I am looking in SQL Server Configuration Manager, 'Protocols for SQLEXPRESS'
And IP1, IP2, IP3, IP4, and IPALL have the TCP Port blank.
Should that be 1433 or it will default to that?

If you want to use a specific port like 1443 and the settings are....
The default instance will use port 1433 by default, if TCP is enabled a static port if you wish in SQL Configuration Manager.
You have to set it manually.

If so, you can use....

Otherwise it is still possible that some other process opens the port....
First open the port, then give the correct port number to the other process.
The TCP stack will allocate the next free one.
Use a port number of 0.
