Hi. You have 2 options: First you may disable the sorce nat on your load balancing device. Second you need to enable the x-forwarder-for option, you are just "preparing" the log to get that information, now you need to send it to the squids log. I hope this helps. Saludos Ing.

So i can see only the loadbalancer IP as a source IP in the squid logs. I have configured the log format with %{X-Forwarded-For}>h . But in this field shows "-" . Not showing original client IP. How to configure the squid to find the original client IP in squid logs ? Thanks, Sekar
