how to capture client ip when having a proxy between LB and PIA

Hi,

We have this infrastructure setup

Load balance  server -> Apache server with Weblogic plugin -> PeopleSoft webserver

According to note 1375129.1, this Apache server won't pass on header WL-Proxy-Client-IP.

I tried to overide the client IP header in weblogic console.

Environment -> Servers -> PIA -> Protocols  -> HTTP

Remote Address Override: X-Forwarded-For

But the app server log appsrv.log and table psaccesslog still show load balance server IP.

So with our infracture setup, how can we capture real client IP in PeopleSoft?

thanks
