Meraki MX84 IPSec tunnel Fortigate 70D

[Ferdy]

Hi,

We would like to setup an IPSec tunnel between an MX84 pair and a fortigate 70D. The Fortigate is behind a NAT device which allows IPSec. Error message at the Fortigate is: Negotiation failure. At the Meraki side:  phase1 negotiation failed due to send error. 8fc23f30749477ae:0000000000000000

Config on the Meraki side is default with very simple PSK.

Anybody got any tips on IPSec settings between Meraki and Fortigate?

We've tried several different combinations of sets.

Thanks in advance.

It Works! It was in the config of the Fortigate. Needed to build an extra phase 2 tunnel instead of putting 2 subnets in one phase 2 configuration.
