Good

In the logs below, this is what the No address available means that your 
ISP sent to the ia_na request.
Luckily you have a prefix delegation, so technically you don't need a 
routeable address on your external interface.
You can assing one from the delegation if your ISP supports Prefix 
Exclude - not many do though.

Diagnostic improved here:

Because this is a saved lease, this error must be related to your ia_na.
I'll see if I can log a better diagnostic for this as it's not clear.
But this is why you have no address on your external interface.

Yoiks, that should be a /64

You'll have to tell me why I should be looking at slaacd output and why 
it's relevant to this discussion.
