I am using our datacenter Fortigate as NTP server. From all the branches, could see NTP sync towards Datacenter. From DC, I am using Fortiguard as the NTP servers. My DNS reachability is fine. But still my NTP server is in unreachable state. I have created a firewall policy for this traffic, since my source interface of NTP is a different interface which will be forward the traffic to the internet interface. (But not seeing hit in that policy) I understand NTP is a self-originating traffic. Initially for few seconds, could see NTP server as reachable but later went into unreachable status. It hasnt synched post that..
Not sure, what config I am missing.
