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:
