Yes. Every FTP connection uses two ports. | The ftp client is set to passive mode. Set it to active mode (this will work because you opened your whole firewall). In passive mode the client must be able to open the second connection to the server. In active ("normal") mode the server opens the connection to the client. This is why at least one of the systems must not be behind a firewall. | Running Zope 2.5.1 on RedHat 7.0 with Apache 1.312 | | Every tip would be very much appreciated Can you use HTTP or WebDAV? They don't require that nasty second port. -D -- How great is the love the Father has lavished on us, that we should be called children of God! 1 John 3:1 GnuPG key : http://dman.ddts.net/~dman/public_key.gpg
