FileZilla Forums

I would like the majority of my users to use FTP over TLS. However, I have a couple of processes that must use unencrypted FTP over port 21. I would like to restrict the plain FTP (port 21 access) to specific IP addresses. Is this possible? How would I implement?
Thanks.

Unfortunately no. You would need to use a separate instance of FileZilla Server listening on a different port or IP address.
