If you did not install SQL Server as default instance (if it is installed as named instance) do the following

1)In SQL Server Configuration Manager, expand SQL Server Network Configuration, expand Protocols for instance_name, and then double-click TCP/IP.

2)In the TCP/IP Properties dialog box, on the IP Addresses tab, several IP addresses appear in the format IP1, IP2, up to IPAll. In the IPAll section - if the TCP Dynamic Ports dialog box contains 0, indicating the Database Engine is listening on dynamic ports, delete the 0.

3)In the IPAll section in the TCP Port box, type the port number you want this IP address to listen on (for example 5232 or any other number), and then click OK

4) Restart server by clicking on SQL Server Services, right click on SQL Sever (instance_name) and select Restart from the context menu

5)Allow access to this port via firewall using command like netsh firewall set portopening TCP 5232 “SQLServer2012PDB”
