A new wizard can be used to create Dial-up IPsec VPNs for FortiClient and Native iOS IPsec clients. The FortiClient configuration can be used for all platforms supported by FortiClient. Find the wizard by going to VPN > IPsec > Auto Key (IKE) and selecting Create VPN Wizard.

See http://docs.fortinet.com/sysadmin.html for more information about using the VPN Creation Wizard.
