    Windows Defender Firewall + Windows FTP Server

    Why is windows defender firewall disobeying my firewall rules?

    • Enabled Windows FTP Servers via Windows 10 Features.
    • Rules are in the firewall allowing FTP access for both passive & control (rules were injected through enabling the service).
    • FTP packets are dropped by the firewall still (confirmed in the logs) but no rule is given, just "DROP".
    • This is over a VPN that is being detected as "Unidentified Network" thus putting the interfaces in the "Public" zone.
    • FTP rules apply to all three zones (Public, Private, and Domain).
    • Turning off Windows Defender Firewall for the specific zone allows the FTP transaction.
    • There are no rules denying this traffic in the list.

    How to configure router firewall to allow Windows Defender to update virus definition?

    Windows 10 version 1607 and 1703. My firewall is Fortigate 60E.

    To configure firewall policy to allow Windows Defender to update virus definition, I need the following information:

    1. List of URLs / domain names / IP addresses used by the update server.

    2. Port numbers used by Windows Defender to check and download updates.
