Verbindung mit proftpd klappt nicht

[Stefan27185]

{7Erstmal ein "HALLO" an alle Forum-Mitglieder!

 

Ich habe seit einiger Zeit einen FTP Server mit proftpd unter Ubuntu laufen, bis hatte ich auch keine Probleme.

Er ist so konfiguriert das ich Ihn von au?en ansprechen kann ?ber eine Implizite Verbindung (was auch ohne Probleme funktioniert.

 

Bis jetzt konnte ich aber auch immer hinter dem NAT auch darauf zugreifen was jetzt nicht mehr funktioniert.

Es kommt zwar die Zertifikatsanzeige, danach jedoch geht er ins Timeout.

Die Fehlermeldung aus der LOG datei ->

2015-06-06 11:52:41,266 FileServer proftpd[2874] 127.0.1.1 (192.168.1.60[192.168.1.60]): SECURITY VIOLATION: Passive connection from {externe IP} rejected.

 

Ich habe an der Konfig Datei nichts ver?ndert!

 

K?nnt ihr mir einen Tipp geben was ich falsch eingestellt habe.

(Ich habs schon gegoogelt, bin aber nicht weitergekommen)

Fehlermeldung gegooglet, erster Treffer:
 

You'll also need to use the AllowForeignAddress configuration directive in your configuration file:

AllowForeignAddress on

or proftpd will reject the passive transfer connections and log:

SECURITY VIOLATION: Passive connection from {host} rejected
