  * Generate ''<name>.ovpn'' file (''<name>'' stands for something meaningful you can decide) from the IPFire web interface and copy it to the computer you want to access the VPN network with.
  * Copy the file and the ''<host>.p12'' file to ''/etc/openvpn'' and rename it to ''<name>.conf''
  * Edit file ''<name>.conf''
    * make sure that the ''remote'' line looks like

     remote emp-lab-gw2 1194

    * and change the line

      pkcs12 <host>.p12
to
      pkcs12 /etc/openvpn/<host>.p12

  * run ''sudo systemctl daemon-reload''
  * the ovpn service can be controlled with
    
    sudo service openvpn@<name> [start|stop|status]
