-The network configuration is stored in \texttt{/etc/config/network}
-and is divided into interface configurations.
-Each interface configuration either refers directly to an ethernet/wifi
-interface (\texttt{eth0}, \texttt{wl0}, ..) or to a bridge containing multiple interfaces.
-It looks like this:
-
-\begin{Verbatim}
-config interface "lan"
- option ifname "eth0"
- option proto "static"
- option ipaddr "192.168.1.1"
- option netmask "255.255.255.0"
- option gateway "192.168.1.254"
- option dns "192.168.1.254"
-\end{Verbatim}
-
-\texttt{ifname} specifies the Linux interface name.
-If you want to use bridging on one or more interfaces, set \texttt{ifname} to a list
-of interfaces and add:
-\begin{Verbatim}
- option type "bridge"
-\end{Verbatim}
-
-It is possible to use VLAN tagging on an interface simply by adding the VLAN IDs
-to it, e.g. \texttt{eth0.15}. These can be nested as well. See the switch section for
-this.
-
-\begin{Verbatim}
-config interface
- option ifname "eth0.15"
- option proto "none"
-\end{Verbatim}
-
-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'}
-\texttt{'static'}, \texttt{'dhcp'} and \texttt{'pppoe'}. Others can be added by installing additional
-packages.
-
-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:
-
-\begin{Verbatim}
-config interface "lan"
- option ifname "eth0"
- option proto "static"
- ...
- option dns "192.168.1.254 192.168.1.253" (optional)
-\end{Verbatim}
-
-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} \\
- The PPP username (usually with PAP authentication)
- \item{password} \\
- The PPP password
- \item{keepalive} \\
- Ping the PPP server (using LCP). The value of this option
- specifies the maximum number of failed pings before reconnecting.
- The ping interval defaults to 5, but can be changed by appending
- ",<interval>" to the keepalive value
- \item{demand} \\
- Use Dial on Demand (value specifies the maximum idle time.
- \item{server: (pptp)} \\
- The remote pptp server IP
-\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)
-\end{Verbatim}
-
-\subsubsection{Setting up static routes}
-
-You can set up static routes for a specific interface that will be brought up
-after the interface is configured.
-
-Simply add a config section like this:
-
-\begin{Verbatim}
-config route foo
- option interface "lan"
- option target "1.1.1.0"
- option netmask "255.255.255.0"
- option gateway "192.168.1.1"
-\end{Verbatim}
-
-The name for the route section is optional, the \texttt{interface}, \texttt{target} and
-\texttt{gateway} options are mandatory.
-Leaving out the \texttt{netmask} option will turn the route into a host route.
-
-\subsubsection{Setting up the switch (broadcom only)}
-
-The switch configuration is set by adding a \texttt{'switch'} config section.
-Example:
-
-\begin{Verbatim}
-config switch "eth0"
- option vlan0 "1 2 3 4 5*"
- option vlan1 "0 5"
-\end{Verbatim}
-
-On Broadcom hardware the section name needs to be eth0, as the switch driver
-does not detect the switch on any other physical device.
-Every vlan option needs to have the name vlan<n> where <n> is the VLAN number
-as used in the switch driver.
-As value it takes a list of ports with these optional suffixes:
-
-\begin{itemize}
- \item{\texttt{'*'}:}
- Set the default VLAN (PVID) of the Port to the current VLAN
- \item{\texttt{'u'}:}
- Force the port to be untagged
- \item{\texttt{'t'}:}
- Force the port to be tagged
-\end{itemize}
-
-The CPU port defaults to tagged, all other ports to untagged.
-On Broadcom hardware the CPU port is always 5. The other ports may vary with
-different hardware.
-
-For instance, if you wish to have 3 vlans, like one 3-port switch, 1 port in a
-DMZ, and another one as your WAN interface, use the following configuration :
-
-\begin{Verbatim}
-config switch "eth0"
- option vlan0 "1 2 3 5*"
- option vlan1 "0 5"
- option vlan2 "4 5"
-\end{Verbatim}
-
-Three interfaces will be automatically created using this switch layout :
-\texttt{eth0.0} (vlan0), \texttt{eth0.1} (vlan1) and \texttt{eth0.2} (vlan2).
-You can then assign those interfaces to a custom network configuration name
-like \texttt{lan}, \texttt{wan} or \texttt{dmz} for instance.
-
-\subsubsection{Setting up the switch (swconfig)}
-
-\emph{swconfig} based configurations have a different structure with one extra
-section per vlan. The example below shows a typical configuration:
-
-\begin{Verbatim}
-config 'switch' 'eth0'
- option 'reset' '1'
- option 'enable_vlan' '1'
-
-config 'switch_vlan' 'eth0_1'
- option 'device' 'eth0'
- option 'vlan' '1'
- option 'ports' '0 1 2 3 5t'
-
-config 'switch_vlan' 'eth0_2'
- option 'device' 'eth0'
- option 'vlan' '2'
- option 'ports' '4 5t'
-\end{Verbatim}
-
-\subsubsection{Setting up IPv6 connectivity}
-
-OpenWrt supports IPv6 connectivity using PPP, Tunnel brokers or static
-assignment.
-
-If you use PPP, IPv6 will be setup using IP6CP and there is nothing to
-configure.
-
-To setup an IPv6 tunnel to a tunnel broker, you can install the
-\texttt{6scripts} package and edit the \texttt{/etc/config/6tunnel}
-file and change the settings accordingly :
-
-\begin{Verbatim}
-config 6tunnel
- option tnlifname 'sixbone'
- option remoteip4 '1.0.0.1'
- option localip4 '1.0.0.2'
- option localip6 '2001::DEAD::BEEF::1'
-\end{Verbatim}
-
-\begin{itemize}
- \item{\texttt{'tnlifname'}:}
- Set the interface name of the IPv6 in IPv4 tunnel
- \item{\texttt{'remoteip4'}:}
- IP address of the remote end to establish the 6in4 tunnel.
- This address is given by the tunnel broker
- \item{\texttt{'localip4'}:}
- IP address of your router to establish the 6in4 tunnel.
- It will usually match your WAN IP address.
- \item{\texttt{'localip6'}:}
- IPv6 address to setup on your tunnel side
- This address is given by the tunnel broker
-\end{itemize}
-
-Using the same package you can also setup an IPv6 bridged connection:
-
-\begin{Verbatim}
-config 6bridge
- option bridge 'br6'
-\end{Verbatim}
-
-By default the script bridges the WAN interface with the LAN interface
-and uses ebtables to filter anything that is not IPv6 on the bridge.
-This configuration is particularly useful if your router is not
-IPv6 ND proxy capable (see: http://www.rfc-archive.org/getrfc.php?rfc=4389).
-
-IPv6 static addressing is also supported using a similar setup as
-IPv4 but with the \texttt{ip6} prefixing (when applicable).
-
-\begin{Verbatim}
-config interface "lan"
- option ifname "eth0"
- option proto "static"
- option ip6addr "fe80::200:ff:fe00:0/64"
- option ip6gw "2001::DEAF:BEE:1"
-\end{Verbatim}
