The HTTP/HTTPS ports won't be configured in the Settings>Bindings area unfortunately Patrick. I see kestrel has bound to 0.0.0.0:80, but I wonder if we might need an additional binding for all IPv6 interfaces. I'm going to check in with development on this for you and I'll follow up when I know more.
