Also, last time I checked OpenWRT uses dnsmasq to run the DNS forwarder
[which can acually accept requests over either IPv4 and IPv6, in order
to forward them on ....] -- but dns mak is also the DHCPv4 server.
Basically if you disable dnsmasq one way or another this can work.
and enable odhcpd for example? i can live with that if i can figure out how
to build dnsmasq without the dhcp server part which shouldn't be
impossible (don't have much space to spare, 1M max).
Don't bothe -- just turn off dnsmasq entirely. You can point clients
directly to the NAT64 nameserves via RADVD/DHCPv6-stateles [I'd try
without the latter entirely actually...]. Tat way you just don't
need dnsmasq a all.
but to be clear, looking at my settings, especially the 'lan' section in
/etc/config/network, you think that has nothing in it that would trigger
the dns server (dnsmasq in my case) to send out IPv4?
No wll DNSmasq has ALAYS done that that what its' for in part ).. You may
hwever be able to 'disable' DHCPv4 which would be sensibel. I expect
there is a way to do this without recompiling it!!
NB: Search OpenWRT and DNSmasq documentationsa nd wikis -- may be a
simple config option in OpenWRT to just turn off DHCP (DHCPv4).
Setting ip radvd advertising the IPv6 range, similarly, needs attention,
but you sould experiment methodically and look up documatiton properly
and get ther.....
I think, if you use 2001:8b0:6464::1 and 2001:8b0:6464::2 as
DNS resolves, you can use the NAT64 gateway even from a non-AAISP
IPv6 connection, at the moment... see:-
http://aa.net.uk/kb-broadband-ipv6-nat64.html
i thought HE's own dns server would do that. i will have a look at the one
What!?!? Why...
He just provide IPv6 connectivity tunnel for those already with IPv4.
Would make no sense to thn use that to provide IPv4 to me but apparently
thats' what you want .. puzzle!
Be vey intersted to know what you dicover in terms of OSes/software
that do/don't properly support IPv6-only operation.
will report back here.
