ws-ftp client error


I have a ftp server behind a load balancing firewall. When I have the ftp server infront of the firewall then I don't have any problems connecting to it from a work station. When I have the ftp server behind the firewall I get this error:

connection refused; the server would not accept an FTP connection

I know the connection from the client is getting to the ftp server behind the firewall as I can see it when I am listening from the ftp server on port 21.
Is it possible that it is trying to connect via some other method that is not getting through the firewall that is not on port 21.

Here is the whole printout of the transaction between the client and the server.

I figured it out. It connects on port 21 and it connects on a non-private port.
