When you say "The [FreeBSD] machine goes out to the net and updates
it's time" do you mean that you are running ntpd on the machine, and
it is getting time from another server, or do you mean that you are
periodically setting its clock by fetching the time from the server?
If you don't have ntpd running, nobody is listening to UDP port 123.
