How to connect to the service provider via VPN using SMPP - Built-in VPN Client of Windows (L2TP IPSec VPN)
The example guide below demonstrates how you can create an SMPP
connection in Ozeki NG SMS Gateway to connect to the service provider via VPN. In this
case the VPN connection will be ensured via the built-in VPN client of Windows.
Watch the video tutorial and follow the configuration steps!
VPN refers to Virtual Private Network. VPN enables you to connect
to the remote computers of a remote network via encrypted channel over the
Internet. Since it uses encrypted channel, VPN connection ensures safety.

as if it would be the part of the remote network.
There are various ways to be connected to a remote network via VPN. In this example, you
will find a guide about using the built-in VPN client of Windows.

using IPSec based encryption and PSK (Pre Shared Key).
To be able to connect this client to the remote computer, the remote computer
also needs to meet the following requirements:
The remote computer also:
This remote computer can be a computer that runs Windows Server.
