Can you show damages in the situation of email? Yes. With packets? No. And
before you come back at me with some crazy convoluted contrived scenario,
let's just realize how far off the beaten path we are at this point. If
your ISP is going to force you to use NAT, "against your will", get a new
fricking provider. For that matter, what ISP NATs you against your will?
Not quite so friend Andy. Someone in UAE claims that I sent
porn to them. And investigation shows that not only is there
a NAT one hop away from the purported victim, there is -another-
NAT in the path, injected by some intermediate ISP as well as
the one injected by my provider. Now I can chage my provider
to one w/o NAT. I can even get the PV to change
their provider (well maybe, given they are in UAE) But how
can we avoid the intermediate ISP that is in the transit path?
And can I persuade the judge that since NATs are known to
muck about w/ addresses & such that I can construct a case
that what was received did not come from me. So the porn
came from one of the NAT operators.
