I have windows server 2003. I could connect to remote servers overseas using VPN connection. I had no problem yesterday but today when I tried to connect, I kept getting error message:
Disconnected Error 806: a connection between your comuter and the VPN server has been established, but the VPN connection cannot be completed. The most command cause for this is that at least one internet device (for example firewall or router) between your computer and the VPN server is not configured to allow GRE protocal packets. Verify that protocal 47 GRE is allowed on all personal firewall devices or routers.."
No changes has happended to the router configuration and I am not sure why suddenly I can not connect?
Thanks in advance
