Se você pode fazer com SFTP, então o livre (para uso pessoal) Tunnelier tem um FTP-to-SFTP ponte que pode ser útil. Com a ponte ativa, você pode, por exemplo, criar uma unidade de rede mapeada regularmente no Windows.
Tunnelier incorporates an FTP-to-SFTP bridge which performs translation between the FTP and SFTP protocols, allowing any FTP client application to connect securely to an SFTP server through Tunnelier. Both active mode and passive mode FTP data connections are supported, as well as restarted transfers, directory listings and other features. All FTP clients should be able to list directories and transfer files across Tunnelier's FTP-to-SFTP bridge, including integrated clients in applications such as DreamWeaver, GUI clients such as BulletProof FTP, and command line clients such as the default ftp.exe client accompanying Windows. If an FTP client you use fails to work with Tunnelier's FTP-to-SFTP bridge, let us know.
See Accessing an SFTP Server with an FTP Client for more information about the FTP bridge.
