We are attempting to change our communication port used by SharePoint from 1433 (default SQL port) to something else.
- On our SQL server, we have changed the ports within SQL Server and cliconfg.exe (by way of creating an alias).
- On the WFE server, we've created an alias pointing to the new port with cliconfig.exe.
Speaking with our networking team, we ensured that the new port was opened, and we attempted to run through the configuration wizard. It fails on step 3 (connecting to the configuration database). This is strange, because in the SQL Server Log Viewer, it shows that our SP account logged in to the SQL server correctly (this would be from the Configuration Wizard, when we enter the Passphrase). So we enabled both the new port AND port 1433. SharePoint's Configuration Wizard succeeded.
Apparently traffic coming from the WFE is popping back and forth between port 1433 and the new port, from what the networking team said. Yet, other than in cliconfig.exe (on the WFE), I'm not certain where to change the port for SharePoint to use.
I tried putting in the new port in the textbox in the Configuration wizard where it asks for the Database Server name (to click "Retrieve databases" so that it grabs the configuration database name) - and this works, it DOES grab the configuration database name, even when port 1433 is blocked..
Any thoughts/information would be appreciated.
