Description

This articles describes how FortiGate with manual time setting is not responding to NTP queries even though server-mode is enabled.

 

FortiGate with below setting not responding to inbound NTP queries on interface 'internal' -

 

# config system ntp

    set ntp-sync disable

    set server-mode enable <-----

    set interface "internal"

end

Scope  
Solution

- This is an expected behavior.

By default on FortiGate, the NTP daemon would start only if 'ntp-sync' is enabled.

Otherwise, it would not respond to the NTP client since it does not have a valid reference (manual settings are not considered).

To use FortiGate as NTP server, it is necessary to have NTP sync enabled either with FortiGuard or with custom servers as below :

 

# config system ntp

    set ntp-sync enable

    set type custom/fortiguard

    set server-mode enable

    set interface "internal"

end
