245The first variable you'll find is <c>iface_eth0</c>. It uses the following 256The first variable you'll find is called <c>config_eth0</c>. As you can probably
246syntax: 257imagine, this variable configured the eth0 network interface. If the interface
247</p> 258needs to automatically obtain an IP address through DHCP, you should set it
248 259like so:
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> 260</p>
254If you use DHCP (automatic IP retrieval), you should just set <c>iface_eth0</c> 261
255to <c>dhcp</c>. If you use rp-pppoe (e.g. for ADSL), set it to <c>up</c>. 262<pre caption="Automatically obtaining an IP address for eth0">
256If you need to setup your network manually and you're 263config_eth0=( "dhcp" )

268to 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 270
