[Ietf-behave] Fwd: [p2p-hackers] Official IETF behavior recommendations for NATrelevant to P2P

[walter harms]

hi,

there is only one way to combat sloopy/crippeled implementation. inform 
the customer. write a test-programm that checks for all rfc requirements 
and distribute it.
most ppl are not aware what there system should do ( they never read 
specs, exspecialy not rfc's). if a programm say:
"i am sorry to inform you that your network is not conform to rfc xyz.
  reason"
They will feel riped-off. Since most ppl do not understand they will 
stick to the standards (see RFC) and feel uneasy if the do not comply.

educate the masses.
