How to set vpn pptp between d-link dfl-860e and d-link dfl-260e?

Question

VPN

Greetings!
Created a PPTP server on the d-link dfl-860e client on the dfl-260e they connected, dfl-260e got an address from the pool that matches the dfl-860e network. The problem is that from the dfl-860e network ping goes to computers behind dfl-260e and from the dfl-260e network ping does not go to computers behind dfl-860e. I understand the matter in routing or incorrect iprules configuration. I can't figure out what's wrong. Help me please!!!
Rules settings on the client

Routes settings on the client

Remote users with windows connect to the server and see the entire network, and with the dfl-260e, the entire network is also visible behind the dfl-860e.
