also ich hab auf meinem Raspberry Pi Proftpd und einen Siemens SE551 Router. Port 20 und 21 sind als TCP freigegeben.
Ich hab folgendes Unternommen
etc/proftpd/proftpd.conf mit nano als root geöffnet
Default Required Shell auf off gestellt und die Raute davor entfernt
Group hab ich glaub ich auch geändert, bin mir aber nicht sicher. in der config kannst du ja umstellen in welcher Gruppe die User sein müssen damit sie sich einloggen können
bei Default Root Raute davor entfernt
die /etc/shells mit nano editiert bzw. folgenden Eintrag geaddet
/bin/false
Danach musst du im ftp Verzeichnis einen ordner anlegen und einen user mit der /bin/false shell und dem Home Verzeichnis adden das du erstellt hast.

Code:
#
# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes, reload proftpd after modifications, if
# it runs in daemon mode. It is not required in inetd/xinetd mode.

# Includes DSO modules
Include /etc/proftpd/modules.conf

# In some cases you have to specify passive ports range to by-pass
# firewall limitations. Ephemeral ports can be used for that, but
# feel free to use a more narrow range.
# PassivePorts 49152 65534
# If your host was NATted, this option is useful in order to

# To prevent DoS attacks, set the maximum number of child processes
# to 30. If you need to allow more than 30 concurrent connections
# at once, simply increase this value. Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service

dann noch mit
das ganze neu starten
Die Routine wenn du einen neuen Benutzer anlegst.
adduser neueruser -shell /bin/false -home /dein/verzeichnis
adduser neueruser ftpgruppe
chown -R neueruser:neueruser /dein/verzeichnis
chmod -R 770 /dein/verzeichnis
Beispiel bei meinem Raspberry Pi mit deinem Forumnamen
mkdir /media/ext/ftp/shilzarion
adduser shilzarion -shell /bin/false -home /media/ext/ftp/shilzarion
Passwortabfrage 2x mit dem Passwort deiner Wahl (Eingabe+Bestätigung wegen Tippfehler)
Die anderen Abfragen wie Zimmernummer, Telefonnummer usw überspringst du mit paar mal Enter dann J bei der Frage ob die Informationen korrekt sind
adduser shilzarion ftp
chown -R shilzarion:shilzarion /media/ext/ftp/shilzarion
chmod -R 770 /media/ext/ftp/shilzarion
Voila erledigt, du kannst dich mit jedem x beliebigen Clienten (Filezilla, Windows GUI, cmd, AndFTP für Android usw.)
Edit: User löschen geht mit userdel shilzarion
User sperren mit usermod -L shilzarion
User entsperren mit usermod -U shilzarion
