Configure Windows Firewall

There are two methods for configuring Windows Firewall for SQL Server.

Choose one of the two methods below, that best suits your IT policy:

Create Inbound Rules for the SQL Server Ports
Allow the SQL Server applications in the Firewall

Create Inbound Rules for the SQL Server Ports

This method will target the specific ports SQL Server uses for communication.

Open Windows Control Panel and select System and Security.
From the System and Security window, click Windows Defender Firewall.
From the Windows Defender Firewall window, click Advanced Settings.
Add the port SQL uses for TCP.
From the Windows Defender Firewall with Advanced Security window:
Select Inbound Rules from the left hand column.
Click New Rule... from the Actions column.
From the New Inbound Rule Wizard, select Port.
Click Next.
Select TCP.
Select Specific local ports.
Enter 1433.
Click Next.
Select Allow the connection.
Click Next.
Select Domain, Private and Public.
Click Next.
Enter a name for the rule.
For example: SQL TCP.
Add the port SQL uses for UDP.
From the Windows Defender Firewall with Advanced Security window:
Select Inbound Rules from the left hand column.
Click New Rule... from the Actions column.
From the New Inbound Rule Wizard, select Port.
Click Next.
Select UDP.
Select Specific local ports.
Enter 1434.
Click Next.
Select Allow the connection.
Click Next.
Select Domain, Private and Public.
Click Next.
Enter a name for the rule.
For example: SQL TCP.
Click Finish.

Allow the SQL Server applications in the Firewall

This method will open all ports for access to SQL Server.

Open Windows Control Panel and select System and Security.
From the System and Security window, click the link to Allow an app through Windows Firewall.
Allow the SQL Server Browser:
Click the Allow another app... button.
If your Windows Firewall settings are managed by your system administrator, you may need to click the Change Settings button.
Click the Browse button.
Browse to sqlbrowser.exe
This is located in the default installation folder:
C:\Program Files (x86)\Microsoft SQL Server\90\Shared
Click the Add button.
Allow the SQL Server Application:
Click the Allow another app... button.
Click the Browse button.
Browse to sqlserver.exe
This is located in the default installation folder:
C:\Program Files\Microsoft SQL Server\<Version and Edition>\MSSQL\Binn
Version and Edition
The Version and Edition folder depends on the installed SQL Server.
For instance:
- SQL Server 2012 (Express) is located within the folder MSSQL11.SQLEXPRESS
- SQL Server 2017 (Express) is located within the folder MSSQL14.SQLEXPRESS
Other versions and editions will be similarly named and cannot be confused with the other folders in the Microsoft SQL Server folder.
Click the Add button.
Click the OK button to save and apply the changes.
