    Click Open

    Select Port
    Click Next
  4. Protocol and Ports
    Select TCP
    Select Specific local ports: #### (Choose a number you like for your port)
    Click Next
    NOTE: If you are enabling a remote connection to SQL, then enter 1433 as the port number
  5. Select Allow Connection
    Click Next
  6. Click Next
  7. Give the port a name __MSSQL (We recommend using two underlines at the start of the name to make it stand out)
