Bintec VPN 25 - Zyxel VPN IPSec

I try to configure a VPN between Germany and Switzerland. In Germany i have a Bintec VPN25 and in Switzerland a Zyxel VPN Router. I have configured AES/ Rijndael - MD5 Group 2. The Bintec found the Zyxel and accept AES MD5 and say :" Go_Up negotiating" After a minute I get during "debug all&" on Bitec : "ike_retry_limit_reached"

VPN between VPN25 and Bintec IPSec-Client works fine !

Any idear ? I need help! Thanks Carsten
