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.
