet.

 

 

I did find this at http://www.it.emory.edu/showdoc.cfm?docid=11252&fr=1092

 

Apache Notes

 

 

Because of a quirk of our load balancer configuration, all incoming requests seem to come from the load balancer's IP address. If you want to restrict access to content based on source IP address in a .htaccess file, something like this will not work:

 

 

deny from all

 

allow from 170.140.0.0/16 163.246.0.0/16

 

 

Instead, use mod_rewrite to inspect the X-Forwarded-For header:

 

 

RewriteEngine on

 

RewriteCond %{HTTP:X-Forwarded-For} "!(170\.140|163\.246)\.[0-9]{1,3}\.[0-9]{1,3}$"

 

RewriteRule .* - [F]

 

 

 

But I can't get it to work when I change the condition to my IPs, just blocks everything.
