Thank you Ed for responding to my request. Firewall tech support mentioned that the loopback option is not available with current firmware. They suggested to upgrade. I'm currently in the process to upgrade to latest firmware. Will report back soon.

Hi Kris, How about your question? Any updates?Frank Wang

Sorry Frank. Yes, I have uploaded NEW firmware OS to support loopback and it works. Thanks
