As per my understanding, ntp service will always bind with port 123.

I have tried ntpport option mentioned in https://docs.ntpsec.org/latest/ntp_conf.html. But, its not working.

Is there any option available in ntp.conf to bind another port with service Or NTPD will always listen on 123 port only?

Have you checked its listening on the new port? `netstat -a` and if it is, have you remembered to allow it through the firewall on the new port? – user3788685 Mar 31 '21 at 18:46
Note you need root/admin-level access to bind to port 123 – CodeMonkey Apr 23 '21 at 00:16
