==== Usage ====

      - Make sure that your internet connection is working (home, during travels,...).
      - Right click on OpenVPN icon in the systray a and click on Connect. Alternatively, if you have setup only one connection a double-click will do the same.
      - To login, use your credentials for the **[[en:navody:eduroam|Eduroam]]** in the form **without "@slu.cz" (for example only xyz9876)**.
      - Icon will turn green after a successful login.
      - Now you are connected to OPFNET and have access to the services normally unavailable outside of the faculty.
