Internet über pptp Verbindung....

[Ben1000]

Hallo,

Ich bräuchte mal wieder eure hilfe. Diesmal habe ich ein Problem mit meinem Laptop, auf dem läuft Vectorlinux 5.8.

Um in der UniBib ins Internet zu kommen muss ich eine Verbindung über pptp herstellen. Das habe ich auch schon geschafft:

root:# pptp vpnintern.uni-bamberg.de defaultroute name ********
vector://home/benjamin
root:#

ifconfig und message sagen das eine Verbindung besteht:

Ein Ping auf das Gateway klappt auch:

Also klappt auch die Namensauflösung. Aber ins Internet komme ich noch nicht:

root:# ping www.google.de

Da stimmt irgendwas mit dem Routing nicht, oder?
