Here, with ATT as my upstream, the MODEM, which sits in front of the ROUTER, _serves_ a delegation via DHCP6 via its ROUTER-facing interface. That "IPv6 Addressing Subnet (including length)", apparently configured from upstream, is a /64. THAT is what the ROUTER gets. As far as I tell, that can't be changed. At least not in the UI. Maybe there's a 'hidden' setting you can set via SSH session; I sure haven't found it yet. Internally, the LAN clients get delegated assignments from radvd, using a "prefix ::/64 {" advertisement. I _might_ be able to safely expand that beyond the /64 -- I just am not sure. Since I (1) don't get a /56, and (2) control _none_ of the upstream, sounds like NAT is my best bet. Even if 'ugly'.
