NTP server issue

Hi,

I use a box to provide NTP services to my routers. Using the following command

router(config)#ntp server 1.1.1.1 prefer

I configured my routers to sync with that Box. I just found out that my routers are now accepting NTP sync requests!! Is this a normal behavior? Is there a way to block NTP sync requests other then ntp disable on each interface or an access-list on every interface ?

Thanks
