FTP Server

After enabling the FTP server setting, you will be able to access your NAS via any FTP client program (i.e., FileZilla). FTP server access rights are the same as those for the system (ADM). Should you wish to change or configure these access rights, you may do so using the shared folders setting found in the Access Control system app.

  • General:
    • Unicode support: Please enable this option if your FTP client program supports Unicode.
    • Enable anonymous: Enabling this option will allow FTP client programs to access your NAS anonymously, without the need for a username or password. For security reasons, this is not recommended.
  • Advanced:
    • Enable SSL/TLS: Enable encryption for FTP connections.
    • Enable FXP: FXP stands for File eXchange Protocol. By enabling this option, FTP service will support server-to-server file transfer function.
    • Maximum number of all FTP connections: The maximum number of simultaneous FTP connections allowed.
    • Maximum number of connections per IP: The maximum number of connections allowed per IP or system.
    • Max upload rate: The maximum upload speed per connection. 0 represents no limitation.
    • Max download rate: The maximum download speed per connection. 0 represents no limitation.
    • Passive FTP: To minimize the security concerns of connecting from a server to a client, a type of connection mode called Passive Mode (PASV) was developed. When a client program starts to connect, it will notify the server to activate Passive Mode.
    • Respond with External IP for Passive FTP request: By enabling this option, the server will report its external IP address to FTP clients. This option only works when the ASUSTOR NAS is behind a NAT, and the FTP clients belong to a different subnet than the ASUSTOR NAS does. In most cases, this option is unnecessary, but if FTP clients fail to connect to the ASUSTOR NAS, then you can enabled this option and try again.

About Passive FTP

Passive mode FTP can be used to overcome the problem of active mode FTP being blocked by firewalls. Passive FTP makes the FTP client establish all connections to the FTP server, as opposed to the web host supplying the return port. Firewalls typically allow passive FTP connections without requiring additional configuration information.
