Of course you can! We have a guide explaining how you install and configure OVPN for a Synology NAS.
When OVPN is used on a Synology NAS, it won’t be accessible from outside of your local network since OVPN is using shared IP addresses. If you wish to access your NAS externally, you need to get tour add-on called Public IPv4.
We’ve also compiled a number of articles to help you with troubleshooting and fixing potential issues. You’ll find those guides here.
If you have any troubles getting started with OVPN, we offer free support via TeamViewer. If you should need this, contact us to find a time slot that would work.
