You can run another router inside, and if the ISP router supports being a
DHCPv6-PD (such as proposed by HIP), you might win.  Otherwise, you might as
well stick with IPv4+NAT, I think (maybe with v6 in a tunnel).

Me, I just buy by own router + modem, and I can't get a modem, many ISPs
understand when you want to turn their router into a modem only.

Right now, with IPv4 only, the ISP provided router (which usually includes
wifi) completely p0wns the house.  I believe that when you get DSL from
free.fr, that they actually put up another ESSID which accepts VoIP traffic
 From their mobile phone subscribers.  That's why free.fr is so inexpensive;
the DSL subscribers provide the mobile phone infrastructure.


Sorry, I was talking about the upstream aggregation router, not the in-home router. That is, if I treat the ISP CPE the same way that I treat my ISP's aggregation router, I can define it as being "outside". That, of course, as you note above means that you
can't use their wireless etc lest you open yourself to be p0wned by them.

As far as DHCPv6 PD, can you just convince their CPE to bridge and let the aggregation router do it, or perhaps just set up their CPE as a DHCP relay, or maybe something else?
As I say I'm not an expert here so sorry if these are dumb questions.

Mike
