Problem with probing the pre-shared key..

Hey,

i have a big problem with the configured pre-shared key of a vpn connection:
I have two groups of vpn Users connecting IPSEC per PSK and XAUTH

Group One
Preshared Key ONE

Group Two
Preshared Key TWO

The Problem is now, that the second connection (Preshared Key Two) cannot be established wenn the first connection was established once (Preshared Key One)

Only if i set the connection from green to red and then back from red to green, everything works fine.

Strange Thing is that a user from the second connection group (Group two)is logged (IPSec-Log) with the name of the first connection (Group One)

Probing of shared keys is enabled!

Can anyone help?

Cheers
Frank
