I am going to create a VPN server for my company.
The server is Win2012 and I config it as VPN + NAT. Everything is good when I testing the server.
However, when I try to use my computer to connect to the server through PPTP, Error 806 occur.
My server is a VM machine. As my company has a jumpier, I set the port forward to the server. For the GRE, I choose to use port 2048 to transfer IP protocol GRE.
When I use client to connect the public IP, suppose everything so be alright because I can connect to it by using private IP.
Now, I am not sure where is the problem.
I tried disabling both server's and client's firewall and still occur error 806
