AirRouter User Guide

Static

IP Address and Netmask settings should be consistent 
with the address space of the network segment where 
the AirRouter resides. If the IP of the AirRouter and the IP 
of the administrator PC use a different address space, the 
AirRouter will become unreachable. (Applicable for Static 
mode only)

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. 
(Applicable for Static mode only)

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. (Applicable for Static mode only)
The Gateway IP address should be from the same address 
space (on the same network segment) as the AirRouter’s 
external network interface (Wireless interface in the 
Station or Station WDS mode and the LAN interface in 
Access Point or Access Point WDS mode). (Applicable for 
Static mode only)

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.

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.

SOHO Router

In SOHO (Small Office/Home Office) Router mode, the 
main Ethernet port becomes the WAN port, and the WLAN 
(Wireless LAN) and other LAN ports become the local 
network (LAN).
SOHO router mode only works properly in Access Point or 
Access Point‑WDS mode, since it has not been designed to 
act as a wireless client.
