<title>Description</title>
<para>
The <command>VBoxManage natnetwork</command> command enables you
to create, modify and manage a NAT network.
</para>
<para>
NAT networks use the Network Address Translation (NAT) service.
The service groups systems into a network and prevents external
systems from directly accessing the systems in the network. The
service also enables the systems in the network to communicate
with each other and with external systems by means of TCP and UDP
over IPv4 and IPv6.
</para>
<para>
A NAT service is attached to an internal network. For a VM to use
the NAT service, you must attach the VM to the internal network.
Specify the name of the internal network when you create the NAT
service. Note that the internal network is created if it does not
already exist.
</para>
<refsect2 id="vboxmanage-natnetwork-add">
<title>Add a NAT Network Service</title>
<remark role="help-copy-synopsis"/>

a new internal network interface, and adds a NAT network

<para>
The following command shows how to create a NAT network for the
<literal>natnet1</literal> internal network that uses the
<literal>192.168.15.0/24</literal> network address and mask of the
NAT service interface. In this static configuration, the gateway
is assigned the <literal>192.168.15.1</literal> IP address by
default. Note that this IP address is the next address after the
network address that you specify with the
<option>--network</option> option.
</para>
<screen>$ VBoxManage natnetwork add --netname natnet1 --network "192.168.15.0/24" --enable</screen>

The following command shows how to add a DHCP server to the
<literal>natnet1</literal> NAT network after creation:
