PPTP server and LAN

Hello, guys!


I am quite a newbie to RouterOS, but I managed to set up a PPTP server and connect to it using Windows PPTP client.
My clients get Ip adresses from 192.168.1.100-192.168.1.150
And my PC’s address is 192.168.1.3
I can ping from both sides, and access windows shares directly, however they don’t get discovered automatically, I choose Network and it only shows up my local devices, but not the PPTP clients. Would it be possible to make them discover automatically?

Basically I want the clients to be able to discover access all the devices on my LAN and forbid them to get internet access from my WAN.
I have gotten so far that I can access them directly by connecting to specific client’s IP address.

I really hope you can help me and guide me in the right direction.
