I want to configure NTP Server on a router and it would be the only source for all other devices on the network ( server /routers / linux_boxes ).
The Router would be directly connected to internet via public IP on one interface.
How do I secure the router for NTP Server role only.
Router# conf t<br/> Router# ntp server 192.168.1.15 #(Public IP<br/> Router# ntp server 18.104.22.168 # Public IP<br/> Router# clock timezone PST -8
any other NTP Public Server recommended?
