Does that mean that the SQL Server is using a different port for each instance, and that the port might not be the same every time?
I have read that the browser service is using UDP on port 1434. Is the SQL server still using port 1433.

Is it correct to specify the instance name after the IP address (123.123.123.123/MyInstance)? Could I also specify the port after this (123.123.123.123/MyInstance,1433) and not need the browser service?
