FTP via PROXY with ICS

[NuWood]

Hi

I have used the ICS FTP Client in DELPHI 6 with great success. I have one problem though I cannot seem to PUT anything through a proxy server.

If I set the application to communicate directly with the server all is well. When I setup for proxy usage all works well except for the PUT which fails with

550 (Unable to establish data connection, error #10061)

I have tried Mailgate and Sambar FTP proxies and neither works (SAMBAR just times out on the STOR command)

Here is a log of the session for Mailgate (I have changed the site details for security) I am logging everything so there may be some duplication
