Hi,
I have a setup with a ipsec tunnel to a Fortigate firewall.
The setup is for the most times working as expected.
But from time to time, sometime hours sometime days the a new tunnel is created to the same peer and it stops forward traffic
I have verified that I have the same lifetime on both proposal and peer, I have tried to disable dpd in both end, in one end only etc.
The only way to get it work again is to flush installed SA while there is no traffic, if I start a ping and try to flus SA it will not happen
Any suggestion regarding this issue
