AirRouter User Guide
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.
Static
IP Address
This is the IP address to be represented by
the WAN interface which is connected to the external
network. This IP address can be used for the routing and
device management purposes.
Netmask
This is used to define the device IP classification
for the chosen IP address range. 255.255.255.0 is a typical
netmask value for Class C networks, which support
IP address range 192.0.0.x to 223.255.255.x. A Class C
network Netmask uses 24 bits to identify the network
(alternative notation “/24”) and 8 bits to identity the host.
Gateway IP
The IP address of the host router which
resides on the external network and provides the point of
connection to the next hop towards the Internet. This can
be a DSL modem, Cable modem, or a WISP gateway router.
The AirRouter will direct all the packets to the gateway if
the destination host is not within the local network.
Primary DNS IP
Enter the IP address of the Primary DNS
(Domain Name System) server.
Secondary DNS IP
Enter the IP address of the Secondary
DNS (Domain Name System) server. This entry is optional
and only used if the primary DNS server is not responding.
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.
