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 On 7/1/2012 9:35 PM, Frank Bulk wrote:

Someone replied to my DSL Reports thread: http://www.dslreports.com/forum/r27289866- Apparently there is an ACL issue with their load balancer that is blocking ICMP and causing PMTU issues for people who use tunnels. http://www.dslreports.com/forum/r27226136- <http://www.gossamer-threads.com/lists/nsp/ipv6/34197> It looks like it's been going on since June 11. It's strange that Comcast hasn't resolved the issue by now. Thanks, Derek On 7/1/2012 10:20 PM, Jimmy Hess wrote:
