Secure FTP from a single domain only

L2 Linker

I have an inbound SFTP, I need to secure access to from only a single domain, say * I have tried with a URL category in the security policy. This does not seem to work. The source is in AWS, so to much of a hassle to manage a source ip list to allow. The source owner says he is AWS-US-EAST-1 zone. However the source IPs he listed are in Palo Alto EDL Hosting service, AWS US East Amazon AppFlow IPv4.

Any suggestions?

I'm guessing as no one has replied this is not possible? If that is correct, please saw so and I'll go another route.

Since it is SFTP, there is no URL involved, so you can't filter with that. You would need to have a specific resolvable FQDN for the source server(s) (you can't have wildcard FQDNs) or an IP list of the source servers.
