Hi Experts,


Any ideas why a random NTP server from the Internet can access to my router via NTP although there is an access-list configured?  Thanks



R1#show run | s ntp


ntp access-group query-only 1


ntp server X.X.X.X


R1#show access-lists 1


Standard IP access list 1


    10 permit X.X.X.X


Output of NTP server at <router IP>

ntpdate

server <router ip>, stratum 0, offset 0.000000, delay 0.00000
