1. Installing vpnc

You will first need to get the vpnc package and install it. Fire up a terminal and enter this command:

sudo apt-get install vpnc

2. Creating a *.conf file

cd /etc/vpnc/
cp default.conf mmw.conf

Modify mmw.conf as follows:
(IIIS OpenStack)

#thu.iiis.co 166.111.129.132
#gw.iiis.co  122.200.68.61
IPSec gateway 166.111.129.132    
IPSec ID test
IPSec secret 123456
#IKE Authmode hybrid
Xauth username your_username
Xauth password your_password

3. Using a configuration file

ubuntu@yc-ubuntu:/etc$ sudo vpnc mmw --enable-1des
VPNC started in background (pid: 22892)...
ubuntu@yc-ubuntu:/etc$ ping 10.19.0.80
