FTP Server von außen unter nicht standardmaeßigem Port

Erster Beitrag
Hallo!

Ich betreibe einen FTP Server wiefolgt und habe das nachstehend genannte Problem, bei welchem ich um Hilfestellung bitte:

Daten wie unter diesem Link gefordert: https://www.supernature-forum.de/ne...ver-ftp-server-funktioniert-dann-starten.html

Betriebssystem: Raspbian wheezy
Internetzugang: Telekom Austria, Router: Thomson TG 585 V7
Serversoftware: vsftp 2.3.5
Konfiguration (siehe unten)
keine mir bekannte Firewall
Nutzung von DynDns Service

Ich betreibe unter dieser DynDns Adresse bereits einen http, telnet und ftp server die tadellos funktionieren!
Habe nun den Apache Server am Raspberry auch schon auf einem nciht standartmäßigen Port zum laufen gebracht und kann von außen darauf zugreifen.
Der FTP Port liegt beim Raspberry auf Port 201. Die Konfigurationsdatei vsftpd.conf ist wieter unten. Im lokalen Netzwerk funktioniert das auch.
Am Router ist eingestellt dass er den port 201 zum raspberry weiterleiten soll. Der Raspberry hat im lokalen Netzwerk die IP 10.0.0.15.

Wie kann ich einstellen, dass das mit dem port 201 auch mit Zugriff von außen funktioniert??

Vielen herzlichen Dank im Vorraus!

Mfg Max

# Example config file /etc/vsftpd.conf

# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's

# Run standalone? vsftpd can run either from an inetd or as a standalone
# daemon started from an initscript.

# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO

# Uncomment this to allow local users to log in.

#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
#local_umask=022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will

#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.

# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,

#
# By default the server will pretend to allow ASCII mode but in fact ignore

# You may specify an explicit list of local users to chroot() to their home

Hallo und herzlich willkommen bei uns :)
Das sieht nach dem klassischen PASV-Problem aus - der Server schickt im PASV-Kommando seine interne IP-Adresse, damit kann der externe Client natürlich nichts anfangen.
Es gibt für vsftpd die Variable pasv_address - da Du aber keine IP-Adresse dort eingeben kannst, weil die ständig wechselt, muss dort der DynDNS-Name rein.
Ergänze die Konfigurationsdatei mal noch um folgende Einträge:

pasv_addr=dyndns-domain
pasv_addr_resolve=yes

Möglicherweise musst Du auch noch einen Bereich für die PASV-Ports festlegen, z.B.

pasv_min_port=32000
pasv_max_port=32100

Diese Ports müssten dann noch zusätzlich im Router freigegeben werden.
