Hi
Have following ipv6 net:2a0a:5400:xxxx:yyyy::/56 ip net. I have subnettet this net into 256 subnets (/64).
The 2 subnets 0 and 2 (2a0a:5400:xxxx:yy00::/64 and 2a0a:5400:xxxx:yy02::/64)  I want to use for WAN/LAN.

My Gateway is at 2a0a:5400:xxxx:yy00::1/64

Is there a link to setup guide on how to setup WAN/LAN with these ip addresses?

Shall I use DHCP or SLAAC or both on LAN?

What about RA and all the possibilities?

Have tryed to look at the online documentation, but I don't find what I want.

Here is a small example (just ignore the HA setup):

https://docs.opnsense.org/manual/how-tos/carp.html#configuring-carp-for-ipv6

Essentially the GUA your ISP routes your prefix to should be configured on the WAN.

For RA use Services - Router Advertisements set to Stateless for the LAN.

You don't need DHCPv6 in most cases.
