IPSec VPN with Fortigate

I’m working to establish an IPSec VPN between various Mikrotik as clients of one Fortigate.

The Fortigate have many FortiClient Microsoft Windows peers directly connected and also have a Linksys router conected with an gateway to gateway IPSec VPN.

Have any one some information about if it’s posible to establish a gateway to gateway VPN trough Mikrotik and Fortigate? if you know how, please tell me, I found nothing in google or in the forum.

Thanks.
