Wir haben hier einen Lancom 1711 und müssen uns projektmäßig bei einem Kunden mittels PPTP einwählen. Das funktioniert von einem Rechner via "VPN Verbindung" in den Netzwerkverbindungen ganz gut. Leider arbeiten mehrere Personen gleichzeitig an dem Projekt und so kam ich inspiriert durch den Fred http://www.lancom-forum.de/ptopic,41883,pptp.html auf die Idee, die Verbindung auf dem Lancom zu hinterlegen.
Leider will das nicht klappen. Jetzt hab ich mich gefragt, ob ich hier vielleicht eine spezielle PPTP Variante habe, weil ich nicht nur Username und Passwort, sondern auch die Domaine mitangeben muss. Da ich aber gelesen habe, dass man das auch (zb. wenn man sich von einem Linux System aus einwählen möchte) mittels DOMAIN\\USERNAME erfassen kann, hab ich das so im Lancom hinterlegt.
In der Statusanzeige des Webconfig (Experten-Konfiguration -> PPTP -> Verbindunge) lese ich aber immer nur "PPTP-keine-Antw.".
Ein "trace ppp" während des Verbindungsvorganges zeigt folgendes an:
