ZD1200 not obeying NTP server configuration
ZoneDirector 1200 version 10.1.1.0 build 42
NTP is enabled, with NTP server specified, for example "ntp.example.com". The real NTP server address is our internal NTP hostname with 2x A records and 2x AAAA records in DNS.
But looking at packet capture, the ZoneDirector is going to random NTP servers to ask for time. Example list of NTP servers ZD is observed as using:
18.104.22.168 - ntp.hkg10.hk.leaseweb.net
22.214.171.124 - ns1.botsnet.bw
126.96.36.199 - ntp3.inx.net.za
188.8.131.52 - time4.aliyun.com
It looks like ZoneDirector uses some internal hard-coded list of NTP servers.
If I specify an NTP server in ZoneDirector configuration, I expect ZoneDirector to not use any other NTP server.
Confirming from CLI "show config" (real address and TZ censored):
