OpenVPN® client setup for Synology NAS

Synology NAS is a network-attached storage device with a variety of functions including backing up computer drive and managing and storing media files. 

There are two ways you can cover your Synology NAS with a VPN protection: 

1. Set up VPN connection on your router and connect Synology NAS to this router. If you choose this way, check out the Routers section of our Manuals page for the relevant guides.
2. Configure VPN connection on your Synology NAS. This tutorial provides the step-by-step instruction on how to do it. 
   
   

• Generate and prepare OpenVPN® configuration file
• Set up VPN on Synology NAS
• Turn off IPv6 on your Synology NAS

Generate and prepare OpenVPN® configuration file

Before setting up VPN on Synology NAS, you need to generate the necessary .ovpn file in your KeepSolid User Office. The tutorial How to manually create VPN configurations provides an easy walkthrough to get the required information.

After you generate an .ovpn file, you need to edit it adding port details, otherwise the file won't work on your Synology NAS. Follow the few easy steps below:

1. Open the .ovpn configuration file in a text editor.
2. Scroll down to the </key> tag almost at the end of the document.
3. Under the </key> tag, there is a line containing VPN server domain name, for example de.vpnunlimitedapp.com. Type in 1194 next to the server domain name at the end of this line as shown below.

Set up VPN on Synology NAS 

1. Login to your Synology and open the Control Panel.

2. Go to Connectivity > Network.

3. Navigate to the Network Interface tab and press Create > Create VPN Profile.

4. The Create Profile window with a choice of VPN connection methods will appear. Select the option OpenVPN® (via importing a .ovpn file) and press Next. 

5. Fill out the fields in the following way:
   
   
   • Profile name: Create a name for this connection, for example VPN_Unlimited. 
   • Username: Leave the field blank.
   • Password: Leave the field blank.
   • Import .ovpn file: Upload the .ovpn file you’ve generated in your User Office.
   • CA Certificate: You do not need to upload anything here.
     
     
6. Once completed, press Next.

7. In the Advanced Settings, tick all options and press Next.

8. Select the profile you’ve just created and press Connect. 

9. Wait a few moments till the connection is successfully established. You'll see the profile status change to Connected under the VPN profile.

Turn off IPv6 on your Synology NAS

Before enabling the VPN connection, we recommend you to turn off IPv6 on your Synology NAS. To do this, follow the few simple steps below:

1. Navigate to Control Panel > Network > Network Interface.
2. Click on the LAN menu to expand it.

3. Click Edit.

4. Navigate to the IPv6 tab.

5. In the IPv6 Setup field, select Off and click OK.
