Hallo

Habe pppd und pptd durch neue Versionen ersetzt und den verschiedenen 
Optionen in der options.pptpd probiert.

Jedoch mit gleichem Ergebnis mit Kernel eiskernel: 2.10.0 
(3.2.67-eisfair-1-SMP) wird bei erfolglosen Einwahl vom Windows-Client 
folgendes ausgegeben:

Kann der neue Kernel kein GRE oder ist darin etwas geändert, so das 
keine erfolgreiche Verbindung entsteht.

In der Hoffnung, das ich nicht der einzige Nutzer von VPNd auf Eisfair bin.

Gruß Frank

PS:

Nach Wechsel des Kernels auf 3.2.54-eisfair-1-SMP wird die Verbindung 
mit folgendem Protokoll erfolgreich aufgebaut:
