SSL/TLS FTP problem
« on: February 22, 2012, 05:53:37 AM »

I have try to active this SSL/TLS feature. But everytime when i use Allow SSL/TLS connection only, i lost ftp connection. Whit out this SSL/TLS feature i will get connection. So FTP is working fine over internet. But i want to use secure connection and that won't work.

I'm using Filezilla. When i use SFTP it don't get connection. Protocol: FTP -> If i use encryption: Require explicit ftp over tls, i get connection, but folder list fails. If i use require implicit ftp over tls i don't get connection.

Is there some kind secret port that i should open or something?

Firmware is 1.08.

Here is Filezilla log when i'm jusing Require explicit ftp over tls:

According to footnote #3 on page 5 of the DNS-323 User Manual:

3 Note that use of an FTP server to access files over the internet does not provide for secure or encrypted transmissions.

The Fun_plug software may provide the capability, but the software is not supported by D-Link and support would need to come from a different list.
