No SFTP in ReadyNAS 2312; best public server alternative?
I've set up a new ReadyNAS 2312 primarily as a local backup destination but now that it's in place I'm thinking of other uses for it. I regularly transfer multi-GB files to individuals, and have...
The NAS is not set up for individual file or folder permissions, you'll need one or more shares for sharing. And you'll also have to poke a hole in your router firewall.
ReadyCLOUD may be an answer, but I recommend you also look at OwnCloud or NextCloud rather than use the NAS authentication system for occasional guest users. That's what they were built for (though they've been expanded to do much more over time) You can get a ReadyNAS ready version of either at https://rnxtras.com/ for a very reasonable fee.
I use OwnCloud myself. NextCloud was in the very early stages when I implemented it, and I just stuck with what I know. I'd probably choose NextCloud today if starting fresh.
Do you have a static public IP address and/or domain name? One of the issues you may have is installing an SSL certificate so that the user doesn't get that same warning about the site being unsafe that you do. That might turn customers away. And a domain name (which can be via dynamic IP, but is easier with static) is required for installing the certificate. ReadyCloud does avoid that part of the process as well as the poking a hole in the firewall.

FWIW: ReadyNAS has FTPES implemented, not FTPS.
Correct. But not much difference in practice.
- FTPS is implicit FTP over SSL/TLS
- FTPES is explicit FTP over SSL/TLS
FileZilla and (I think) WinSCP treat them as one protocol with an option for explicit/implicit. And the NAS (like WikiPedia) just calls both FTPS. So I generally do also.

The FTP server can be configured so only the encrypted FTPES can be used for both the control and data channel. So what was the security concern again?
If I recall correctly, it was more a fear that FTPS was "old and hackable".
Both FTPES and SFTP are considered secure. The differences are that
- SFTP has option support for SSH keys, while FTPS/FTPES does not
- FTPS/FTPES requires more ports to be forwarded in the firewall.
Big difference StephenB ... look here: FTPS does imply using a dedicated port for an FTP TLS session, the default is 990/TCP. This is nowhere implemened by ReadyNAS, and can't be configured. Thus, the designation FTPS is more than just misleading. FileZilla as a popular FTP client does (correctly) talk of FTP, and allows using "Use explicit FTP over TLS if available" (the default, if available it's FTPES), "Require explicit FTP over TLS" (so it does not connect over plain text FTP, FTPES again), or "Require implicit FTP over TLS" (that's FTPS - not available on the ReadyNAS).
