'rdisc6 eth1' (replace eth1 with WAN interface) may give clues. I suspect that one of:- a) You have older OpenWRT that doesn't deal with DHCPv6 / IPv6 prefix delegation // passthrough automatically without more manua configuration of radvd for prefixes on lan and so on! I highly recommend installing OpenWRT 15.05 (CC) where this all works out-of-the-box often. Lots of IPv6 fixes have now been included. Changelog claims:- "- Improved network auto-setup capable of detecting and bootstrapping IPv4-only, 6rd, Dual-Stack, IPv6-only, DS-Lite, LW4over6, MAP-E, MAP-T, 464XLAT and combinations without explicit configuration [based on RFC 7084]" b) OpenWRT is ONLY getting an RA but never getting a DHCPv6-PD (prefix delegation) to setup a subnet on the secondary side of the router (br-lan). Either they haven't done DHCPv6 that yet or they expect you to use 'bridged mode' (sharing the same /64 on both sides) instead of DHCPv6-PD. > Sebastian --Simon _______________________________________________ openwrt-users mailing list [email protected] https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-users
