It seems your main problem is with dynamic prefix assignment by your ISP. With this alone it is hard todo what you want reliably. There’s 3 options you can opt for:-

1. Bug your ISP to hand you a static prefix. (/56, /60)

2. Use a tunnel broker(HENET)

3. Setup a Wireguard VPN on Linode and route that to your home. You get a fixed /56 from them.

Nothing else I can think of. Good luck.

I think the best way to do this is to setup a Wireguard VPN server on the router itself or on a machine in the LAN. The router firewall will block everything inbound(tcp/udp) except to the inbound VPN udp/IP/port.

Then on the client side you setup a Wireguard client that connects to your Wireguard server remotely and access the LAN resources from there.

Going IPv6-only with what you use the internet for daily will break things.

For time being the recommended approach is a dual-stack setup with NAT64 + DNS64 in the mix.

NAT64 you’ll need Jool on Linux and DNS64 you can just easily use Google or Cloudflare’s public DNS64 servers or run your own.
