My apache access log shows a normal public ip address, but Piwik is showing me a private 10.95.x.x address in the web interface for the same visit.
Is Piwik showing me the user's external non-NATted address, or is it doing too many forward and reverse lookups? I have no idea.
This is a duplicate of #567.
Piwik uses the client's forwarded IP address instead of the proxy's IP address.
