Hi man，I do follow the steps above, but I have Windows 7 in the VPN dial，ERROR：“error 806: The VPN connection between your computer and the VPN server could not be completed. 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. If the problem persists. contact your network administrator or Internet Service Provider.”

and I add firewall filter

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
/ip firewall filter
add action=accept chain=input disabled=no
add action=accept chain=input disabled=no protocol=tcp src-port=1723
add action=accept chain=input disabled=no protocol=udp src-port=1723
add action=accept chain=input disabled=no protocol=gre
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

OR

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
/ip firewall filter
add action=accept chain=FORWARD disabled=no
add action=accept chain=FORWARD disabled=no protocol=tcp src-port=1723
add action=accept chain=FORWARD disabled=no protocol=udp src-port=1723
add action=accept chain=FORWARD disabled=no protocol=gre
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

You do not do VPN client to VPN client. It has to be VPN client to VPN server.

If we talk about dialing to an external server, you can not have a client on the router AND a client in your LAN doing PPtP to the same server. You have to choose between them. Either the input chain rules with the client on MT, OR forward chain rules with the client in your LAN.

And please don’t post your questions in 2 different sections. This will not bring you anything.
