FTP timeout using proxy

[cir_tech]

My office uses WinGate 6 to regulate internet access. I have trouble connecting to a particular FTP site using any GUI client, although there is no trouble using a command line client. There is no problem connecting from outside of the proxy or from the proxy server itself.

Any clues? Another FTP site works fine. Here is my FTP client's activity log:

Looking up 128.1.1.254
Trying gateway:21
Connected to 128.1.1.254:21
220 WinGate Engine FTP Gateway ready
USER pickels@ftp.pxxxxxxxx.com

331 Password required for pickels.
PASS xxxx
230 User pickels logged in.

200 Type set to I

257 "/" is current directory.
PASV

227 Entering passive mode (128,1,1,254,17,155)
LIST -aL

Connection to ftp.pxxxxxxxx.com timed out
Disconnecting from site ftp.pxxxxxxxx.com

Can you change your client to use "Active" mode, rather than passive mode? See if that works.

That was the problem. Thank you for your help.
