Debugging behind AWS load balancer?

Anybody got solution how to enable Robust Exception Info on ColdFusion Server 9.01 running behind a load balancer on AWS?

One option is to disable the HTTP status codes but we do need the functionality.

Please note that everything is working without the load balancer and the Robust Exception is enabled and we added our IP to the Debugging IP Addresses section.

We have even added ISAPI Xforwarding functionality and we do see the correct IP in logs but CF Admin is still ignoring those headers.

Thanks

Edit: The same will apply to websites that are NOT behind load balancer as AWS is forwarding everything to a private IP so this issue is not just a load balancer.
