John:
It had not occurred to me to open UDP on those ports also -- but
that did the trick. You sir, are a gentleman, a scholar, and
undoubtedly a fine judge of good whiskey.
Tnx, Howard

Just one other thing. Make sure that you told the firewall to open UDP
(not TCP) port 123 for ntp. Again, I don't run DNS, but I seem to
recall that it wants both TCP and UDP opened for port 53.
