How to set up ntp on freebsd for dlink switches?

Question

FreeBSD

Set up a FreeBSD server to synchronize time for dlink equipment.
You can see from the traffic that there are requests from dlink. There are no answers from FreeBSD itself.

restrict localhost

restrict ru.pool.ntp.org
restrict 1.ru.pool.ntp.org
restrict 2.ru.pool.ntp.org
restrict 0.ru.pool.ntp.org
