My server uses StrongSwan to host an IPSec server using IKEv1.
Platforms such as Android, iOS, MacOS natively support IPSec connection without using external client application.
Windows 7 and 8 seem to support IPSec IKEv1 very well, but a VPN connection must be established via L2TP tunnel. I would not like to setup L2TP service on the server.
Is there anyway to establish IPSec IKEv1 connection on Windows, without involving L2TP tunnel?
