local ntp server does not work

Hi, Guys,

 

I am using Fortigate 400E HA with FortiOS V7.0.3 and some SDWAN configurations; but found the local NTP servers do not work for LANs, as the following:

 

Forti400e_01 # config system dns
Forti400e_01 (dns) # show
config system dns
set primary 208.91.112.53
set secondary 208.91.112.52
end
Forti400e_01 (dns) # end

 

Forti400e_01 # diag sys ntp status

Problem:

DNS works, External NTP works; But local NTP server for LAN does not work; for example:

LAN client 10.32.9.253 can not sync with the Local Fortigate Server/10.32.9.254. 

 

Any recommendation/advice ?

 

Many thanks

Hi, guys,

 

further checking of the Fortigate 400E HA status, something found as below:

 

Forti400e_01 # diag sys smc-ntp
status List SMC NTP setting.

Forti400e_01 # diag sys smc-ntp status
SMC NTP status: 0
Channel: 0
Link status: 0
Current NTP server IP address: 0.0.0.0
Timezone: 0
NTP poll interval: 0
NTP server 1 IP address: 0.0.0.0
NTP server 2 IP address: 0.0.0.0

 

 

After adding the default NTP servers, the "show" is same result:

Forti400e_01 (smc-ntp) # show
config system smc-ntp
set ntpsync enable
config ntpserver
edit 1
set server 208.91.112.51
next
edit 2
set server 208.91.113.70
next
end
end

Forti400e_01 (smc-ntp) # get

Any suggestion or recommendation, thx ?

It is wired, when the local NTP server for only one interface, the local NTP server works;

After that, the local NTP server for many interfaces also work.

I am still finding out the issue.............

 

Anyway, the Fortigate local NTP server works, as the following test:
