SOLVED Why is FreeNAS making outbound UDP connections port 123? How to stop?

[sfjay]

Noticing outbound traffic attempts from newly installed FreeNAS to target IP's:

208.79.89.249 port 123 (zeit.arpnetworks.com
108.61.73.243 port 123 (hydrogen.constant.com)
108.61.73.243 port 123 (helium.constant.com)

I'm guessing these are NTP requests to the default NTP pool servers for:

0.freebsd.pool.ntp.org
1.freebsd.pool.ntp.org
2.freebsd.pool.ntp.org

SOLVED: Yes, that was it.

I removed these and changed to our internal NTP server.
