Can Big IP 3600 do Nat Overlapping?

I think that will do it, now I just need to research it further for setup and configuration. This would be functional isolation, traffic would flow in and our but hostname and IP would not.

 

 

We have a complex configuration currently deployed behind a 3600 Big IP and no other Layer 3 devices to work with. The hostname and IP at times are deeply embedded in the configuration, so changing IP or hostname can cause failures

 

 

So functional Isolation or NAT is the only way......
