Video: How to connect to the service provider via VPN using SMPP (L2TP IPSec VPN)

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.

If you connect to the remote computers of a remote network you can use your PC 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.

The built-in VPN client of Windows can communicate via L2TP (Level 2 Tunneling Protocol) 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:

  • needs to use L2TP protocol
  • needs to run a VPN server that supports IPSec based encryption
  • the pre shared key (PSK) also needs to be configured on the remote computer
This remote computer can be a computer that runs Windows Server. In this example it is demonstrated how to create an SMPP connection in Ozeki NG SMS Gateway software to connect to the service provider via VPN connection in case the service provider ensures VPN connection via L2TP protocol using IPSec based encryption.
