Hi Derek,
This depends on what you are trying to connect to. If you are trying to do a FTP connection, then you probably will use the default FTP port, which is 21. If Telnet, then you will use the default Telnet, which I think is 23 For HTTP, default is port 80. If you are connecting to a non-default application or server, then you need to find out what port the server is listening on to determine which port to connect to. For more defaults, I would google for "default ports" to get a default port list.
