If DHCPv6 is used to request Prefix Delegation (PD), AAISP reply with one /64 block. OpenWrt uses this to set the LAN address and netmask, and then enables routing from '''just this block''' from LAN to WAN. Any other /64 blocks routed to you won't be able to send packets to the Internet. In my case, I have 2001:8b0:xxxx:4534::/64, ...:4535/64, ...:4536::/64 and ...:4536::/64 routed to me, but only 4534::~~4534~~ is routed back. # ip -f inet6 route I'm investigating the options: * Configure IPv6 on the WAN manually, not using DHCPv6 * Configure automatically with DHCPv6, ~~adding~~and add the missing ~~routes~~route(s) * See whether delegating a /60 is any better - does DHCPv6 PD reply with the /60 or just one /64 ? = Enabling IPv6 in the local network =
