How to connect VPN via PPTP with Ubuntu

I had tried to connect to my office local network with my Karmic machine via PPTP protocol. I saw a VPN stuff when clicked 'Edit Connections' of NetworkManager Applet (normally on top left of you screen) but couldn't do anything to it. So I started googling and found below.

First, I had to install PPTP for NetworkManager

sudo apt-get install network-manager-pptp

Now, we can do setting PPTP VPN.

Just enter gateway, username and password your PPTP VPN will be now ready to work.

But for me, I want to go out to normal internet with my internet router not to go through my office network. I have to do something a bit.

In editing vpn, click on tab IPv4 setting -> Routes.

Enter ip(s) that want to use vpn and netmark.

You can leave another 2 columns, gateway and metric blank.

Thick in box "Use this connection only for resources on its network"

done.
