Connecting to IPSec VPN with Network Manager
Connecting to an IPSec VPN in Ubuntu Linux is easy, but it may take a while until you find your way around Network Manager, which does not bring the vpnc
plugin by default. To install it, simply run:
sudo apt-get install network-manager-vpnc
After that you can add a connection of type Cisco Compatible VPN (vpnc)
and your IPSec VPN will just work.
