One big problem I see from your "ip addr" post is that you only have a link local IP address on your WAN interface (as you have noted).
Here is what I see on my WNR1000v2:

Notice the "2001:558" prefix IPv6 address on the WAN (eth0 for me) interface?
When you tested a standalone PC connected directly to your cable modem, are you sure that you were not seeing a 6to4 tunnel IPv6 connection instead of a native dual stack connection? A 6to4 tunnel would start with a "2002" prefix.
The OpenWRT version that Comcast/Netgear uses on my WNR1000v2 is different than what you are using, so I don't have the same config files (and it appears that Comcast/Netgear is hiding some things even though I have a "root" login). However, here are the .conf files and the dhcp6c-script file that I can see from my telnet interface to that router just in case that information might help you:
