Brandon,  I also have IPv6 enabled on my AT&T Uverse 2-wire 3800 modem and
cannot initiate an inbound v6 connection.  I do have full outbound  v6
connectivity and rsync my locally hosted website to a cloud machine with
full IPv6 / v4 serving at a much higher bandwidth that I can get from
AT&T.  I too have disabled the 2-wire's firewall but still have found it
locked from the outside.  My 2-wire service is IPv6rd and I do have a /29
static IPv4 that is enabled.  I'll follow your discussion as my experience
is similar to yours and I've fooled around with it for far too long to
justify the cost savings of eliminating the $10 cloud service.

If IP addresses weighed one gram each:
 IPv4 = half the Empire State Building vs.  IPv6 = 56 billion earths

I use Linux and I wouldn't touch Outlook even if I were using a Hazmat suit
and an isolation lab kit.
