@wgarcia I tested it so far on a N5 running RC. Create a config file e.g. vpn.conf
#######################################
IPSec gateway <name-of-vpn-gw>
IPSec ID <ID>
IPSec obfuscated secret <long line of characters make sure it is on 1 line>
Xauth username <your-login>
#######################################
Now call: sudo vpnc-connect --domain <your-domain> /home/phablet/vpn.conf
It will ask first your sudo password, then the password for the VPN service.
At the end this message will be displayed.
VPNC started in background (pid: xxxxxxx)...
Execute command: ifconfig tun0
and you should have a tunnel interface with an IP Address.
To disconnect type: sudo vpnc-disconnect
There is no GUI at the moment, current VPN offers only OpenVPN.
