access_restriction.prefer_cf_connecting_ip

Determines if the IP address passed via the Cloudflare CF-Connecting-IP header should be used for checking access restrictions.

Set this configuration key in the results page (preferred) or search package configuration.

Use the configuration key editor to add or edit the access_restriction.prefer_cf_connecting_ip key, and set the value. This can be set to any valid Boolean value.

If search requests for your results page are received via CloudFlare then CF-Connecting-IP contains the original IP of the browser, and it is that header if present which is used for access restriction
