Hello Joachim,
we would install a PROFTPD Server in a DMZ behind our Firewall. We have installed a WEB-Server in the DMZ and a Mail-Server in the internal Network. Both of them works very well. If we access the FTP-Server via WEB we see the login message and the ftp-prompt. A pwd and cd runs perfect. If we do a "dir" or "ls" we see the line "220 Port Command successfull" and nothing goes on. The same comes from internal net.
Which port have to be opened, that we can access the ftp-Server? ftp uses port 21 for the commands and port 20 for the data. If you say "ls" or "dir", the output sent to your terminal is already data.
