Encouraging all DSL and Cable forum members to have *all* equipment
they produce support BCP 38 filtering at line rate is a good way
to start. This may already be being done. This gets rid of the
"it costs more to buy BCP 38 filtering capable equipment" excuse.
If is doesn't support "BCP 38 filtering" it doesn't get the stamp
Encourage the developement of secure methods to add automatic exceptions
to filters. We have SIDR. Leverage that to say "add a exception for this
block of addresses we have been assigned".
