Why would you send the client a 302? I'm a bit confused about the relationship between the 302, least connections algorithm and NAT problems.

 

Least connections can be selected as your default pool's algorithm.

 

As for NAT problems and X-Forwarded-For, you need to apply source NAT to your Virtual Server and use X-Forwarded-For to send the true client IP to your pool members if said pool members do not use the Big IP as default gateway. Otherwise you will end up with assymetrical routing and it will most likely break your application.
