245The first variable you'll find is <c>iface_eth0</c>. It uses the following 241The first variable you'll find is called <c>config_eth0</c>. As you can probably
246syntax: 242imagine, this variable configured the eth0 network interface. If the interface
247</p> 243needs to automatically obtain an IP through DHCP, you should set it like so:
248
249<pre caption="iface_eth0 syntaxis">
250iface_eth0="<i>&lt;your ip address&gt;</i> broadcast <i>&lt;your broadcast address&gt;</i> netmask <i>&lt;your netmask&gt;</i>"
251</pre>
252
253<p> 244</p>
254If you use DHCP (automatic IP retrieval), you should just set <c>iface_eth0</c> 245
255to <c>dhcp</c>. If you use rp-pppoe (e.g. for ADSL), set it to <c>up</c>. 246<pre caption="Automatically obtaining an IP for eth0">
256If you need to setup your network manually and you're 247config_eth0=( "dhcp" )

252to set both <c>config_eth0</c> and <c>routes_eth0</c>:

263So let us give three examples; the first one uses DHCP, the second one a static 254
264IP (192.168.0.2) with netmask 255.255.255.0, broadcast 192.168.0.255 and 255<pre caption="Manually setting IP information for eth0">

290If you have several network interfaces, create extra <c>iface_eth</c> variables,
291like <c>iface_eth1</c>, <c>iface_eth2</c> etc. The <c>gateway</c> variable
292shouldn't be reproduced as you can only set one gateway per computer.
