Remote PPTP clients can't see network.

RouterOS Beginner Basics

Hello, I’d like to request your help on this problem:
We’ve got an PPTP server up and running, and remote clients can connect to it, but neither they can see network behind it nor they can see each other in explorer.

Something is telling me, that the solution is nearby, but still I can’t figure it out.

If it is routed network then you will not be able to see other PCs in explorer.

If you have set up with proxy-arp then it should work:

It has been set up, still it doesn’t work.
