Mikrotik in DMZ and PPTP not working

Hello guys.

I have a similar setup that i didn't come out how to fix.

PPtP Client -> Internet -> Dlink dsl router -> Mikrotik

I have a mikrotik router behind a dsl router. In the dsl router i have indicated the ip of the mikrotik as a dmz ip so the mikrotik is shown outside.

In the mikrotik i have configured pptp and the clients can connect but they can not access the other network computers. They can ping only the mikrotik ip (they can also connect and surft the internet).

What may be the problem? Is it related with the dsl router and the dmz confiugration?

May sound a silly question but;

Have you added a route from the PTPP client address space to the LAN address space?

Look like you need to set up proxy-arp on the LAN interface.
