As Zuke has implied, I think you're expecting the X-Forward-For option to pass the client IP to the server in the TCP packet. That's not what this option does. It and the iRule are intended to insert an HTTP header into the HTTP request flowing to the server. It does not change the source address of the packet.

 

You're seeing the F5 (floating) source address because you have SNAT enabled.
