/etc/ppp/peers/tunel. Naja hab so einiges ausgestetet aber es will nicht.
Hänge mit dem client pc hinter einer firewall (auf iptables basis,
debian woody, 2.4.18er kernel, ppp verbindung zum internet).
Wird GRE von dieser Firewall geroutet? pptp ist da leider sehr eigen!
Kann ich nicht genau sagen. Auf was müsste ich achten? Geroutet wir bei
mir eigentlich alles. Ich meine also ich habe bis jetzt nicht explizit
(bewusst) bei den iptables auf GRE geachtet. Wenn ich mich von einem
Windowsclient durch die Firewall hindurch mit dem VPN-server verbinde
funktioniert es. Darum bin ich auch davon ausgegangen, dass es auch mit
nem Linux-Client funkst.
Habe auch Versucht mich direkt mit dem Rechner (mit VPN-Client) an das
DSL Modem anzuschließen und so den Tunnel aufzubauen. Einwahl zum
Provider ging 1a. VPN Verbindung gleicher Fehler.
Bei meinen Verschuchen habe ich die Konfiguration vom howto
(http://pptpclient.sourceforge.net/howto-debian.phtml) verwendet.
Die Verbindung wird auch aufgebaut (iptraf zeigt es jedenfalls) jedoch
wird die verbindung dann unterbrochen.
Was sagen die Logfiles?
aus der Syslog.
