I am trying to configure Nat Loopback for my Deco device, and can't seem to find it anywhere in the app

I see elsewhere on the forum that its stated regularly that this IS possible. How can it be done?

To be specific here, I am not looking for simple NAT forwarding. I can easily redirect external calls to my IP to a given device:port in my network

My goal is to redirect INTERNAL calls

For instance, I want to redirect router:443 to a given device:port on my network

Thanks!
