243The first variable you'll find is <c>iface_eth0</c>. It uses the following
244syntax:

250
251<p>
252If you use DHCP (automatic IP retrieval), you should just set <c>iface_eth0</c>
253to <c>dhcp</c>. If you use rp-pppoe (e.g. for ADSL), set it to <c>up</c>.
254If you need to set up your network manually and you're
255not familiar with all the above terms, please read the section on <uri

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:

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.
