LAN Network Settings
LAN IP Address This is the IP address to be represented
by the LAN or WLAN interface which is connected to the
external network according to the wireless operation
mode described previously. This IP address can be used for
routing and device management purposes.
The external network 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.
• Static Choose this option to assign the static IP settings
for the external interface.
DHCP
DHCP Fallback IP If the AirRouter is set to 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 If the AirRouter is set to
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.
Enable DMZ The Demilitarized zone (DMZ) can be
enabled and used so that services such as Web Servers,
Proxy Servers, and E-mail Servers can still serve the local
network and are at the same time isolated from it for
additional security. DMZ is commonly used with NAT
functionality as an alternative to Port Forwarding but DMZ
opens all ports of the host network device to the external
network.
•
DMZ Management Port Web Management Port for
the AirRouter (TCP/IP port 80 by default) will be used for
the host device if the DMZ Management Port option is
enabled.
• DMZ IP Enter the IP address of the internal network
device and the device will be completely exposed to the
external network.
Auto IP Aliasing Automatically generates an IP Address
for the corresponding WLAN/LAN interface if enabled.
The generated IP address is a unique Class B IP address
from the 169.254.X.Y range (Netmask 255.255.0.0) which is
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 the MAC address of the device (i.e. if the
MAC is 00:15:6D:A3:04:FB, Generated unique Auto IP will
be 169.254.4.251).
IP Aliases IP aliases for the internal and external network
interface can be configured. IP Aliases can be specified
using the IP Aliases configuration window which is opened
when you click Configure.
• IP The alternative IP address for the LAN or WLAN
interface, which can be used for the routing or device
management purposes.
•
Netmask The network address space identifier for the
particular IP Alias.
• Comments Field used for a brief description of the
purpose of the alias.
• Enabled Enables or disables the particular IP Alias. All
added IP Aliases are saved in the system configuration
file, however only the enabled IP Aliases are active on
the AirRouter.
Newly IP Aliases can be saved by click the Save button
or discarded by clicking the Cancel button in the Aliases
configuration window.
Change MAC Address When enabled, the MAC address
of the respective interface can be changed. This is
especially useful if your ISP only assigns one valid IP
address and it is associated to a specific MAC address;
usually used by Cable operators or some WISPs.
PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) is a
virtual private and secure connection between two
systems which enables encapsulated data transport. It is
commonly used as the medium for subscribers to connect
to Internet Service Providers (typically DSL).
