SQL Server is a Winsock application that communicates over TCP/IP by using the sockets network library. SQL Server listens for incoming connections on a particular port. The default port for SQL Server is 1433. The port doesn't need to be 1433, but 1433 is the official Internet Assigned Number Authority (IANA) socket number for SQL Server.<br />

Hi<br />
<br />
I know what the port is, but what I'm looking for is from Visual basic .net, how do I add this port to the firewall's exception list.<br />
In other word, I want to write a piece of code that adds port 1433 to the exception list.

I'm looking for a way to get the Port number SQL server is running on (if possible)<br />
and then add that port as an exception to the windows firewall for a VB.net application.
