In some mail from Simple Nomad, sie said:

Yes but if the firewall or router is simply dropping the packets (common
with filter-based rules) then all UDP ports will show up as open, when in
fact they are not.

I think that a 'script kiddies' work arround may be:
if nmap found all UDP ports open print 'Warning, seems that all UDP ports
are open, maybe that outgoing type 3 ICMP or ingoing UDP packets are
filtered, bla bla'.
