This is most surprising!
I am also using DI-804 and my checks with ShieldsUp report that
my local network is completely invisible to Internet (Stealth mode).

So I tried your sygatetech scanner which gave a report similar to
what you experienced:
all my UDP ports were accessible but closed.

There is only one unanswered question: What happened to the
scan on those UDP ports that were open on my computer?
(Yes there are a few). Obviously the sygatetech scans cannot have
reached my computer, so what was it that responded to the scan?

I do not know, and frankly I am not worried because all other
relevant tests show that with the gateway and NAT functions in my
DI-804 (and Kerio running in my computer) I can feel pretty safe.
