Hi!
My scenario:

debian pptp server Mikrotik RB 750 pptp client Client PC
<-----------------------------> <--------------->
pptp tunnel

I want to route all traffic incl. internet from Cient PC over the pptp tunnel.
I have setup the pptp client in Mikrotik with option "Add default Route" .
The tunnel working. I can ping the server tunnel adress from Mikrotik tool.

But when i trace the route for example to google from my client pc, the pptp tunnel is not use.
When I connect the pptp server direct from my client, all traffic is send over tunnel. So the problem must
on Mikrotik Router. I think it is an routing isue.
This is my first Mikrotik router.
