Hi, do you know if ther is a fortigate config that allows creating two VPN tunnels to the same peer id but one being IKEv1 and the other tunnel IKEv2 with differents hosts in phase 2? Without showing you the error on the remote gateway "Duplicate entry found"

The subject and description are confusing at least to me. Are you trying to configure two IPsec phase1-interfaces to two physically different hosts but "Peer ID" (local ID on the peer sides) for those are the same?
Then why can't you just set different peer IDs (local IDs on the other ends)? If local IDs are the same, that's not a valid ID (identification).
