There's a gotcha for users who have multiple /64 blocks routed to them by AAISP. Current versions of OpenWrt use Policy-Based Routing (PBR) which allows routing to be configured according to multiple rules, not just by destination address. |

If DHCPv6 is used to request Prefix Delegation (PD), AAISP will reply with one block. OpenWrt uses this to set the LAN address and netmask, and then enables routing from '''just this block''' from LAN to WAN. If you have multiple /64 blocks, any other /64 blocks routed to you won't be able to send packets to the Internet. |
