You can use SetEnvIf and Allow:
<Location "/only_proxy/">
SetEnvIf X-Forwarded-For ^10\.1\.1\. proxy_env
Order allow,deny
Satisfy Any
Allow from env=proxy_env
</Location>

It's also reasonably easy to protect yourself from forged X-Forwarded-For headers (by stripping this header at entry points into your environment).– larsksOct 2, 2012 at 1:52

You can write a rewrite rule to redirect to 403 response.
RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-For} !(1.1.1.1|2.2.2.2)
RewriteRule .* - [F]
You can use mod_rpaf to make Apache treat the X-Forwarded-For IP as the client IP.

8For those who find their way here from Google: note that
mod_rpafis only able to make your logs useful; it does not actually affect the address used in access control decisions. Also note that in Apache 2.4, themod_rpaffunctionality is provided natively by mod_remoteip.– larsksOct 2, 2012 at 1:50 -
