Re: UDP zero checksums and v4 to v6 translators

 In your previous mail you wrote:

   I strongly recommend that people read section 1 of RFC 2765. Here is some of
   the relevant text:
   
   Fragmented IPv4 UDP packets that do not contain a UDP checksum (i.e.
      the UDP checksum field is zero) are not of significant use over
      wide-areas in the Internet and will not be translated by the
      translator.  An informal trace [MILLER] in the backbone showed that
      out of 34,984,468 IP packets there were 769 fragmented UDP packets
      with a zero checksum.  However, all of them were due to malicious or
      broken behavior; a port scan and first fragments of IP packets that
      are not a multiple of 8 bytes.
   
=> G. Miller message is 10 year old so should be even more valid today.
Thanks for the quote, IMHO the subject can be closed (again).
