Ipv6 not working

[BladeFireLight]

My isp uses piv6 dhcp-pd to delegate ipv6
My rax50 gets the prefix and does gateway advertisements but is not responding to autoconfig or ipv6 dhcp
Support had me factory reset and I got the same thing

Has anyone gotten ipv6 working on rax50?
Or is there a bug in the firmware

what modem/gateway is the RAX connected to?

Aris surfboard sb8200 I have the prefix deligation from the isp with a /64
The problem is LAN side. It shows a /180 assigned
My devices get the gateway (linklocal of rax50) and dns server (rax Lans side routable ipv6) but not a routable 2600: address

You expect the wan and the lan IPv6 addresses to be different. the wan side is the public ip address the ISP assigns.

what I expect is my PC to be told by the router advertizment what prefix to use and if it's going to use DCHPv6 or SLAC 
but that does not seem to be hapening.
