How to use the RPN VPN with your Dedibox Servers

The RPN VPN service allows you to access machines inside your RPN from an external connection or from a Dedibox server that do not have an RPN interface.

The feature is based on OpenVPN and you can add the RPN VPN to your RPNv1 group like any other server.

The RPN VPN service allows you to:

• Connect from anywhere in your totally secure and private network
• Connect servers which do not have an RPN interface to the RPN

How to download the RPN VPN configuration

1. Click Storage > RPN VPN in the top menu of the Dedibox Console. A summary of your RPN VPN services displays.

   

2. Click Configure next to the RPN VPN service you want to configure. The RPN VPN information displays.

   
   Tip:

   If you do not have any RPN VPN services yet, you can click Order RPN VPN directly on the page.

3. Download the certificate files for your RPN VPN. Click Show Password to display the password associated with your RPN VPN.

   
   Note:

   To use your RPN VPN in your RPNv1 group, you must add it to your group as an RPN server. For more information follow our RPN documentation.

How to configure the RPN VPN client

How to configure the Linux client

1. Launch the installation of OpenVPN using the following command.

   root@<your-server-ip>:~# apt install openvpnCopy

2. Edit the client configuration file /etc/openvpn/client.conf in a text editor. For example with nano:

   root@<your-server-ip>:~# nano /etc/openvpn/client.confCopy

   The configuration file looks like the following example:

   client
   dev tun
   ;proto tcp
   proto udp
   float
   remote <IP of the RPN VPN server> 1194
   nobind
   persist-key
   persist-tun
   ca <ca.crt>
   cert <cert.crt>
   key <cert.key>
   askpass <password file>
   ns-cert-type server
   comp-lzo
   verb 3Copy

   Set the following values in the configuration file:

   • <IP of the RPN VPN server>: IP of the RPN VPN server
   • <ca.crt>: Path to ca.crt
   • <cert.crt>: Path to the client .crt
   • <cert.key>: Path to the client .key
   • <password file>: Path to the file containing your password

   Then save the file and exit the text editor.

3. To start the VPN automatically during the boot process of the server, edit the file /etc/default/openvpn and insert the following line:

   AUTOSTART="client"Copy

   This line allows OpenVPN to start automatically with the configuration file located at /etc/openvpn/client.conf.

Once the connection to the RPN VPN server is established, you can use your RPN VPN IP to check whether a new interface displays:

root@mydedibox:/etc/default# ifconfig tun0
tun0      Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  
        inet addr:10.90.250.25  P-t-P:10.90.250.26  Mask:255.255.255.255Copy

You can also check if the routes for the RPN network were set:

root@mydedibox:/etc/default# route -n | grep 10.90
10.90.0.0       10.90.250.26    255.255.0.0     UG    0      0        0 tun0
10.90.250.1     10.90.250.26    255.255.255.255 UGH   0      0        0 tun0
10.90.250.26    0.0.0.0         255.255.255.255 UH    0      0        0 tun0Copy

Now you can configure your server in your RPN group.
