My issue is few days ago Forti to AWS IPSEC VPN was down. but didn't work the DPD function.
AWS sent to me this log.
2020-07-03T03:44:38.496 recieved DPD R_U_THERE_ACK seq number 324617111
2020-07-03T03:44:48.492 sending DPD R_U_THERE with sequence number 324617112
2020-07-03T03:44:58.492 sending DPD R_U_THERE with sequence number 324617113
2020-07-03T03:45:08.492 sending DPD R_U_THERE with sequence number 324617114
2020-07-03T03:45:18.492 DPD check failed, declaring peer dead.
but I can't find about DPD failure and tunnel Down in fortigate VPN log.
There is only phase 2 Down Log.
I want to know if it's a bug or a config values error.
when the VPN was down dpd config is on-demand, 20 seconds 3 times.
