Since Ubuntu 9.0.4 it is very easy to configure Cisco VPN. You don’t need to install the Cisco VPN client. NetworkManager includes support for Cisco IPSec VPNs. NetworkManager attempts to keep an active network connection available at all times. It is intended primarily for laptops where it allows easy switching between local wireless networks, it’s also useful on desktops with a selection of different interfaces to use. It is not intended for usage on servers. This package provides a VPN plugin for vpnc, providing easy access Cisco Concentrator based VPN’s.
First you need to install network-manager-vpnc using the following command:
sudo apt-get install network-manager-vpnc
Now configure your VPN connection:
Click on the NetworkManager icon in the system tray, VPN Connections -> Configure VPN
