IPv6 via DHCPv6-PD has been working fine for me. I haven't upgraded to the latest CeroWRT, but here is how it works on CeroWRT 3.10.40-5: /etc/config/network: [...] config interface 'se00' option ifname 'se00' option proto 'static' option ipaddr '172.30.42.1' option netmask '255.255.255.224' option ip6assign '64' config interface 'ge00' option ifname 'ge00' option proto 'pppoe' option username 'XXXXXX' option password 'XXXXXX' option _orig_ifname 'ge00' option _orig_bridge 'false' option ipv6 '1' config interface 'wan6' option ifname '@ge00' option proto 'dhcpv6' option broadcast '1' option metric '2048' option reqprefix 'auto' [...] The important parts are the 'ipv6 1', 'reqprefix auto', and ip6assign lines. I only get one /64 from my ISP, so there aren't enough prefixes to assign them automatically to all interfaces, so I removed the ip6assign from everything but se00.
