| Learn how to check Windows 11 Firewall settings, verify firewall status, allow apps, and troubleshoot network connection problems. |
Windows 11 Firewall is an important security feature that helps protect your computer from unauthorized network connections. It monitors network traffic and can allow or block connections based on network profiles, applications, ports, and firewall rules.
If an application cannot connect to the internet, another computer cannot access a shared resource, or a network feature suddenly stops working, checking the firewall settings can help determine whether Windows Firewall is involved.
In this guide, you will learn how to check Windows 11 Firewall settings using Windows Security, Control Panel, PowerShell, and advanced firewall tools. You will also learn how to check allowed apps, network profiles, firewall status, and common settings that can affect network connections.
What Is Windows 11 Firewall?
Windows Firewall is a security feature included with Windows 11. It helps filter network traffic and block unauthorized connections while allowing legitimate network communication.
Windows Security provides a central interface for viewing and managing firewall protection. From there, you can check the firewall status for different network profiles, access allowed-app settings, open advanced firewall configuration, and restore firewall settings when necessary.
Windows 11 can use different network profiles, including Private, Public, and, on managed systems, Domain. The firewall can apply different behavior depending on the profile currently being used.
Why Check Windows 11 Firewall Settings?
Checking your firewall configuration can be useful when troubleshooting problems such as:
- An application cannot connect to the internet.
- A local network application cannot communicate with another computer.
- File or printer sharing does not work correctly.
- A network service appears to be blocked.
- You want to verify that Microsoft Defender Firewall is enabled.
- You need to determine which network profile is currently protected.
- You want to review applications that are allowed through the firewall.
- You suspect a firewall rule is interfering with a connection.
However, firewall settings should be changed carefully. Microsoft notes that turning off Windows Firewall can make a device more vulnerable to unauthorized access. If a particular application is being blocked, allowing the application through the firewall is generally preferable to disabling the firewall completely.
How to Check Windows 11 Firewall Settings in Windows Security
The easiest way to check the firewall status in Windows 11 is through the Windows Security app.
Step 1: Open Windows Security
- Click Start.
- Type Windows Security.
- Open the Windows Security app.
Step 2: Open Firewall & Network Protection
- In Windows Security, select Firewall & network protection.
- Windows Security will display the available network profiles.
- Select the network profile you want to inspect.
Depending on the computer and network environment, you may see profiles such as Domain network, Private network, and Public network.
Step 3: Check Microsoft Defender Firewall Status
After selecting a network profile, look for Microsoft Defender Firewall.
If the firewall is enabled, Windows displays that the firewall is active for that network profile. If it is disabled, Windows Security provides an option to turn it back on.
Microsoft recommends keeping the firewall enabled. If an application is being blocked, you can investigate the application's firewall permissions instead of simply turning off firewall protection.
How to Check Firewall Settings for Private and Public Networks
Windows 11 treats Private and Public networks differently because the level of trust can be different.
Private Network
A Private network is generally intended for a trusted environment such as a home or other network where you know the devices connected to it.
Private network settings are particularly relevant when using local network features such as file sharing, printer sharing, and Network Discovery.
If you recently configured file sharing, you can also review your network profile using our guide:

Public Network
A Public network is intended for networks where other connected devices may not be trusted, such as public Wi-Fi.
Windows applies stricter network protection behavior to help reduce the possibility of unwanted connections from other devices.
If a computer is incorrectly configured as a Public network when you are trying to use trusted local-network sharing, check the network profile before changing firewall settings.
How to Check Allowed Apps Through Windows Firewall
Windows Firewall allows specific applications to communicate through the firewall when the appropriate permission is configured.
Step 1: Open Allowed Apps
- Open Windows Security.
- Select Firewall & network protection.
- Select Allow an app through firewall.
- Select Change settings if the controls are locked.
Step 2: Review the Application List
You will see a list of applications and associated network permissions.
Review whether the application you are troubleshooting appears in the list and whether the appropriate network type is allowed.
For example, an application may be permitted on a Private network but not on a Public network.
Only allow applications that you recognize and trust. Microsoft specifically warns against allowing unknown applications to communicate through the firewall.
How to Check Windows Firewall Advanced Settings
Windows 11 also provides an advanced firewall management interface called Windows Defender Firewall with Advanced Security.
- Open Windows Security.
- Select Firewall & network protection.
- Select Advanced settings.
You can also search for Windows Defender Firewall with Advanced Security from the Start menu.
The advanced interface provides access to areas such as:
- Inbound Rules
- Outbound Rules
- Connection Security Rules
- Monitoring
Inbound rules control incoming network connections, while outbound rules can control network connections initiated by applications or services on the computer.
Advanced firewall rules should not be changed randomly. Incorrect rules can cause applications or network services to stop working and may weaken the security of the computer.
How to Check Windows 11 Firewall Status Using PowerShell
PowerShell provides a convenient way to inspect Windows Firewall profiles without navigating through the graphical interface.
Open Windows PowerShell or Windows Terminal, then run:
Get-NetFirewallProfileThe command displays information about the firewall profiles configured on the computer.
Look for the Enabled property to determine whether firewall protection is enabled for each profile.
You can also use the following command to display a simpler status summary:
Get-NetFirewallProfile | Select-Object Name, Enabled, DefaultInboundAction, DefaultOutboundActionThis can help you quickly review the firewall state and default inbound and outbound actions for each network profile.
How to Check Windows Firewall Status with Command Prompt
You can also check firewall status using Command Prompt.
- Open Command Prompt.
- Run the following command:
netsh advfirewall show allprofilesWindows will display firewall configuration information for the available profiles.
This method can be useful when troubleshooting a computer where Windows Security is difficult to access or when you need to quickly inspect firewall configuration from the command line.
How to Check Firewall Rules in Windows 11
If a specific application or network service is not working, you may need to inspect the firewall rules.
Open Windows Defender Firewall with Advanced Security and select Inbound Rules or Outbound Rules.
Review rules associated with the application or service you are troubleshooting.
Pay attention to the following information:
- Rule name
- Enabled status
- Action
- Program
- Protocol
- Local port
- Remote port
- Profile
A rule may apply only to a particular network profile, which is one reason checking the current network profile is important.
How to Check Whether Firewall Is Blocking File Sharing
Windows Firewall can affect local network sharing. If you recently configured shared folders or printers but another computer cannot connect, check the network profile and firewall configuration.
First, make sure the computers are connected to the same local network. Then check that Network Discovery and File and Printer Sharing are configured appropriately.
You can review the related settings in our guide:

Should You Turn Off Windows Firewall to Fix Network Problems?
Generally, turning off the firewall should not be the first troubleshooting step.
Microsoft warns that disabling Windows Firewall can make your computer more vulnerable to unauthorized access. If an application is blocked, a better approach is to determine whether the application should be allowed through the firewall.
For example, Microsoft distinguishes between allowing an application and opening a port. Opening a port can create a broader exposure because the port remains available until the rule is closed, while an allowed application can use the required network access when needed.
If you need to troubleshoot whether the firewall is related to a problem, investigate the relevant application, rule, network profile, and firewall logs rather than permanently leaving the firewall disabled.
How to Restore Windows Firewall to Default Settings
If firewall rules have been modified and you are no longer sure which settings were changed, Windows Security provides an option to restore firewall settings to their defaults.
- Open Windows Security.
- Select Firewall & network protection.
- Scroll to the firewall settings.
- Select the option to Restore firewalls to default.
- Confirm the action when prompted.
Be aware that restoring firewall settings can remove customized firewall rules. If the computer is managed by an organization, organizational policies may be reapplied after the reset.
Windows 11 Firewall Troubleshooting Checklist
If an application or network connection is not working correctly, use this checklist before changing advanced firewall rules:
- Confirm that Microsoft Defender Firewall is enabled.
- Check the current network profile.
- Determine whether the network is Private or Public.
- Check whether the application is allowed through the firewall.
- Review relevant inbound and outbound rules.
- Check Network Discovery if the problem involves local network devices.
