Apache allow access by IP range OR HTTP referrer

Hi experts,

I have a requirement to block all web traffic to a site EXCEPT from a certain IP range, plus from my static IP address. I also need to use an uptime monitoring service. The service I am using does not have static IPs and the only distinguishing factor is the referer url.

How can I create rules to satisfy these requirements on Apache (eg in .htaccess)

I figured it out. See below

1. Ignore all where http referer is from example.com
2. Ignore all from ip range
3. Ignore all from ip
4. Forbid everyone else

  RewriteCond %{HTTP_REFERER} !^http://example\.com/.* [NC]
  RewriteCond %{REMOTE_ADDR} !^192\.168\.0\.[1-255]$
  RewriteCond %{REMOTE_ADDR} !^127\.0\.0\.1$
  RewriteRule ^(.*)$ /$1 [L,R=403]

Hi,

What you are looking for is the HTTP_REFERER and REMOTE_ADDR Conditional statements. Here is an example .htaccess file you could use in the directory you want to restrict.

.htaccess
------------
RewriteEngine on
RewriteBase /

#If  incoming URL is http://www.yourreferralurl.com. This is just and example
  RewriteCond %{HTTP_REFERER} !^http://www\.yourreferralurl\.com/ [NC]

#If IP is 192.***.***.*** This is just and example
  RewriteCond %{REMOTE_ADDR} ^192\.([0-9][0-1][4-9])\.  
  RewriteRule ^.*$ - [F]
------------
