Comment(by robinson):

 atagar,

 I've found that Target can also have a zero port for PURPOSE=DNS_REQUEST.

 {{{
 ProtocolError: Target location's port is invalid: STREAM 1113 NEW 0
 www.google.com:0
  SOURCE_ADDR=127.0.0.1:15297 PURPOSE=DNS_REQUEST
 }}}

 So, it appears safest to allow_zero=True for both source and target.
