Client to Site IPSec VPN Using Fortigate 80E behind NAT

Hi, I have Fortigate 80E in my organization, and we wanted to start using IPSec VPN Feature of it. We have NAT Firewall in "Front" of our network which we can't remove.
How Can we set up IPSec? Which ports should we forward/open, and what configuration do we need in the FortiGate except normal IPSec configuration?
Image of requested configuration in image attached.

You have to forward udp/500 and udp/4500 from your juniper firewall to fortigate. Plus any fortigate normal configuration.

Thanks! One more question. In my web interface I can't find vpn section, although it's enabled in feature visibility. Do you know what might cause the problem?
