I previously was able to create a VPN connection using PPTP.
But as of yesterday, for some unknown reason, I started having intermittent problems. As of today, I can not create my VPN connection. Again, I previously had no problem.
I am working on a Windows Vista Ultimate.
I recently got a new Linksys Router. But this was about a week ago. The problem only started yesterday.
I don't know what to change or how to change things to test this.
I'm getting an 806 error code that appears when I try to VPN. "The VPN connection between your computer and the VPN Server could not be established. The most common cause for this failure is that at least one internet device (for example, a firewall or a router) between your computer and the VPN server is not configured to allow Generic Routing Encapsulation (GRE) protocol packets.
Again, I'm using Windows built in VPN (PPTP) connection. No other application.
Can someone help me identify what the issue is so I can correct it?
PS: It says "Windows did not find any problem with this computer's network connection (when I click on diagnose).
