To accomplish this, add the following line to NTP configuration file, where restrict statement controls, what network is allowed to query and sync time replace network IPs accordingly. The nomodify notrap statements suggest that your clients are not allowed to configure the server or be used as peers for time sync. If you need additional information for troubleshooting in case there are problems with your NTP daemon add a log file statement which will record all NTP server issues into one dedicated log file.
