In Harold's defense, Feature Navigator specifically lists only the 805 and
806 with NTP support.  You mentioned you had an 805, but the command output
you showed us was from an 828.  Have you tested it on an 805?

I suppose that would work.  Just be sure to prevent unauthorized hosts
from also sending directed broadcasts, otherwise you could end us being
used as a smurf amplifier.
