The following patches contain an updated version of IPv6 NAT against
Linus' current tree.

Hmmm. Looking in my crystal ball (hi #ipv6!), I predict that if this
lands in mainline - and thus in consumer CPE/routers eventually - many
ISP's will have little incentive to actually implement assigning of
blocks to their consumer users like they "have to" today.

We have this wonderful chance of fixing a major problem with todays
internet, but now we are going down this very slippery slope.

I do need this code for a experimental project myself, and acknowledge
there may be some valid use cases, but I do not like the global
implications one bit.

At least some big fat warnings please?

Clarification: This is about the NAT66 port-based 1:n NAT targets.

We can certainly add a warning to the Kconfig text or (better) the
iptables manpage. But only a very small percentage of people who
might end up (unknowingly) using this will ever see them.

Feel free to send a patch though.
