How to connect to the service provider via VPN using SMPP - OpenVPN
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. The
service provider in this example ensures VPN connection via OpenVPN program.
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.
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 OpenVPN program. This OpenVPN server will connect
the remote network and your computer running OpenVPN client.
Please note!!!
To be able to use OpenVPN you need to make sure that you use the same
version number of OpenVPN as the server side (in this example, the service provider)
uses.
Configuration guide
We assume that you have already done the follows:
- You have installed and
configured Ozeki NG SMS Gateway on your PC.
- You have already downloaded OpenVPN with the appropriate version number
- You have already received certificates and keys required for encryption and
authentication; and the configuration file for the connection from your service
provider.
If you have the prerequisites above you can start to configure your VPN connection.
First, you need to install OpenVPN. To do so, start OpenVPN Setup Wizard
(Figure 1).

The OpenVPN Setup Wizard appears. Click on Next (Figure 2).

During installation, Windows will notify you that the driver of
virtual network card (that you will use for connection) has not passed Windows
Logo testing that verifies its compatibility. Please click on Continue Anyway
(Figure 3).

If the connection has been successful then the icon becomes green and
it displays your IP address (Figure 12).

You can check the connection if you ping one of the computer of the
remote network. In this example it will be the SMPP server of the service provider.
If there is a reply it means that connection is successful and it is still
connected (Figure 13).

In Events menu of the created SMPP connection you can check
the connection. If it has been successful it shows: Connection online
(Figure 18).

Specify the message type, the recipient, compose the body of
the message and click on OK (Figure 20).
