As a template, we'll be using the sample configuration file that comes along with the OpenVPN installation, but we'll be adding with some minor changes to it. You can find it in the ''OpenVPN'' installation directory, ''sample-config'' folder (default: ''C:\Program Files\OpenVPN\sample-config'') under the name '''''server.ovpn'''''.

    </ul>

</li><li>You can harden (add security) to the VPN by creating a ta.key (''openvpn--genkey --secret keys/ta.key'') file on the server, placing it in the config folder and copying it to the config folder of all client machines.

</li><li>Edit the server.ovpn file found in the OpenVPN/sample-config folder. Lines that begin with # or ; will be ignored.) Feel free to change it however you want.</li></ul>

==Step 5: configuring clients==

==Step 5: configuring clients==

We've already generated certificates and keys for the clients in this guide. The next step is to create a configuration file for the clients. For this purpose we have a separate article: '''[[OpenVPN client on Windows]]'''.

Install OpenVPN on all client machines, but omit Steps 2, 3 and 4 above. Just copy the ca.crt , client.crt and client.key files already created on the server machine in Step 4 above to the config folder of the relevant client machine.  

 

The next step is to create a configuration file for the clients. Edit the client.ovpn file found in the sample-config folder and save it.  Now open the separate article: '''[[OpenVPN client on Windows]],''' but note that only the latter part is relevant to this page. Begin at the line "• Save the file with an '''.ovpn''' extension."

Since you already have the OpenVPN software installed and have generated the certificates and keys for the clients, you can skip to section 4 of that article by clicking '''[[OpenVPN_client_on_Windows#OpenVPN_client_configuration|here]]'''.

Note: The edited client.ovpn file can be copied to all the client machines unless specific changes need to be made.
