Config Mode
===========

When in Config Mode a node will neither participate in the mesh nor connect
to the VPN using the WAN port. Instead, it'll offer a web interface on the
LAN port to aid configuration of the node.

Whether a node is in Config Mode can be determined by a characteristic
blinking sequence of the SYS LED:

Activating Config Mode
----------------------

Config Mode is automatically entered at the first boot. You can re-enter
Config Mode by pressing and holding the RESET/WPS/DECT button for about three
seconds. The device should reboot (all LEDs will turn off briefly) and
Config Mode will be available.

If you have access to the console of the node, there is the
``gluon-enter-setup-mode`` command, which reboots a node into Config Mode.


Network-Activated Config Mode
-----------------------------

Some models lack a physical button for activating Config Mode. In this case,
Gluon supports Network-Activated Config Mode. A Linux-utility for activation
can be built by invoking ``make tools``.

To enter Config Mode on a device supporting this method, start the
``enter-network-config-mode`` application in the ``tools`` subdirectory. Start
this tool with the name of the network-interface connected to the target
device as argument. Connect to the LAN-Port (or WAN port if the device has
only a signle interface) and power-cycle the device.

Make sure your computer and the target device are directly connected without
an intermediate switch.

This feature is supported for the following list of devices

* ZyXEL NWA55AXE


Port Configuration
------------------

In general, Config Mode will be offered on the LAN ports. However, there
are two practical exceptions:

* Devices with just one network port will run Config Mode on that port.
* Devices with PoE on the WAN port will run Config Mode on the WAN port instead.


Accessing Config Mode
---------------------

Config Mode can be accessed at http://192.168.1.1. The node will offer DHCP
to clients. Should this fail, you may assign an IP from 192.168.1.0/24 to
your computer manually.
