Locking down access from dynamic IP?

#1 Post by jack_l » 2019-05-14 11:02

I would like to lock a FileZilla FTP server down (basically as it is already setup) blocking all and only allow set IP. However, the connecting client doesn't have a static IP and so manually updating this allow IP is a bit of a pain.

The client has a CNAME record linked to the dynamic IP so I would like to be able to update the allow IP based on a CNAME record (that the Server checks to reduce the chance of spoofing) and it would always used in conjunction with a very strong password.

Is there any way to do this?

To my knowledge, it's not possible. Only static IPs and IP ranges can be blocked.

Sounds rather like a job for a good firewall.
