User Guide Example
So I followed the instructions per the User Guide...

220.127.116.11 Setting Up the WAN IPv6 Interface
1) In the Configuration > Network > Interface > Ethernet screen's IPv6 Configuration section, double-click the wan1.
2) The Edit Ethernet screen appears. Select Enable Interface and Enable IPv6.
Click Create new Object to add a DHCPv6 Request object with the Prefix Delegation type.
Select Enable Auto-Configuration
Select Client in the DHCPv6 field. (WAN1's DUID appears.)
Click Add in the DHCPv6 Request Options table and select the DHCPv6 request object you just created. You cannot see the prefix your ISP gave you in the Value field until you click OK and then come back to this screen again. It is 2001:b050:2d::/48 in this example.
Note: Your ISP or a DHCPv6 server in the same network as the WAN should assign an IPv6 address for the WAN interface.
18.104.22.168 Setting Up the LAN Interface
1) In the Configuration > Network > Interface > Ethernet screen, double-click the lan1 in the IPv6 Configuration section.
2) The Edit Ethernet screen appears. Click Show Advanced Settings to display more on this screen.
Select the Enable Interface and Enable IPv6.
In the Address from DHCPv6 Prefix Delegation table, click Add and select the DHCPv6 request object from the drop-down list, type ::1111:0:0:0:1/128 in the Suffix Address field. (The combined address 2001:b050:2d:1111::1/128 will display as LAN1's IPv6 address after you click OK and come back to this screen again).
Note: You can configure the IPv6 Address/Prefix Length field instead if the delegated prefix is never changed.
Select Enable Router Advertisement.
In the Advertised Prefix from DHCPv6 Prefix Delegation table, click Add and select the DHCPv6 request object from the drop-down list, type :1111/64 in the Suffix Address field. (The combined prefix 2001:b050:2d:1111::/64 will display for the LAN1's network prefix after you click OK and come back to this screen again).

The only deviations as you can see in my screenshots are because my IPv6 IP was not the same as their example, obviously. It would seem that I have a /128 (single address) assigned to the WAN and the LAN interfaces, and nothing else.
Curiously, on my Win7 test machine I get from ipconfig /all...
IPv6 Address. . . . . . . . . . . : 2601:d:8a00:17b:1c7d:7f11:7232:f68c(Preferred)
Link-local IPv6 Address . . . . . : fe80::1c7d:7f11:7232:f68c%11(Preferred)
Default Gateway . . . . . . . . . : fe80::ca6c:87ff:fe24:a237%11
(I also get an IPv4 address, which works fine, I just snipped that out for readability)
The result is...
- no IPv6 test site confirms my IPv6 connectivity is working
- my DNS server is on an IPv4 address, and can resolve IPv6 AAAA records resulting in an IPv6 address (so I think that part is OK, or do I also need a DNS server at an actual IPv6 address?
- I though I was supposed to get a /64 block from Comcast starting with 2601: ?
I realize I've exposed my IPv6 and link-local addresses here, and I do so willingly in the name of science - I'll change my MAC and get a different lease later when I'm done playing.
