I can help. Can you send details how to setup the scenario please? Not only do I have access, I also have a long list of co-workers that are are capable and willing.

I'll go back to my notes tomorrow in the ticketing system, and see if I can give more detail. Failing that, I'm going to see if I can recruit someone to help recreate the problem - I don't have Comcast myself.

We implemented MSFT DirectAcess at our company quite some time ago (using 2008R2 and Forefront 2010), and it works extremely well. At least it worked well for everyone until one of the employees got his Comcast connection upgraded, and then DirectAccess didn't work for that employee any more. We proved that if he tethered to his cell phone, that would work, and if he used an SSL VPN client while on his Comcast connect that would work, but DirectAccess would not work at home. Finally, I discovered that his Comcast-installed router was handing our IPv6 addresses on his home LAN. Turning that off enabled DirectAccess to work again. We do not have an assigned IPv6 block from our ISP, though of course MSFT OSes use it, and auto-assign themselves addresses, but for now we're ignoring it. Has anyone run into this problem and solved it - not by turning off iIPv6 address assignment for the home LAN, but really solved it? If so, how did you do that? Would getting and implementing an IPv6 assignment from our ISP cure the problem, or make it worse? I've found little guidance from MSFT about DirectAccess in an IPv6 environment, though I admit I haven't been terribly diligent in my searches. Kurt
