Seriously, are we really saying that NAT is great for consumers,
but keep them away from the IETF network because we *know* it won't
work?
it's actually the opposite:
- we *know* that NAT has limited applicability and interferes with
applications that consumers/customers want to deploy
- at the same time most IETF attendees aren't doing things that NATs
would break.
however "most" does not mean "all", and there has traditionally been
some use of the IETF network to test prototypes of new and innovative
applications. imposing NATs on the IETF network would limit the
capability of the network to support such tests.
