Where NAT disenfranchises the end-user ...

Hello all,

In the recent multi-homing dicussions, many references were made, both
public and private, to encouraging NAT and NAT techniques, in implementing
local multi-homing.

To be honest, even though I've used NAT myself and have implemented NAT for
friends and clients, I would NEVER represent that a NAT'd address has the
full connectivity to the Internet that a static address does. I've had many
people ask me why. I've even gotten some hate-mail from members of this
forum over this. The attached message is one instance-proof of where NAT is
deficient.

If you are selling transit and you are going to NAT them, then you cannot
tell them that they have access to the full internet. There is a *lot* of
stuff that will not transition a NAT boundary. A business that requires
direct Internet access can't use NAT at the border. A business that delivers
services to the internet can't use NAT, for their application servers, at
all.

BTW, I apologize if the subject-line appears inflammatory.
