    If the port is not managed, it is not opened from firewalla. If you are running FWG in router mode, then likely you do not have a public IP, the open port scan just scanned a shared ISP IP. see https://help.firewalla.com/hc/en-us/articles/360055686674-How-to-see-if-you-have-a-public-IP-address-

    Hello, thanks. It is a public IP. The IP for the WAN matches the same at WhatsMyIP.

    I'm not following the logic that it's not opened from Firewalla. It's a very simple setup: Internet -> ISP -> Cable Modem -> Firewalla Gold -> Internal Network.

    As it is a public IP, the ISP is a pass-through. How could it not be the Firewalla? The IP that was scanned was the same IP as shown on the WAN interface as well; I used a third-party to validate what the FWG reported.

    When I do a netstat it is showing that the port is open on my local network, and curiously the WAN interface's address as well...for both UDP and TCP.

    This is making me a bit nervous now. What am I not seeing that is potentially exposing more than it should?
