Hi all,

I have a Mikrotik RB951G-2HND

I followed this link to set up initailly http://wiki.mikrotik.com/wiki/Manual:In ... figuration. I can successfully connect and surf the internet on the router.

I then tried to set up a PPTP VPN connection following this link http://networkingforintegrators.com/2012/08/how-to-vpn/.

When I try to connect using win7 vpn client to the MK router I get Connection Failed with error 778 : it was impossible to verify the identity of the server.

This is what I am getting in the logs: Any help would be appreciated.

Thanks.

I would suggest to check encryption configuration, that is used on PPTP server (on MikroTik) and on your Windows client configuration. Make sure it matches on both ends.

Thanks for the response sergejs but I have tried a number of different variations of pap, chap and mchap2 on both the client and server side. I can see when the packets are being sniffed on wireshark that it gets passed the authentication phase and just drops the connection afterwards. I have attached an image of what I see in wireshark.

What do you have for encryption on /ppp profile or secret?
What configuration do you have for encryption on Windows computer?

Hi sergejs,

Thanks for the replies.

I actually got the VPN to work. I started from scratch and I realized that my test environment was part of my issue.

I have a new issue now: Can't ping any devices on PTPP VPN after connecting to VPN.

I made a post.

Please take a look if you have a minute. Thanks.
