The issue with ftp downloads using FileZilla

Hello, VirtualBOX is an excellent product. At Home any crashes during execution of VMM. Although it is a bug in the NAT network controller when I transfer a file to an FTP server using the latest version of FileZilla, file size is croped of one bytes and this container (son contenue) is different from the local file. When I transfer files to FTP using Total Commander, this seems OK.

When I go into network bridge, and I transfer a file to FTP server by FileZilla software , it's OK.

In my opinion: The bug comes from the buffer controller of NAT, I think when FileZilla sends it the data via the NAT network of VBOX, the buffer is reseted (by host VBOX) before sending the packet to the network HOST. The data buffers are overwritten before or during the sending sends data. I'm not sure.
