This tutorial will explain Howto configure PPTP VPN in Ubuntu Intrepid and Jaunty
Method 1

Preparing your system

First you need to install the following packages

sudo apt-get install pptp-linux ppp pptpd


First you need to edit /etc/ppp/chap-secrets file

sudo gedit /etc/ppp/chap-secrets

add the following line

Username   PPTP   Password   *

Save and exit the file

Create /etc/ppp/peers/vpn1 file using the following command.The ‘peers' folder may be owned by group ‘dip' so get around that by adding yourself to the group .

touch  /etc/ppp/peers/vpn1

sudo gedit /etc/ppp/peers/vpn1

Add the following to the vpn1 file

pty "pptp  --nolaunchpppd"
name Username
remotename PPTP
file /etc/ppp/options.pptp
ipparam vpn1
mru 1412
mtu 1412

Edit the options.pptp file as required. commented out the ‘refuse-chap' and ‘refuse-mschap-v2' lines.

Establish the VPN connection with

sudo pppd call vpn1


sudo pon vpn1

Drop the connection when you're done with

sudo poff vpn1

create ‘/etc/ppp/ip-up.d/route-traffic' as follows.

route add -net ${NET} dev ${IFACE}

Make the file executable using the following command

sudo chmod 755 /etc/ppp/ip-up.d/route-traffic

Replace the "10.0...." address with the range of addresses you need to access on your remote machine.

So, to get the VPN up in Jaunty, Do the following (in /etc/ppp/ip-up.d)

sudo pon vpn1

sudo ./route-traffic

Method 2

Using GUI

From the network manager in the upper right hand corner of your desktop.

Click on "VPN Connections", then "Configure VPN..."

In the Network Connections window, select your VPN Connection and then click the "Edit" button.

In the "Editing Your_VPN PPTP" window, click on the "IPv4 Settings" and then the "Routes..." button.

In the "Editing IPv4 routes...." window, check the box for "Use this connection only for resources on its network".

Now click the "Add" button.I added the Address/Netmask/Gateway information I had to click each box as it seemed to loose the curser position. In my case I work address were in the XXX.YYY.0.0 range so I used a netmask of I set the Gateway to my local router which is (pretty standard). I also used the
value "1" for the Metric. I had to click the "Add" button. This was the only way I could get it to take.

Here was another little tip. While attempting to use this GUI we ended up with several empty routes by accident. The GUI would not let me click on "OK" until we deleted all the empty routes. Just try clicking below your last route. If you are able to make a selection, you have an empty route.

Just click the "Delete" button and you should be good.

Click on "OK", then "Apply", then "Close". Now test your VPN and see if it works any better.

Jaunty Users Tip

-- When you configure the VPN connexion, go to the "advanced" settings"

-- Uncheck "EAP" at the top

-- check the "mppe" parameter

-- Try to connect to your microsoft VPN server,

    The one gotcha with this pptp stuff is that it requires your network iface to be using DHCP.

    This is only for wine and i have not tried with crossover

    Here are some additional notes I neede to get my vpn working:

    1. For Ubuntu 9.10 for the pon to work, copy the
    /etc/ppp/options.pptp to
    /.etc/ppp/options.pptp (not a typo, create a .etc under root)

    2. I was trying to connect to another server once I made my VPN connection. I verified VPN with route. But couldn’t get to my Server.

    I needed
    in /etc/ppp/ip-up.d/route-traffic

    route -add -host dev ppp0

    where xxx is the Server Address.
    then I could telnet to server.

    3. after doing sudo poff vpn1, I noticed the route command still had a connection to vpn.

    route delete -host
    removes line from route
    where is the IP address of the Vpn in the route.

    You should really differentiate between what to do on the server side versus the client side.

    I have set up PPTP VPN server on ubuntu.
    But accounts are open for concurrent simultaneous connections. means there can be many users using one account at the time.
    i need to limit that to one user at the time.
    anybody knows how it can be done?

    It works fine, thanks a lot for the how-to but is it possible to run it on boot? I need the VPN connection being established before a user logs in GDM.
