  4. Choose the new expiration time.
  5. Click Continue.

    The certificates have now been renewed. Clients that are not using the new certificates can connect to the OpenVPN server using the old certificates until they expire.

  6. Restart the OpenVPN server to take into use the new certificates.
    1. Click Edit server.
    2. On the next page, click Stop server.
    3. Click the same button, now named Start server, to start the server again.
    CAUTION: All clients are disconnected, and have to connect again when the server is restarted. This causes a brief loss of communication through VPN tunnels.
    Note: The server does not need to be restarted immediately. As long as the old certificates have not expired, the Arctic wireless devices are able to connect to ARM600.
