The NTP server for ipv6 v5.2.3 FortiOS

In a pinch you can use a  fortigate as a local LAN ntp-server for ipv4 or ipv6 clients. It's not ideal imho due  that excess clients can create various issues. Also you have no  reliable means for filtering who can query your fortigate firewall as a ntp_client without deploying a local-in firewall policy.

Here in this blog, we've have a basic ntp-configuration  with the interface wifi set for answering ntp queries.

To debug ntp,  you can use fortinet wonderful diagnostic application function;

On my mac,  I'm  used the ntpq  or ntpdc query application for validate of sync.

ntptrace did not work btw
