OpenVPN

OpenVPN is an open source virtual private network (VPN) program for creating point-to-point or server-to-multi-client encrypted

tunnels between host computers. It can traverse network address translation (NAT) and firewalls and allows authentication by

certificate, pre-shared key or username and password. OpenVPN works well through proxy servers and can run over TCP and

UDP transports. Support for OpenVPN is available on several operating systems, including Windows, Linux, Mac OS, Solaris,

OpenBSD, FreeBSD, NetBSD and QNX.

OpenVPN Server

To configure an OpenVPN Server:

1. Click the OpenVPN profile toggle key to switch it to the ON position.

2. Type a name for the OpenVPN server profile you are creating.

3. Use the Server port field to select a port number and then use the drop down list to select a packet type to use for your

OpenVPN Server. The default OpenVPN port is 1194 and default packet type is UDP.

4. In the VPN network address and VPN network subnet mask fields, enter the IP address and network subnet mask

to assign to your VPN. This is ideally an internal IP address which differs from your existing address scheme.

5. Next to Diffie-Hellman parameters, click the Generate DH button. This will create an encryption key to secure your

OpenVPN connection.

6. Under Server Certificates, enter the required details. All fields must be completed. The Country field must consist of

two characters only. When the details have been entered, click the Generate CA certificate button to generate the

Certificate Authority (CA) certificate based on this information.

7. Under the Server certificates section, select the Authentication type that you would like to use for the OpenVPN

Server.

Note: The Diffie-Hellman parameters can take up to 10 minutes to generate. Please be patient.
