option ip6ifaceid 'eui64'
option ip6assign '64'
The ''list ip6class wan_6'' line causes the lan to use the delegated prefix from wan_6. ''option ip6ifaceid eui64'' makes the local IPv6 address on the lan use the 64 bits derived from the MAC address as the suffix (you might choose to use ''::1'' instead). ''option ip6assign 64'' defines the netmask associated with the prefix delegation.
== Multiple routed IPv6 /64 blocks ==
Then on the ''lan'' interface configure the IPv6 prefix filter to ''wan_6'' and set the IPv6 assignment length to 64. There is a choice of the suffix to append to the prefix - popular choices would be ''::1'' (to use that fixed value), or ''eui64'' (to use an address based on the MAC address).
There is the possibility of running a NAT64 server on OpenWrt, so the local network can use only IPv6 but hosts on it can still reach IPv4 hosts on the Internet.
