Why is the pptp connection not working on mikrotik?

Question

Mikrotik

I set up a pptp server on Mikrotik with authorization via AD
as in this article
https://habrahabr.ru/sandbox/58551/
in Firewall Rles added rules to the beginning
1 ;;; PPTP
chain=input action=accept protocol=tcp dst-address=
in-interface=ether1 router address dst-port=1723 log=yes log-prefix=""
2 chain=input action=accept protocol=gre dst-address=
in router address -interface=ether1 log=no log-prefix=""

however no connection occurs.
Please tell me where did I go wrong?

Answer 1

Try to remove the address and in-interface

Answer 2

first check the work of pptp within mikrotik, then go further.

Answer 3

Isn't it obvious to you what the problem is? TCP reaches the router, but GRE does not. Info from screenshot. Now solve the question "why GRE does not fly".
