Trying to set up PureVPN (openVPN) on my Synology Diskstation

Factual Questions
1

It’s asking for a ca.crt but I can’t seem to find or make one.

Can anybody help?

2

You should be able to create a certificate and sign it yourself, or you can use a service like “Let’s encrypt” to sign it for you. What are you trying to do?

Try control panel / security / certificate:

PureVPN certificates are here:

@DPRK is on the right track here. Download the OpenVPN config for Linux, it should have everything in the zip file. I used to have a similar config on my Synology with NordVPN, I have it now implemented on my firewall using policies to force traffic from the Synology exiting to the internet through a tunnel to Nord.

I appreciate y’all, but the OpenVPN for Linux doesn’t contain a ca.crt file

5

I don’t what it was, but changing protocols to PPTP did the trick.

Thanks again

There are certificates if you look at one of those zip archives, e.g. try

Try using OpenVPN instead of PPTP. I heard PPTP is not recommended.

PPTP can be pretty trivial to crack. OpenVPN is much more robust and can be faster.
