{{en:tux.png |Hey, my name is "Tux"!}} **Did you ever wonder how you can set up your //Synology// NAS' //OpenVPN// client  to automatic reconnect to a lost //OpenVPN// server connection?**
\\ \\
Hey, my name is "Tux" and this tutorial will show you how you can configure an automatic reconnection of your //Synology// NAS //OpenVPN// client after the connection to its //OpenVPN// server got lost.

----

\\

===== First thoughts =====

<box 97% | Note>
This tutorial assumes that you already have set up a working //OpenVPN// connection between your //Synology// NAS' //OpenVPN// client and the according //OpenVPN// server!
</box>

\\

===== Start of tutorial =====

First of all make sure the //OpenVPN// connection is **disconnected**.
Now open an //SSH// session with your local computer to your //Synology// NAS and prepare the following command (<color #ed1c24>just prepare it but don't execute it yet!</color>):
<cli>$ cat /usr/syno/etc/synovpnclient/vpnc_connecting</cli>

Now establish the //OpenVPN// connection and execute the prepared command simultaneously.

Explanation: During connection establishment the //OpenVPN// client creates temporarly a file called ''/usr/syno/etc/synovpnclient/vpnc_connecting'' and holds it for a few seconds. This file contains an unique connection ID and other informations required for following steps in this tutorial.
\\ The output should look like this:
\\
\\ ''conf_id=<myConnectionID>
\\ conf_name=<myConnectionDescription>
\\ proto=<myVPNType>''
\\
\\ Now change to ''root'' user:
<cli>$ sudo -i</cli>
Create the following script file...
<cli>$ vi /root/connectVPN.sh</cli>
...and add the following content:

<code>
#!/bin/sh
ID=<myConnectionID>
cat >/usr/syno/etc/synovpnclient/vpnc_connecting <<END
conf_id=$ID
conf_name=<myConnectionDescription>
proto=openvpn
END
synovpnc connect --id=$ID
</code>

Save the file and quit the editor.
\\
\\
Now make the script executable:
<cli>$ chmod +x /root/connectVPN.sh</cli>
Now you can set up an according job via //DSM//'s //Task Scheduler// which runs the script on according intervals as you prefer.

\\

===== End of tutorial =====
