Hallo Forumsteilnehmer,
ich hoffe, mir kann jemand bei dem Problem helfen.
Ich versuche eine VPN-Verbindung per PPTP herzustellen, doch leider kommt keine Verbindung zu stande.
Probiert habe ich es mit dem network-manager und auch über ein Windows-XP in der VirtualBox. Als WAN habe ich sowohl einen UMTS-Stick, als auch über LAN und Router zu durch Kabel-Deutschland.
Mit meinem Galaxy Nexus und dem integrierten VPN-Client konnte ich eine Verbindung sowohl per UMTS als auch über den Router herstellen.
Hier ist ein tcpdump-Mitschnitt beim Verbindungsaufbau über UMTS durch den network-manager (IP des VPN-Servers habe ich in Remote_Host umbenannt und die von meinem Rechner in Client-d1-online)
tcpdump -i ppp0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on ppp0, link-type LINUX_SLL (Linux cooked), capture size 65535 bytes
