This guide will not cover how to setup a pptp server as i will talk purely about how to setup a pptp client and to establish connection to a pptp server (which in my case i used mikrotik routerOS as my pptp server which i am not sure if it was based on Poptop, maybe).

Install PPTP client and PPTP Network Manager

sudo apt-get install pptp-linux

sudo apt-get install network-manager-pptp

Setting up the PPTP connection

Once installed, go to System-> Preferences-> Network Connections and follow the steps below.

1. Click on the VPN tab and click Add then select point-to-point tunneling protocol (pptp) in the VPN connection type and click create.

2. Enter the connection name of the VPN entry to create, under General, enter the IP address of the VPN server to connect to.

3. In the Option section, enter your pptp username and password and leave the domain blank if you are not authenticating on a windows domain.

4. Now, click on Advanced and check the Use Point-to-Point encryption (MPPE) box, then click ok.

5. Click on Apply to save settings.

To establish connection to the PPTP server, click on the network icon (my wireless connection icon in my case) and click on VPN connections then click on the connection name you’ve just created. The connection will be dialed immediately and you will see a secure connection icon as soon as you have successfully made a connection to the pptp server.

I took a screenshot on the log facility of my router after i successfully established connection to the pptp server.
