RBR850 / RBK852 Unable to disable WEBGUI access from public network

[Ryan4332]

Netgear has removed the remote management a few version ago. I am 100% sure that the remote management check box is unchecked before I made the firmware upgrade. I also made a hard reset after the upgrade. But the WEBGUI still able to access using the public ip and the netgear DDNS Domain name using http(port 80) / https(port 443). The router using port 80 to host its WEBGUI, if checked the Always Use HTTPS to Access Router under Web Services Management will make the WEBGUI hosted on both port 80 and 443 and redirect to 443 after the login prompt.

Firmware Version: V4.6.8.2_2.1.9

Router Model: RBK852

Fibre ONU with bridge mode and router Internet IP Address is DHCP
