  It's not clear from your messages if you're running the server in
debugging mode for these tests.  If you are, the possible outcomes are:

  1) it doesn't receive the packet.  This usually means firewall issues.

  2) it receives the packet, and doesn't respond.  Debug output explains

  3) it receives the packet and responds, but the client doesn't see the
response.  This usually means firewall issues.

  As always, READ the debug output.  From your messages it looks like
you are NOT looking at the debug output when you send requests from
outside of localhost.
