Apologies, but this subject keeps cropping up and most of the posts I have come across are now too old so I will ask again. I want to log the originating client IP address in the postclientflow of my API proxy. There are a number of things that I need clarification on.
1. If I log 'client.ip' value, this always seems to contain an address from the internal IP range (e.g
192.168.81.85). Where is this being populated?
2. If I set the 'X-Forwarded-For' header to some value, then this gets populated into the 'client.ip' and will be logged with one exception - if a node.js target is called, the client.ip address again contains an internal IP address.
This is a bit problematic since at the moment, the 'X-Forwarded-For' header can to set to any value and the edge platform will accept it and use it (it seems). It also appears, the original X-Forwarded-For value is then thrown away if a node.js target is called.
How is it possible to reliably log the originating Client IP address?
