alt Hacker Newsyou should advertise a local prefix (anything in fd00::/8) in your network and it should just work. no need to use the isp-provided prefix for lan.

For IPv6, multiple addresses on an interface is the norm: an interface has both a public address from your ISP (replacing IPv4 NAT) and a unique local address (replacing stable IPv4 RFC 1918 LAN addresses).
There are some address source selection problems if you're still using any ipv4 for the local services https://blog.ipspace.net/2022/05/ipv6-ula-made-useless/
