The configuration we are trying to achieve here is very basic, as indicated by the figure above. It concerns two RUT routers - RUT1 and RUT2. One functions as a PPTP Server, the other - a PPTP Client. They are connected into a virtual network via a PPTP Tunnel.

If you plan on using the PPTP Server as a web proxy, you will need to edit one preexisting '''Zone Forwarding''' rule. In the router's WebUI, go to '''Network → Firewall → General Settings''', locate '''pptp''' in the Zone Forwarding table and click the "Edit" button next to it:
