You need to enable IP forwarding on your PPTP server in order to make you VPN work (This will allow you to forward packets between public IP and private IPs that you setup with PPTP).Enable IP forwarding by using the following command

sudo nano /etc/sysctl.conf

Set`net.ipv4.ip_forward = 1` in the config file. Run the following command to make changes active

sudo sysctl -p

Apply NAT rule for “iptables” using the following commands:

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE && iptables-save
iptables --table nat --append POSTROUTING --out-interface ppp0 -j MASQUERADE
iptables -I INPUT -s 10.0.0.0/8 -i ppp0 -j ACCEPT
iptables --append FORWARD --in-interface eth0 -j ACCEPT

Now all you need is testing your VPN using any PPTP VPN Client.
