Actually, I see in your original post that your port is 1433. That looks to be the default port for SQL Server.
If that is the database you are using, I wonder whether using SQLServer as your driver is a better bet than FreeTDS. If so, you will probably need to change your connection parameters to match the driver documentation:
You will probably want to use a "DSN-less" connection string, which is described on page 37.
The other questions I asked should still be addressed, please, as they would potentially prohibit any of this from working.
