Message-ID: <CAA93jw55X1e90yrXKofRsS9BbN_aVyU==vAuASwgH0sceupA1w@mail.gmail.com> (raw)
I just noticed this thread went over to cerowrt-users and
cerowrt-devel is the right place to discuss these issues.

Subject: Re: [Cerowrt-users] IPv6 router advertisements on custom interfaces
To: cerowrt-users <cerowrt-users@lists.bufferbloat.net>
Fyi I've commited a new ipv6-support version to OpenWrt yesterday.
This includes (partly untested) all features I want to see in there
for OpenWrt except the integration of dnsmasq-dhcpv6 (which will
follow later once the dynamic configuration features have been added
to it) and the WebUI which is still on the ToDo.
So far the current IPv6-featureset is:
* Support for native IPv6 with static configuration
* Support for native IPv6 with DHCPv6-Prefix Delegation
* Support for native IPv6 without PD via relaying or masquerading
* Support for 6in4, 6to4 and 6rd
* Prefixes are automatically split up and distributed over
downstream-interfaces OR by choice mapped to an ULA-address (NPT66).
Help, documentation and configuration examples for yesterdays version
can be found here (there were a few changes for the new NPT-support):
http://wiki.openwrt.org/doc/uci/network6
Especially the NPT / NAT-related stuff has seen very little testing
and of course only works with a Kernel >= 3.7 and ip6tables >= 1.4.17.
