Zeitüberschreitung während der IKE- oder IPSec-Verhandlung

[majorshark]

Hallo Forum
Wir versuchen jetzt schon mehreren stunden mit einem 1721+ und 1811n via assistenten eine LAN-LAN verbindung aufzubauen. Leider scheitert die Verbindung immer an folgender Fehlermeldung:

Zeitüberschreitung während der IKE- oder IPSec-Verhandlung (Initiator) [0x1106]

1-Klick VPN Verbindungen funktionieren auf anhieb.

Aber wo liegt denn jetzt das Problem mit der LAN-LAN Verbindung?

Anbei noch show vpn und trace vpn
