249The 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
250syntax: 257imagine, this variable configured the eth0 network interface. If the interface
251</p> 258needs to automatically obtain an IP address through DHCP, you should set it
252 259like so:
253<pre caption="iface_eth0 syntaxis">
254iface_eth0="<i>&lt;your ip address&gt;</i> broadcast <i>&lt;your broadcast address&gt;</i> netmask <i>&lt;your netmask&gt;</i>"
255</pre>
256
257<p> 260</p>
258If you use DHCP (automatic IP retrieval), you should just set <c>iface_eth0</c> 261
259to <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">
260If you need to set up your network manually and you're 263config_eth0=( "dhcp" )
261not familiar with all the above terms, please read the section on <uri 264</pre>

265 267However, if you have to enter your own IP address, netmask and gateway, you need
268to set both <c>config_eth0</c> and <c>routes_eth0</c>:
266<p> 269</p>
267So let us give three examples; the first one uses DHCP, the second one a static 270
268IP (192.168.0.2) with netmask 255.255.255.0, broadcast 192.168.0.255 and 271<pre caption="Manually setting IP information for eth0">
269gateway 192.168.0.1 while the third one just activates the interface for 272config_eth0=( "192.168.0.2 netmask 255.255.255.0" )

293<p>
294If you have several network interfaces, create extra <c>iface_eth</c> variables,
295like <c>iface_eth1</c>, <c>iface_eth2</c> etc. The <c>gateway</c> variable
296shouldn't be reproduced as you can only set one gateway per computer.
