E4200v2 FTP server setup

Hi,

I am making use of the USB port on this router to connect an external hard drive. I would like to access this drive from outside my local network via FTP. What sort of settings should I use when configuring the FTP server to ensure maximum security?

Thanks

I own a E4200v2 and wanted to do this some time ago. But then I realized again how "unsafe" FTP actually is. First off the E4200v2 does not even support sFTP.
then for passive FTP one has to open a lot of ports:

FTP server's port 21 from anywhere (Client initiates connection)
FTP server's port 21 to ports > 1023 (Server responds to client's control port)
FTP server's ports > 1023 from anywhere (Client initiates data connection to random port specified by server)
FTP server's ports > 1023 to remote ports > 1023 (Server sends ACKs (and data) to client's data port)

Not my cup of tea. Not worth it IMHO.

I got myself a proper NAS server and connect with VPN when I need access to my files from outside my network.
