I recently tried to connect 2 VM FortiGate together to simulate 2 locations separated with 2 point-to-points links (SD-WAN redundancy). I have an Ubuntu connected to each of this FortiGate. I think I did setup all the interfaces correctly as well as the SD-WAN / IPv4 rules / static routes but the problem I'm facing is that I can only ping from LAN2 to LAN1, not from LAN1 to LAN2. But I can still ping from LAN1 the external interface (point to point) of the FortiGate connected to LAN 2. Something might be messed up in the FortiGate of LAN2.
