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.
