How to make OpenWRT PPTP Client and PPTP Server friends in RouterOS?

Question

Mikrotik

I tried to make friends with the PPTP Server in MikroTik RB2011 with OpenWRT on which I raise the PPTP Client connection.
But unfortunately nothing intelligible happened, the connection comes, but is constantly broken.
Tell me where to dig? Or maybe someone already has a solution to this issue?
What we have on MikroTik:
