425 Error: Possible bounce attack / FXP transfer

Hello
I have problem with transfering data to one FTP server. Login to this server is OK.
I am able to create my directory on this server, but when I try send there some file,
I receive this message:
150 Opening binary mode data connection for /codico 05-01tisk1.pdf.
425 Error: Possible bounce attack / FXP transfer
221 You have been kicked.
What it means? Is this error in SmartFTP settings on my comp or is problem on FTP server?
I have no problem with communication with many other FTP servers only with this one.
Thanks for any useful advice.

Hi, are you trying a server to server transfer? if yes, the answer is that the server don't allows that, if no try to change Tools->Settings->Connection->Data Connection->Mode from pasv to port.
