What does the RA contain? Typically on connection to an IPv6 capable ISP you will get assigned a single /128 from their range and granted a complete routable range at least /64 for you to use.

The interface between the router and the ISP will typically use the router fe80 to connect upstream but it will also have the /128 to use. The router should be able to route the /64 without NAT. If it can't then time for a new router.
