* First, set these sysctls:
sysctl -w net.ipv6.conf.$ext_if.forwarding=1
sysctl -w net.ipv6.conf.$int_if.forwarding=1
sysctl -w net.ipv6.conf.$ext_if.proxy_ndp=1
sysctl -w net.ipv6.conf.$int_if.proxy_ndp=1
Make sure to replace '''$ext_if''' with your external interface and '''$int_if''' with your internal interface.

* Also, ensure that you are allowing forwarding with ip6tables. You can either set it up for each interface individually, or just allow all packets:
ip6tables -P FORWARD ACCEPT

* Now, run these on your external interface:
ip link set $ext_if promisc on
ip -6 route add $ext_ip dev $ext_if
ip -6 route add default via $router_ip dev $ext_if metric 512
Replace '''$ext_ip''' and '''$router_ip''' as necessary.

* Next, for each machine you want to add behind your router, run these commands:
ip -6 neigh add proxy $machine_ip dev $ext_if
ip -6 route add $machine_ip dev $int_if
Replace '''$machine_ip''' with the machine's IPv6 address, and replace '''$ext_if''', and '''$int_if''' with the appropriate interfaces as above.

* Finally, run this to allow hosts behind your router to access your router's external IP:
ip -6 neigh add proxy $ext_ip dev $int_if
Replace '''$ext_ip''' and '''$int_if''' as needed.
