If the request includes the 'X-Forwarded-For' header, then the patch will
use the value in that header for acls, if it doesn't (i.e. direct client
access, or a proxy/loadbalancer that's configured not to include this
header) then the actual connecting IP address will be used.

You can't find the original IP address if it's not included in the request
headers.
