XR500 Port Forwarding
Howdy! I am stumped after being at this most of a week. I am trying to open a couple ports through my Nighthawk XR500 V2.3.2.134 running DumaOS. When I use the grc Shield's Up scanner, it shows all (every one) of my ports as 'Stealth' even though I've 'opened' in the router. For context without specifics I have a Mac mini running macOS 14.5 ethernet connected to the XR500. I assigned the Mac a static IP. In Port Forwarding of the router, I added custom service both udp/tcp on port xxxxx for that IP. I've rebooted everything in sequence. Yesterday I spoke with Spectrum to ask about a double NAT issue (I only have a modem from them not a combo) and they said I'd have to reach out to the router community. Any thoughts?
I've managed to use my service if I'm running behind a VPN with port forwarding but I can't get anything if I don't run the VPN and I'd rather not have the VPN in front of the service.
Any help would be greatly appreciated!
It's either or. uPnP works in most configurations. Specialized configurations, needs to be disabled.

Just to add some information/confusion. Attached images. Port showing open in my test application though on canyouseeme it's error closed and on grc it's stealth. Also router view for port forward on internal IP.
- Quick update - did a bunch of troubleshooting today with some techies’ help. Things learned - I’m not behind CG NAT/double NAT. The problem appears to be with the XR500. Some zone/security/something or other is not allowing the opening of ports on my network. Please help if you can!
Is uPnP disabled if you have any PF configurations setup?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
- UPnP is currently enabled and attached to a different service & port from what I’m working on currently. Modem picture attached.
