The resolution ended up being to comment out: restrict default ignore
from the default ntpd.conf After I commented out that line, I was able to get updates from the servers I had configured, as well as provide updates to client devices. For those coming upon this in a search engine result, please be advised that this may have security implications that I don't know about... For my application, the server is behind a hardware firewall in a fairly controlled network, so I'm not too concerned; but if you're running an internet server find out the proper command syntax for the most secure operation!
