I was talking about masqueraded connections (or statefull packet filters). Both tend to clear connections from the memory table after some amount of inactivity. If you transfer large files, then during the transfer over the data connection there is usually no data running accross the control connection. Generally this means the Firewall will timeout the control connection during the transfer. The FTP programm will barf at the end of the data transfer if it tries to go back to the control stream. This is not a problem for simple packet filters, but I'm not surer if a simple packet filter is state of the art for a good firewall.
