This is not our FTP server?
it's one of the clients(3rd party).

So you reckon it is badly configured FTP server causing it?
any other tips which I can ask the client to do make it visible(directory tree)?

thanks

Another thin which I noticed just now,I can see all the folders if I use CMD prompt for FTP.

that shows these folders are genuine and I can connect using the CMD but not by Filezilla.Hmm..
I am not getting it?

thanks again

I was reading another forum,I just found out it is something to do with the client's firewall blocking the connections coming from filezilla.exe.

this is what the forum recommending----------------
Basically the server needs to have a passive ftp port range opened in its own firewall and then FTP Server also needs to be configured to use this passive port range.

I am not quite sure how you wanted to do that on the firewall.
any helps would be appreciated.

Chances are good that you are not the first person to connect to this particular server so although it is possible that the problem is the firewall configuration on the remote side, it is more likely to be either a firewall on your side or that the remote server doesn't want to use passive mode at all.  

If active mode doesnt work for you then ask your local administrator if any firewall rules prevent you from making outgoing FTP data connections to the remote server on port 64809 because thats what your FileZilla tried to do and failed.


Changed the Transfer mode from passive(recommneded) to Active solve the issue.

Why it worked when I changed to Active mode.
I have a feeling now the client's firewall is not bothered about checking the traffic as it is controlled by the client pc/port itself for Active mode.
Am I right?

also I have selected Ask for OS for the external IP address.

Thanks
