turn console off, disable upnp in xr500 menu and apply then power off XR500 and unplug from power for 2 minutes. Then, plug the power back into XR500 and reboot. Wait 2 minutes and re-enable upnp and apply then reboot console and you should have open nat.
Try this step and if this does not work I shall send you a port forwarding guide.
