Astrill Setup Manual:How to configure IPSec Cisco with vpnc client on Linux (Ubuntu)
1. Install vpnc
2. Update vpnc-script
After vpnc is installed you must replace vpnc-script with new version. Ubuntu vpnc package installs old vpnc-script, which results in following error: Error: either "to" is duplicate, or "ipid" is a garbage.

Open terminal and then enter the following commands:
sudo su chmod 777 /etc/vpnc cd /etc/vpnc mv vpnc-script vpnc-script.old wget http://tinyurl.com/vpnc-script chmod 777 vpnc-script
