SSL VPN mit Android funktioniert nicht richtig

GL@MO

Hallo zusammen,

ich habe bei meinen Mobilgeräten das Problem, dass ich nicht auf das interne Netzwerk zugreifen kann. Geräte sind ein Z5 und ein Z4 Tablet mit der OpenVPN App.

Die VPN Verbindung wird aufgebaut und sobald ich versuche auf z.b. eine interne Webseite zuzugreifen, kommt im Log eine lange Kette von:

"read TCP_Client[]: Connection refused (code=111)"

Aus dieser Meldung und ein wenig googeln werde ich aber nicht wirklich schlau.

Jetzt mag man denken ich habe mein VPN nicht richtig konfiguriert, aber mit meinem Windows Laptop und dem SSL VPN Client funktioniert alles wunderprächtig.

Das ganze Problem existiert seit dem Update auf 9.404-5 und wurde mit 9.405 leider nicht behoben.

Hat jemand eine Idee was das sein könnte?

    (Sorry, my German-speaking brain isn't creating thoughts at the moment. [:(])

    GL@MO found the problem and posted the solution on his similar thread in the VPN forum.
