RouterOS PPTP and NAT.

I am attempting to route all my traffic trough an PPTP anonymization service. PPTP is set upp correctly and I get an IP adress that can be pinged from outside.

However I cannot figure out how to configure firewall/nat in order to make my NAT:ed traffic pass trough the PPTP tunnel. The only traffic i want on my physical WAN connection is the PPTP tunnel.

Does anyone has experience in how to achieve this?

Show your config, please.

How do I dump the relevant config in a forum friendly way? I am assuming that WinBOX screenshots its not the optimal option for this.
