I am trying to deploy ftp 7.5 with SSL.
SSL is configured with (microsoft) self-signed SSL certificate. IIS/FTP Server is in DMZ with NAT IP for internet.
From the internal network I can use WinSCP (passive mode) to connect over SSL, but from the outside I get the dreaded "Could not retrieve directory listing. Server cannot accept argument."
If I disable SSL on the FTP server I can connect and browse the FTP site from the internet.
For testing purposes my CISCO ASA is allowing all IP from my Home computer (only) so I don't think the ASA is the problem.
Per the windows firewall, I have added the "netsh" commands to allow secure FTP over SSL (FTPS) traffic.
Anyone had success getting SSL to work from external IP addresses?
