I am running opnsense 24.7.11_2 with dual stack ipv4/6.
My ISP allocates me a IPv6 prefix, and all clients correctly generate a fully routable ipv6 address using SLAAC.
However this prefix can change, and I want to be able to use a stable IPv6 address internally to, for example, connect to DNS or other servers.
I'm unsure what I need to change in opnsense to get the clients to also generate a ULA address. Ideally this would also use SLAAC rather than going down the route of using DHCPv6
Thanks!
Add a Virtual IP to your LAN (or whatever) interface, with a ULA (fdxx:x:x:x::x/64), and configure Router Advertisements for that interface with an appropriate mode (e.g. Unmanaged). Seems to work for me.

Thanks! That was easy once you know what to do.
Working great :-)
