VPN setup on Ubuntu Feisty (7.04) and later

In order to use VPN on Ubuntu Feisty, you need to install support for the VPN protocol:

PPTP (Microsoft VPN)

sudo apt-get install network-manager-pptp

Cisco VPN

sudo apt-get install network-manager-vpnc

OpenVPN

sudo apt-get install network-manager-openvpn

Usage

• Click on the network-manager in the system tray

• Choose VPN Connections -> Configure VPN

• Click Add

• You might have to restart the network-manager to get the added VPN connection on the list (killall nm-applet; nm-applet &)

• Now the VPN connection should be shown in the network-manager

When using Kubuntu Feisty (7.04)

You have to install the additional package

network-manager-gnome

Please refer to WifiDocs/NetworkManager under VPN support for more information.

Commandline

Run the following:

sudo apt-get install pptp-linux

Create file /etc/ppp/peers/YOUR_COMPANY with this content:

pty "pptp YOUR_VPN_GATEWAY --nolaunchpppd"
debug
nodetach
logfd 2
noproxyarp
ipparam YOUR_COMPANY
remotename YOUR_COMPANY
name YOUR_DOMAIN_OR_SERVER_NAME\\YOUR_VPN_LOGIN
require-mppe-128
nobsdcomp
nodeflate
lock
noauth
refuse-eap
refuse-chap
refuse-mschap

Add to /etc/ppp/chap-secrets:

YOUR_DOMAIN_OR_SERVER_NAME\\YOUR_VPN_LOGIN * YOUR_VPN_PASSWORD *

Create file /etc/ppp/ip-up.d/add-subnet with content similar to:

[ "$PPP_IPPARAM" = "YOUR_COMPANY" ] || exit 0
route add -net 192.168.100.0/24 dev $PPP_IFACE

In the above line, adjust subnet values (192.168.100.0/24) if needed

Then run:

sudo chmod a+x /etc/ppp/ip-up.d/add-subnet

- Connect to VPN: sudo pon YOUR_COMPANY To disconnect, press Ctrl+C or close the terminal.

- If you do not want to see VPN connection debug output, in file /etc/ppp/peers/YOUR_COMPANY delete 3 lines: debug nodetach logfd 2

In this case, “pon YOUR_COMPANY” will run as a background process. Use “poff YOUR_COMPANY” to disconnect.
