Yes - I missed that. Even if I have carefully assigned unique local IPV6 
addresses to all my computers, I suppose the frontend still may try to 
connect to the backend from its global address and not its local 
address. Or, I may not have assigned unique local addresses to my frontends.

So I need to allow incoming IPV6 with subnet that matches any IPV6 
address that I have.
