This may be in relation to the latest WinXP updates, as I now have partial and complete failure with FileZilla FTP Client (latest) and connect to FTP servers. Solution found for now. Disable Eset Smart Security Firewall Error log, says something like.. No rule for this & ftp address. Have tried Learning mode, but the Learning mode does not catch what happens. Tried Auto with the exception of all ports available to the FTP server address and local. This helped a bit.. but FTP performance is poor, meaning a lot of failures during transfers, zero byte uploads, timeouts etc. Without firewall activated, the FTP performance is excellent. Believe some of those default system configuration settings for things like Generic Host Process.. etc are involved, but I really don't know. Bummer is that I've paid for 2 or 3 years for this program and I find it weird that basic things like FTP fails.. in both Active and Passive mode.
