Lets encrypt crt for openvpn server ros7

RouterOS General
1

Good day

I followed the following guide to setup openvpn. It has to openvpn as yealink phones is only that option.
https://blog.nmoleosoftware.com/index.php/2022/06/12/how-to-set-up-and-connect-to-an-openvpn-server-on-mikrotik-routeros-7/

It works as expected. I also setup letsencrypt on router and got cert succesfully.

If someone can help with some guidance on how to use the letsencrypt for the openvpn that will be great. I dont know how to create the client.key or client.crt from the letsencrypt cert or the the selfsigned method sufficient.

Thank you

The technical answer is that you can use a Let’s Encrypt certificate as a client certificate. You cannot, however, use your Let’s Encrypt certificate to sign an additional client certificate which is what you want.
