Sorry, I did not explain properly. They both achieve a login but you get
the following message immediately after login
230- Guest login ok, your E-mail address is <damianm@esi..au>
230 Now you can select a FTP SERVER by cd //SERVER
200 PORT command successful [delaying].
550 cannot connect with you.
This is from a SUN Solaris 7 system. From a Linux system it works.

I am using NcFTP which does this automatically if it detects some strange
behaviour in the site or gets confused. There are many browsers and ftp
clients which do this including Mozilla. I don't know why but it has
something to do with the handshake. It might even have to do with the
proxy nature. It probably means that DeleGate is far too strict in it's
interpretation of the RFC. I am sure you understand it because you have
a whole part of your web page that obviously tries to get around this
problem where you talk about
You must show a valid E-mail address to access this server. If
you have any difficulty to do so with your WWW browser, enter
your E-mail address here ...
Anyway, even when I change the password to 'damianm@esi..au', NcFTP
just sits there and looks at me obviously waiting for some other
handshake. There is obviously still a problem.
If you want to diagnose the problem, I can send you the source of NcFTP
to go looking. I have not had a problem such as this ever before.

I assume this limitation is not from DeleGate.
There are many people who connect from sites that only allow the PASV
command and REJECT the use of the PORT command. Passive is far more
secure than PORT. We use PASSIVE as the default here for everything.
Many thanks for your king explanations.
