Do you actually need to open it up that way?  I have this on my server
which seems to work:

server 0.us.pool.ntp.org
server 1.us.pool.ntp.org
server 2.us.pool.ntp.org
server 3.us.pool.ntp.org

restrict default ignore
restrict 0.us.pool.ntp.org nomodify nopeer noquery notrap
restrict 1.us.pool.ntp.org nomodify nopeer noquery notrap
restrict 2.us.pool.ntp.org nomodify nopeer noquery notrap
restrict 3.us.pool.ntp.org nomodify nopeer noquery notrap
restrict AAA.BBB.CCC.0 mask 255.255.255.0 nomodify nopeer notrap
restrict -6 aaaa:bbbb:cccc:dddd:eeee:: mask ffff:ffff:ffff:ffff:ffff: nomodify nopeer notrap
restrict 127.0.0.1
restrict -6 ::1


# ntpdc -c peers
      remote           local      st poll reach  delay   offset    disp
