Configure SQL server to listen on a specific port
How to configure the SQL server to listen on a specific port?
Owing to security issues it is often not recommended to use the default port number 1433 for communicating with the SQL server. This article helps set up the SQL server to use a non-standard port number.
- Run the SQL Server Configuration Manager.
- Select the SQL Server Network Configuration.
- Select from the list the instance you want to configure to listen to on a specific port.
- To change the port assignment right-click on the TCP/IP protocol and select Properties.
- Click on the IP Addresses tab.
- Specify the port number you want to use instead of 1433 by entering the preferred port number. Also, turn off the dynamical port number setting by removing the “0” mark in the TCP Dynamic Ports field.
- In order to finish the adjustment, select SQL Server Services, click on SQL Server and restart it.
