Could you post the actual tcpdump(1) output,

  # tcpdump -vvvn 'udp && port 53'

Just in case you are missing something.

This is what I would expect for what you describe...

Hmmmm...

Could we double-check the firewall issue,

  $ sysctl net.inet.ip.fw.enable net.inet.ipf.fr_running

And see the full output of,

  $ netstat -s -p udp
  $ netstat -an -p udp
  $ host testhost            # your DNS test here
  $ netstat -s -p udp
  $ netstat -an -p udp
