=================

The **Network** page contains settings related to the emulated machine's network connectivity.

Network Card #1-#4
------------------

Network interface cards to emulate. Up to 4 independent network cards are supported.

Mode
^^^^

Network emulation mode to use on this card. See :doc:`../hardware/network` for more information on these.

* **Null Driver:** emulate an empty network. All packets are dropped.
* **PCap:** connects directly to a host network adapter. Similar to the **Bridge** mode on other emulators and virtualizers.
* **SLiRP:** creates a private network with a virtual router. Similar to the **NAT** mode on other emulators and virtualizers.
* **VDE:** attaches to a virtual switch created by :ref:`hardware/network:VDE`. Only available on Linux and macOS hosts.
* **TAP:** creates or attaches to a virtual bridge through :ref:`hardware/network:TAP`. Only available on Linux hosts.

.. note::
  If PCap mode is not listed, make sure that:

  * A WinPcap-compatible driver is installed;
  * The installed driver is compatible with your version of Windows;
  * At least one compatible (wired) network adapter is present.

Adapter
^^^^^^^

Network card to emulate. Only cards supported by the machine's expansion buses will be listed.

The *Configure* button opens a new window with settings specific to the selected network card, such as the MAC address for Ethernet cards, and the I/O port and IRQ for ISA cards.

.. note::
  * The MAC address is partially configurable and always prefixed by an `Organizationally Unique Identifier <https://en.wikipedia.org/wiki/Organizationally_unique_identifier>`_ belonging to the card's manufacturer, such as ``00:E0:4C`` for Realtek.
  * The **[LPT] Parallel Port Internet Protocol** network adapter requires a **PLIP Network** device to be attached to a :ref:`parallel port <settings/ports:Parallel port 1-4>`.
  * Settings for the **[COM] Standard Hayes-compliant Modem** are described on :ref:`Networking <hardware/network:Modem>`.

Options
^^^^^^^

Settings for the network emulation mode selected above. Only settings relevant to the selected mode will be shown.

* **Interface:** host network adapter to use in **PCap** mode.
* **VDE Socket:** virtual switch socket path to use in **VDE** mode. See the :ref:`VDE setup guide <hardware/network:VDE>` for more information.
* **TAP Bridge Device:** virtual bridge name to use in **TAP** mode. See :ref:`hardware/network:TAP` for more information.
