Even if you use "restrict default nomodify nopeer notrap noquery" you must specify SERVER x.y.z.k so one IP address needs to be specified. If server has more than one IP address, according to my opinion, you should have having no "RESTRICT x.y.z.k" istruction in ntp.conf and that'ìs possible on

Richard, but "restrict default ignore" is more resctricted that "restrict default nomodify nopeer notrap noquery". Why should you suggest me second option ? I'should always be more comfortable with ignore for all hosts except for servers A/B even if I have no nat or Stateful inspection firewall.
