How to setup vpn tunnel on dlink620 router?

Question

VPN

Good afternoon.
Tell me, please, how to set up a VPN tunnel on a dlink620 router?
At the moment, there is a microtik router on which the VPN server is up, with this VPN, computers from different networks connect perfectly to Mikrotik, but only if they are created on WIND using standard methods (such as the PPTP VPN protocol)
The router on which you need to raise this VPN connection is connected to the Internet via PPPoE
Ideally, everything should look like this. VPN rises on the router
and all clients connected to the router are already working with our VPN, have access to network drives, shared resources, and so on. But the Internet is organized through their provider
