  • You will see all the firewall port rules for incoming connections. On right side, click on New Rule link to start adding new rule for opening port in firewall.

  • Now you will have wizard to help you add port opening rule. Since we are going to open port, select radio button for Port. For example for SQL Server you will enter port number as 1433 if you have default settings for SQL Server.
