Thanks a lot @PeterUK , that works perfect. I also added the Key groups DH14 and DH19 groups in Phase 1 to enable VPN from iOS. With DH2 it did not work for me.
As I now have a more secure feeling I would like to ask if anybody of you worries about the connections attempts in the monitor logs from other countries? Since the VPN gateway is enabled I see connection attempts in the logs like this which is definetly not mine. Is that anything I have to worry about?

Exposing any port is a risk but if your patched it fine.
If you want to up the security you can have your clients run DDNS and on your side allow from source them FQDN to Zywall works really well.

Hi @Zyxel_James ,
thanks for your answer and the instruction link. I checked it and it works to get the configuration from the server, but no connection can be established. Here is what the IKE logs says:
