UNSUPPORTED OPTIONS
===================

Options listed in this section have been removed from OpenVPN and are no
longer supported

--client-cert-not-required
  Removed in OpenVPN 2.5.  This should be replaxed with
  ``--verify-client-cert none``.

--ifconfig-pool-linear
  Removed in OpenVPN 2.5.  This should be replaced with ``--topology p2p``.

--key-method
  Removed in OpenVPN 2.5.  This option should not be used, as using the old
  ``key-method`` weakens the VPN tunnel security.  The old ``key-method``
  was also only needed when the remote side was older than OpenVPN 2.0.

--no-iv
  Removed in OpenVPN 2.5.  This option should not be used as it weakens the
  VPN tunnel security.  This has been a NOOP option since OpenVPN 2.4.

--no-replay
  Removed in OpenVPN 2.5.  This option should not be used as it weakens the
  VPN tunnel security.

--ns-cert-type
  Removed in OpenVPN 2.5.  The ``nsCertType`` field is no longer supported
  in recent SSL/TLS libraries.  If your certificates does not include *key
  usage* and *extended key usage* fields, they must be upgraded and the
  ``--remote-cert-tls`` option should be used instead.
