Hi ShivSagar, thank you. Yeah, in the firewall policy i logging all allowed traffic. With the packet debug flow i see the packet that i send in both fortigates coming in the VPN interface. But still it doesn't ping, what I notice in both fortigates on the IPSec monitor is that there is only Outgoing Data and no Incoming Data.
I don't know what else to do, and I eliminated the VPNs and recreated them, I did a flush and reset the tunnel and it remains the same :(
