Once configurations done, click on
button to save the configurations and you may create certificates for the OpenVPN clients
now. Each VPN client needs a certificate to be able to connect to the server. OpenVPN server on IPPBX system can connect up to 20
clients.
Each certificate entry created here is for an OpenVPN client. Download the certificate and extract files inside the package, 3 files you’ll
get and they should be uploaded on a client to be able to connect to this server.
