RBR750 Local NAT Loopback Not Working
I am having issues with NAT Loopback not working with my RBR750 when accessing a resource on my local LAN. I've reviewed this thread (Orbi NAT Hairpinning/Loopback Not Working - NETGEAR Communities)...
Do you have any RBS? If so, what model RBS do you have?
Has this worked for you at all in this configuration? Or is this the first time setting this up?
Have you tried the ISP modem in router mode and the RBR in AP mode to see if loopback works at the modem?
Totally "my bad" about the 350.
Is DDNS set up
- On the Synology, or
- On the Orbi router?
I find the documentation about Synology Quick Connect confusing. Specifically, the comment that Quick Connect "works better" if ports 5000, 5001, and 6690 are forwarded through the customer router.

What the heck? Does Quick Connect function through port forwarding or is it like so many Internet of Things connections (using an IP connection established by the Synology connecting to a Cloud service)?
DDNS is configured on the Synology.
Quickconnect appears to punch a whole like other IOT devices. Because Synology serves as a proxy for this service, I typically keep it turned off for security. However, I've enabled it to try to assist with troubleshooting this more general DDNS resolution and routing issue.
