Clarifying two comments (maybe I should have proof-read them more carefully)..

Actually, the scenario I described above should not be a problem, as this bullet is about the scope of the _source_ address, not the destination address.. and as the only non-global source address is the link-local, sending back a message should not be a problem.

The this should have been "it is *NOT* appropriate".. .. sorry.. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks. Security. -- George R.R.
