By the rerror message it looks as if the server + firewall combination of the FTP server are rejecting the connection, not that there is anything wrong with your connection specs. The PORT command and PASV commands are used to open up communication for reading and writing data.

I would try connecting with an FTP client outside of your SSIS package to see what properties you need to set (I find Flash FXP good for this but there are lots of free ones on the mkt) and check the logs on the FTP server (if there are any) to see why the connection is not getting through.

You can also check firewall settings (if there is a firewall in between) to see if any ports are blocked, and what messages are being reported there.
