[Eisfair] VPN-Tunnel E1

[Jürgen Witt]

Hallo NG,

ich setze einen Eisfair-1 (base 2.2.4, kernel 2.4.1 
(2.6.32-eisfair-1-SMP)) nur für den Aufbau eines VPN-Tunnels (Paket vpnd 
0.4.5) ein. Das funktioniert auch seit Jahren problemlos. Jetzt hat 
jemand versucht mit einem aktuellen Android-Handy eine VPN-Verbindung 
aufzubauen, aber keine Erfolg gehabt. Die Daten (Servername, User und 
PW) sind korrekt. Mit den gleichen Zugangsdaten von einem iPhone 
funktioniert es problemlos. Hier der Mitschnitt (erst der Androide, dann 
das iPhone):

Habe ich eine Chance, es auch auf dem Android-Handy zum Laufen zu 
bekommen? Beim vpnd-Paket selbst gibt es ja fast nichts einzustellen.
