Hi Alex, I totally understand it, and I know that active ftp is being deprecated, so It's logic that no further development It's gonna take place. I'm happy with Squid, and it works perfectly on 99% of my clients but two. Thank you for your time. Regards.

IIRC, the above interpretation is the right one: * We support both active and passive FTP between an FTP client (a.k.a. user) and Squid. * When an FTP client is using passive mode, the data connection must come from the same IP as the control connection. This restriction blocks attacks that steal data connection of legitimate FTP users. AFAIK, there are currently no plans (or even strong demand) to support active FTP mode between Squid and FTP origin servers.
