249DHCP is used by default and does not require any further configuration.

243The first variable you'll find is <c>iface_eth0</c>. It uses the following
244syntax:
245</p> 263<p>
246 264You will see the following file:
247<pre caption="iface_eth0 syntaxis">

249</pre>
250
251<p> 265</p>
252If you use DHCP (automatic IP retrieval), you should just set <c>iface_eth0</c> 266
253to <c>dhcp</c>. If you use rp-pppoe (e.g. for ADSL), set it to <c>up</c>. 267<pre caption="Default /etc/conf.d/net">

261So let us give three examples; the first one uses DHCP, the second one a static
262IP (192.168.0.2) with netmask 255.255.255.0, broadcast 192.168.0.255 and
263gateway 192.168.0.1 while the third one just activates the interface for
264rp-pppoe usage:

287<p>
288If you have several network interfaces, create extra <c>iface_eth</c> variables,
289like <c>iface_eth1</c>, <c>iface_eth2</c> etc. The <c>gateway</c> variable
290shouldn't be reproduced as you can only set one gateway per computer.
291</p>
292
293<!-- New baselayout - current testing
294
295<p>
296The first variable you'll find is called <c>config_eth0</c>. As you can probably
297imagine, this variable configured the eth0 network interface. If the interface
298needs to automatically obtain an IP through DHCP, you should set it like so:
299</p>
300
301<pre caption="Automatically obtaining an IP for eth0">
