Its too hard to first build one apps and then its nightmare to make the network work. Is it not possible in Android Mobile/Tablet and all Chrome browsers default to have VPN Client embedded? So that we can do interconnection between:

OpenSWAN server in the cloud with IPSec host to host? Using mobile apps or javascript initialize it for example:

var ipsec = "
conn test
    type=tunnel
    authby=secret
    pfs=no
    # Lifetime: 1440 sec
    ike=aes128-md5;modp1024!
    # Lifetime: 3600 sec
    phase2alg=aes128-md5;modp1024
    aggrmode=no    
    left=xxxx
    leftsubnet=10.109.0.0/24
    right=10.0.0.108
    rightsubnet=10.0.0.0/24
    #auto=start
"
android.vpn.tunnel(ipsec);

EDIT:

How to use the systems VPN from apps or web browsers to make with my VPN server interconnection by using javascript or java code triggering?

• avoid using STUN/UPnP/TURN/ICE/NAT and simply jump to VPN IPSec host to host
