ASUS RT-AC66U B1 Nat loopback

Star I

Can anyone tell me, if it's possible to use NAT loopback on the ASUS RT-AC66U B1?
If not, can anyone tell me if ANY of ASUS' routers support it?

This is a thread regarding concern that later BIOS removed support for NAT loopback/hairpinning:

No NAT Loopback on RT-AC68U running 386.5.2 | SNBForums

It is over a year old now so I'm not sure things have changed to not support it, but it seems supported by default.  Please note posts 4 and 5 were very interesting/informative to me, as I have never heard of this prior, and had to do quite a bit of research.  On a precursory search through a couple of settings pages on my GT-AXE16000 I did not see any option to enable/disable NAT loopback/hairpinning...

It seems like they have disabled it in a firmware update at some point, because it doesn't work.
But thanks for the reply.
