I'm getting the runaround from the chat and phone support, so I don't know where to turn. I am trying to connect to my work VPN, which is a PPTP server. I get the error 806 (says GRE inbound is being blocked) in Windows 7 when connecting from two different machines, and I can connect fine when using another internet connection. I was able to connect fine about a year ago, but haven't been able to at all since I started trying to connect again in the past few weeks.
I did some research on these forums and on dslreports and it looks like the firmware upgrade back in June of 2013 may have caused some issues similar to this one with IPV6. Does anyone have any suggestions for how I can get this to work again? I tried disabling the different methods of threat protection in the 3800HGV options, but nothing has worked. I will have to get rid of uverse and use another provider if I can't get it resolved (which stinks because this is the only issue I've had).
Thanks in advance for all of your help!

Thanks for the help! I didn't have any luck after resetting the gateway to factory defaults. I will try to get a new modem from AT&T support. Thanks again.

What's weird is that I can connect to the VPN server a few times if I renew my IP with the router. But after a few minutes I'm unable to connect again and get the 806 error.
Any thoughts on what it might be?

I have the same problem. How did you fix it?
I've tried dmz mode/firewall disabled and still cant connect through PPTP to our office.VPN works on all other internet providers.
