How can connect to L2TP/IPSEC VPN Server?

[Faruk KAHRAMAN]

I have a vpn account from a L2TP/IPSEC VPN Server and use four attributes to connect it from Android or Windows devices: IP Adress, User Name, User Password and PreShared Key. I can connect with these details successfully manually. I also want to connect it programmatically in Android 4.x.

I looked into OrbotVPN and ToyVPN projects but couldn't see any details about connecting to existing VPN server. And I think there must be some configuration(server side code) at the remote point (VPN server) to response requests from clients in these projects. But in default; a L2TP/IPSEC VPN server configured already and ready for connections.

Also googled it, all of them says "VpnService is designed for creating custom-protocol VPN applications" but there is no an example of IPSEC implementation.

Is there any example of IPSEC implementation?

Searched my providers page and think this might be useful for you: https://forums.androidcentral.com/e...%2Fvpn-service%2Fipsec-vpn.php&token=t34cPIhQ

And if you're interested, they are also seeking applications for their upcoming BETA program.

Thanks but I am not looking for a VPN service/account. I have already one that use IPSEC protocol. I just want to use it programmatically, establish connection and pass all internet traffic of android device through my VPN server.
