Yes, it is possible to use OpenVPN SSL certificate. IPFire uses OpenVPN which relies on the OpenSSL library for for encryption and authentication including SSL/TLS for key exchange. This allows for secure connection between clients and IPFire OpenVPN Server.
There are different ways how does it works so, you need to understand it in detail:-
