1) Yes I had OPEN NAT with this provider before which is SPECTRUM.
2) Right now I'm connected to the modem itself, ran the test and so far it came back with only one line with a response, the rest keep saying ''REQUEST TIMED OUT'', so if I'm not mistaken based on that, I don't have CG-NAT right??
3) I do have my PC with a static IP set in the XR500 and UPPnP is enabled.
4) Any other suggestion to get OPEN NAT??
