inaki,

sound ok to me.  if other people don't find any problems with this,
should we write a new version of fix_nated_contact that adds the param
to contact uri or just try to use existing scripting means (remove
contact hf, add a new modified one)?

i haven't checked if it would be possible to do that in the script
(extract and remove received param from r-uri and set $du) or would a
new function need to be written for that too.
