How to configure PPTP on DD-WRT firmware flashed Routers

This setup tutorial has been created, tested and is working on ASUS RT-N16 router, flashed with DD-WRT v24-sp2 (08/07/10) mega, (SVN revision 14896).

NOTE: PPTP cannot be used concurrently with PPPoE or Static IP. If your DD-WRT router WAN Connection Type settings are configured with PPPoE or Static IP, you must change Connection Type to Automatic Configuration - DHCP. The WAN port on the DD-WRT router must be directly connected to Ethernet port, or LAN port on a modem (which provides internet connection) for this setup to work properly. Routers must not be on the same subnet, otherwise DHCP will fail to assign IP address to router (you won't be able to connect to router).

MODEM [LAN] port (e.g. ISP modem) <=============> ROUTER [WAN] port (e.g. DD-WRT router)
