RBR50 - how to configure NAT loopback?

I have an RBR50 (firmware 2.7.5.4), and according to this KB article, it supports NAT loopback. However, I cannot find anywhere in my Oribi's settings to configure it. Does anyone know how to set NAT...

The feature cannot be configured.  It simply works.

Notice in the Wikipedia description that for NAT Loopback to be successful, the target port must be forwarded through the switch to a device on the LAN.  Port forwarding is on the Orbi web interface, Advanced Tab, Advanced Settings (bottom menu item).

    Hello TokyoHam ,

     

    Welcome to the NETGEAR Community!

     

    NAT loopback is a feature that allows the access of a service via the WAN IP address from within your local network. NAT loopback is useful If you require internal users to access an internal service such as a hosted web server using the public IP address instead of its local IP address. The RBR50v1 and RBR50v2 support NAT loopback as a feature. Configuration is not needed.

     

    For all of our devices that support NAT Loopback please visit our Knowledge Based article below:

    Best,

      Thank you for the replies.

      I guess I was thinking of something more along the lines of a host file, where I could manually specify [domain1.com --> 192.168.1.50] but from what I understand, it only works when the WAN address of the Orbi matches the server address. Unfortunately, my Orbi sits behind a router provided by my ISP (I know, I know - but there's literally nothing I can do about it), so the Orbi doesn't know what the public-facing IP address is. If Netgear hadn't removed Telnet access, I could simply SSH in and manually edit the hosts file - maybe it's worth installing third-party firmware to restore the functionality that my Orbi system had when I bought it.
