windows 7\10 LT2P client to mikrotik?

Hello ,
I’m having a problem create a L2TP client from my windows computer to my office router
when using windows 7 I get
error 789 security layer problem


the same thing in windwos 10
I don’t use ipsec just l2tp client

what is wrong?

  • I’m able to connect to the router using another router as l2tp client (so the port is open)
