firewall notifications

This tag collects WindowsForum.com discussion about firewall notifications in Windows 10 and Windows 11, focused on Microsoft Defender Firewall and the alerts it can raise when an application is blocked from accepting incoming network connections. The tagged content walks through enabling those alerts in the Windows Security app under Firewall & network protection, using Firewall notification settings and Manage notifications, and turning on the option to be notified when Microsoft Defender Firewall blocks a new app. It also covers checking the Domain, Private, and Public firewall boxes, plus configuring the same behavior through the classic Windows Defender Firewall Control Panel applet or related notification settings.
