SQL Server Port


The SQL Server port is 1433.

The client application port that connects to SQL Server is usually a random port between 1024 and 5000. This port on the client computer is what port SQL Server will use to send data back to the client with.

Firewall Considerations
If you are looking to setup a firewall to work with SQL Server ports, you will need to make the following settings:

  • Allow traffic from any port greater than 1024 to port 1433
  • Allow traffic from port 1433 to any port greater than 1024
