Thanks for the input guys! Sounds like it might be an issue with my
tunnel then. I had problems getting to a few sites last week
(http://www.dslreports.com/forum/r27265527-IPV6-Issues-Facebook-and-Engadget)
and HE resolved the issue pretty quickly. I will ask them if they are
aware of it.
Thanks,
Derek
