well, an application gateway means that you're operating at the
application layer, which means that you are terminating the transport
connections and potentially opening transport connections on a
different transport.
why do that?

So once you limit NAT for IPv6 to a 1:1 mapping (i.e. you no longer
share an address), then it seems like there's isn't a big advantage
over an application gateway.
In fact, I would much prefer an application gateway because you are
no longer interfering with the packets. You are consciously
directing them to a point of policy.
Today, there may not be the perfect way to configure the application
gateway on the hosts but that problem can be easily solved with
either one or more existing DHCP options or some new ones.
This provides the same topology hiding as well as the same multi-
homing capabilities.
What am I missing?
Thanks,
Tom
