===== Beispiele mit der Interface Config =====
So wie es sich gehört mit der echten Config unter /etc/network/interfaces
\\

==== Config eines Interfaces ====
<code>
auto eth0
iface eth0 inet static
	address 192.168.100.50
	netmask 255.255.255.0
	network 192.168.100.0
	broadcast 192.168.100.255
	gateway 192.168.100.1
	dns-nameservers 192.168.100.2 192.168.100.3 192.168.100.4
	dns-search mydomain.loc
</code>
\\

==== Config eines Interfaces mit VLAN's ====
<code>
auto eth0
iface eth0 inet manual

auto eth0.100
iface eth0.100 inet manual
	address 192.168.100.50
	netmask 255.255.255.0
