<br>
Similar to the Windows problem you had earlier, you don't have the correct combination of configured algorithms. look at the logs:<br>
<br>
May 10 20:26:48 vpn-server charon: 12[IKE] DH group MODP_2048 inacceptable, requesting MODP_1024<br>
<br>
The iphone expect modp2048, but your configuration says modp1024. Look back at the suggestion we made for Windows and just use the same configuration.<br>
<br>
Regards,<br>
