FTP problem with SSL/TLS connection only

Hi,

I'm having hard time connecting to my DNS-320 FTP server with SSL/TLS connection. I set up FTP server and made port:21 forwarded on router (Asus am200g).
All working O.K. I can connect and see my folders on NAS.

However when I switch to use "SSL/TLS connection only" I can't connect to server.

Using FileZilla FTP client to connect I just switched to "Require explicit FTP over TLS" and tried to connect. Here's what I get:

Response:    220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
Response:    220-You are user number 1 of 10 allowed.
Response:    220-Local time is now 12:55. Server port: 21.
Response:    220-This server supports FXP transfers
Response:    220 You will be disconnected after 10 minutes of inactivity.
Command:    AUTH TLS
Response:    234 AUTH TLS OK.
Status:    Initializing TLS...
Error:    Could not connect to server


Tried another FTP client with SSL/TLS and got this message:

AUTH TLS 
234 AUTH TLS OK. 
SSL/TLS error - 0, SSL error - 5, error:00000005:lib(0):func(0)big_smileH lib   
Winsock error 10054 (An existing connection was forcibly closed by the remote host.  ) 
SSL Connection not established


Should I forward more ports on router? Anyone experienced similar problem? If you have any ideas please let me know. Thanks for any help.

Re: FTP problem with SSL/TLS connection only

Are you using the "explicit FTP over TLS" encryption and it gives you that?
And about changing to Active Transfer Mode ?
Did it prompt any certificate warning ?

Try using the "Report external IP in PASV mode"

Re: FTP problem with SSL/TLS connection only

Hi,

thanks for help. I decided to leave this problem and try to setup SFTP server instead (should be more secure and less affect configuration of my obsolete router). Just finished installing fun_plug. Never played with Linux though so I'll need to read a lot....

Noticed that lftp application is there - I guess it can be used to start sftp server. Hopefully mr. Google will provide some nice tutorial.

Hope my steps are heading in good direction.
