LAN IP Address assigned via DHCP with IP fallback

Network - SOHO Router mode
DHCP Fallback IP: In case the external network interface of the Router is
placed in Dynamic IP Address mode (DHCP) and is unable to obtain an IP
address from a valid DHCP server, it will fall back to the static IP address listed
here.
DHCP Fallback Netmask: In case the Router is placed in Dynamic IP Address
mode (DHCP) and unable to obtain an IP address from a valid DHCP server, it
will fall back to the static Netmask listed here.
In case the IP settings of the AirOS powered device are unknown, they can be
retrieved with the help of the [UBNT_Discovery_Utility Ubiquiti Discovery Utility].
Multi-platform Utility should be started on the administrator PC, which resides on
the same network segment as the AirOS device.
AirOS v5.3 system will return to the default IP configuration
(192.168.1.20/255.255.255.0) if the Reset to defaults routine is initiated (more
information in System section).
Auto IP Aliasing configures automatically generated IP Address for the
corresponding WLAN/LAN interface if enabled. Generated IP address is the
unique Class B IP address from the 169.254.X.Y (http://en.wikipedia.org
/wiki/Link-local_address) range (Netmask 255.255.0.0), which are intended for
use within the same network segment only. Auto IP always starts with
169.254.X.Y while X and Y are last 2 digits from device MAC address (i.e. if the
MAC is 00:15:6D:A3:04:FB, Generated unique Auto IP will be 169.254.4.251).
IP Aliases for internal and external network interface can be configured. IP
Aliases can be specified using the IP Aliases configuration window that is opened
while activating the "Configure" button.
IP Address is the alternative IP address for the LAN or WLAN interface,
which can be used for the routing or device management purposes;
Netmask is the network address space identifier for the particular IP Alias;
Comments is the informal field for the comment of the particular IP Alias.
Few words about the alias purpose are saved there usually;
Enabled flag enables or disables the particular IP Alias. All the added IP
Aliases are saved in the system configuration file. However, only the enabled
IP Aliases will be active during the AirOS system operation.
Newly added IP Aliases can be saved by activating Save button or discarded by
activating Cancel button in the Aliases configuration window.
Change MAC Address: When checked, the MAC address of the respective interface may
be changed easily. This is especially useful if your ISP only assigns one valid IP address
associated to a specific MAC address; usually used by Cable operators or some WISP.
SOHO Router
SOHO (= Small Office and Home Office) Router is basically a derivation from
Router mode, which makes the LAN port become the WAN port, and the Wireless
network (WLAN) become the local network.
SOHO router mode only works properly in AP or AP-WDS modes, since it has not
been designed to acts as a wireless client.
In one-Ethernet-port devices (while operating in AP or AP-WDS) this mode
works like the Router mode, except that the LAN port is labeled as “WAN port”
and WLAN as LAN. In two-or-more-Ethernet-ports devices, the main Ethernet
port becomes WAN, and WLAN and other LAN ports become the local network
(LAN).
Note: Don’t use the SOHO Router mode in combination with Station or Station
WDS wireless mode on one-Ethernet-port devices; it may cause the device to
become not accessible. In such a case, reset the device to defaults values by
pressing the Reset button for 8 seconds and then releases it.
WAN Network Settings
'WAN IP Address: This is the IP address to be represented by the WAN interface, which is connected to the external network. This is the
IP address can be used for the routing and the device management purposes.
The WAN interface can be set for static IP or can be set to obtain an IP address from the DHCP server, which should reside in the external
network. One of the IP assignment modes must be selected for the external network interface:
DHCP – choose this option to obtain the IP address, Gateway and DNS address dynamically from the external DHCP server.
PPPoE – choose this option to obtain the IP address, Gateway and DNS address dynamically from the external PPPoE server.
