Help, please! Login problem

as a first step, see if it works if you disable zonealarm completely (smartftp in general works with zonealarm as stated here: https://www.smartftp.com/forums/viewtopic.php?t=6897) to ensure the firewall is the cause. if it works without the firewall, the next step is to properly configure the firewall (just allowing outgoing connections on port 21 is not enough). see http://www.ncftpd.com/ncftpd/doc/misc/f ... walls.html for details. it's basically like this: if the server only allows you to connect via passive mode, you'll have to allow all incoming port for smartftp. if the server allows you to connect via active mode, you can limit the local port range within smartftp (tools -> settings -> connection) and allow only that range for incoming connections.

OK, thanks!

I've now got it working.

However, the most important problem I discovered was not directly due to ZAP but to an XP feature (blast William!!! ). It is necessary to stop Application Layer Gateway Service (Control Panel|Administrative Tools|Services) before anything can happen. After that, in ZAP Internet Security, allow UDP and TCP on incoming ports 20 and 21.

That is all.
