It is possible to use VLAN tagging on an interface simply by adding the VLAN IDs
-to it, e.g. \texttt{eth0.1}. These can be nested as well.

This sets up a simple static configuration for \texttt{eth0}. \texttt{proto} specifies the
protocol used for the interface. The default image usually provides \texttt{'none'}
When using the \texttt{'static'} method like in the example, the options \texttt{ipaddr} and
\texttt{netmask} are mandatory, while \texttt{gateway} and \texttt{dns} are optional.
-You can specify more than one DNS server, separated with spaces.
+You can specify more than one DNS server, separated with spaces:

DHCP currently only accepts \texttt{ipaddr} (IP address to request from the server)
and \texttt{hostname} (client hostname identify as) - both are optional.
+\begin{Verbatim}
+config interface "lan"
+ option ifname "eth0"
+ option proto "dhcp"
+ option ipaddr "192.168.1.1" (optional)
+ option hostname "openwrt" (optional)
+\end{Verbatim}

PPP based protocols (\texttt{pppoe}, \texttt{pptp}, ...) accept these options:
\begin{itemize}
\item{username} \\
\end{itemize}
For all protocol types, you can also specify the MTU by using the \texttt{mtu} option.
+A sample PPPoE config would look like this:
+
+\begin{Verbatim}
+config interface "lan"
+ option ifname "eth0"
+ option proto "pppoe"
+ option username "username"
+ option password "openwrt"
+ option mtu 1492 (optional)
