No, it not as simple as that. Because NTP uses UDP there is no previously established connection to respond on. There are a number of other reasons to avoid using wildcards, including autokey and firewalls which expect responses to packets from the same address to which the outgoing packet was sent. There is code that will allow you to specify which IP addresses to open and which to send queries out on but it's not yet available while we resolve some configuration questions. See http://support.ntp.org/bin/view/Dev/NtpdAndNetworkSockets for what we are looking at doing. Note that this issue has been extensively discussed and you should find them in the archives.
