We have 2 standalone Azure Fortigates (7.0) in a load balancer sandwich, managed by FMG. We're looking to replace the Azure VPN gateway with IPSec on the Fortigates to our onprem Fortigate cluster.
I'm looking for a reference design for the IPSec tunnels and associated routing or if anyone has done it this way?
Currently i have dialup tunnels from Azure fortigates to onprem but failover and loadbalancing doesn't work so well. I'm thinking perhaps i need OSPF or BGP but am unsure.
Any tips?

Hi there,
Looking at your issue, this is more to designing the solution.
Do you mind to share your network diagram so i can get some idea?
Hi
We have a basic 'active-active' set up with loadbalancers as per the admin guide. Azure has one public IP. The onprem FG is a standard A-P ha cluster.
There will in the future be a requirement for further IPSec tunnels to the azure side from other third party sources.
The idea was to get full use of both azure fortigates rather than a standard A-P set up. From what i have heard so far this may be possible but not perhaps advisable or best practice.
I have also spoken to our local SEs and they are investigating as well
