https://msdn2.microsoft.com/en-US/library/ms177440.aspx How to: Configure a Server to Listen on a Specific TCP Port (SQL Server Configuration Manager) If enabled, the default instance of the Microsoft SQL Server Database Engine listens on TCP port 1433. Named instances of the SQL Server Database Engine and SQL Server Mobile are configured for dynamic ports, which means they select an available port when the SQL Server service is started. When connecting to a named instance through a firewall, configure the Database Engine to listen on a specific port, so that the appropriate port can be opened in the firewall. To assign a TCP/IP port number to the SQL Server Database Engine In SQL Server Configuration Manager, in the console pane, expand SQL Server 2005 Network Configuration, expand Protocols for <instance name>, and then double-click TCP/IP. In the TCP/IP Properties dialog box, on the IP Addresses tab, several IP addresses appear, in the format IP1, IP2, up to IPAll. One of these are for the IP address of the loopback adapter, 127.0.0.1. Additional IP addresses appear for each IP Address on the computer. Right-click each address, and then click Properties to identify the IP address that you wish to configure.If the TCP Dynamic Ports dialog box contains 0, indicating the Database Engine is listening on dynamic ports, delete the 0. In the IPn Properties area box, in the TCP Port box, type the port number you wish this IP address to listen on, and then click OK. In the console pane, click SQL Server 2005 Services. In the details pane, right-click SQL Server (<instance name>) and then click restart, to stop and restart SQL Server. After you have configured SQL Server to listen on a specific port there are three ways to connect to a specific port with a client application:

If you are using a different firewall system, see your firewall documentation for more information. If you are running a firewall on the computer that is running SQL Server 2005, external connections to SQL Server 2005 will be blocked unless SQL Server 2005 and the SQL Server Browser service can communicate through the firewall. You must create an exception for each instance of SQL Server 2005 that you want to accept remote connections and an exception for the SQL Server Browser service. SQL Server 2005 uses an instance ID as part of the path when you install its program files. To create an exception for each instance of SQL Server, you must identify the correct instance ID. To obtain an instance ID, follow these steps:
