This tutorial guide will walk you through the steps to set up a VPN on your Synology using OpenVPN. For this setup, ExpressVPN highly recommends turning off IPv6.
Find your ExpressVPN account credentials
In order to use ExpressVPN on Synology, you will need to set up a new VPN profile. To set up a VPN profile, you will need your account credentials, and the OpenVPN configuration file. This section of the tutorial will show you how to find all of this information.
Open the Welcome Email you received when you signed up for ExpressVPN. Click the link in the email.
If you can’t find the link, sign in to your account here.
Once you’ve clicked the link in the welcome email or logged into the website, click on Set Up on More Devices.
Click on Manual Config on the left side of the screen and then select the OpenVPN tab on the right. You will first see your username and password and then a list of OpenVPN configuration files.
Download and save the .ovpn file(s) or locations (e.g. Los Angeles, New York, etc.) that you wish to connect to.
Note: Please have your username and password ready, as you will need them later to set up your VPN profile.
Turn off IPv6
Before you enable VPN on your Synology, ExpressVPN highly recommends that you turn off IPv6 to prevent IPv6 traffic from leaking outside of the VPN tunnel.
To turn off IPv6, go to Control Panel > Network > Network Interface.
Click the Network Interface tab, then click the LAN menu to expand it. Click Edit.
In the Edit menu, click the IPv6 tab. For IPv6 setup, select Off. Click OK.
After disabling IPv6, reboot your Synology.
Create a new VPN profile
To add a new VPN profile, we need to return to the Network Interface settings. Go to Control Panel > Network > Network Interface.
Select Create > Create VPN Profile.
Set up your VPN profile
On the VPN Connection Method screen, select OpenVPN (via importing a .ovpn file) and click Next.
On the General Settings screen, enter the following information:
- Profile name: a name to help you remember the connection
- User name: the ExpressVPN username you found above
- Password: the ExpressVPN password you found above
- Import .ovpn file: the OpenVPN configuration file you found above
Check the boxes for Use default gateway on remote network and Reconnect when the VPN connection is lost.
The box for Allow other network devices… is optional.
Click Apply to continue.
Connect to the VPN server
You will now see your new VPN profile in the Network Interface window. Click on your new VPN Profile, then click Connect.
Disconnect from the VPN server
To disconnect from the VPN server, go to Control Panel > Network > Network Interface. Click the VPN profile, then click Disconnect.
