FortiClient IPSec Connection failure

Hallo Komune,
ich habe mal wieder ne Frage, diesmal bzgl. FortiClient.

Folgendes Setup besteht:

Server2008R2 x64, normale KMU Domain (192.168.50.10/.x/24)
Fortinet 60C
Forticlient (aktualisiert)

Connection IKE: Main mode: DH Group 5 / AES128-SHA1 / Keylife: 28800s , Nat-T: On , Freq 5s , DPD: On

Connection IPSec: DH Group 5 / AES128-SHA1 / Keylife Seconds: 28800s , Replay Detection On , PFS: On

Passphrases stimmen überein

Folgendes Log:

sys_get_local_gwy() called: [in] remote gw: 62.202.91.125. [in] Next hop: 0.0.0.0

IKE daemon stopped

Es scheint mir als das das aushandeln der 2. Passphrase nicht funktioniert.
