AirRouter User Guide  
Chapter 3: AirOS™  
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.  
Static Choose this option to assign the static IP settings  
for the bridge interface.  
Note: IP Address and Netmask settings should  
be consistent with the address space of the  
network segment where the AirRouter resides.  
- IP Address Enter the IP address of the device while  
Static Bridge IP Address mode is selected. This IP will  
be used for AirRouter management purposes.  
- Netmask This is a value which when expanded into  
binary provides a mapping to define which portions  
of IP address groups can be classified as host devices  
and network devices. Netmask defines the address  
space of the network segment where the AirRouter  
resides. 255.255.255.0 (or /24) Netmask is commonly  
used on many C Class IP networks.  
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.  
- Gateway IP Typically, this is the IP address of the host  
router which provides the point of connection to the  
Internet. This can be a DSL modem, Cable modem, or  
a WISP gateway router. The AirRouter will direct the  
packets of data to the gateway if the destination host  
is not within the local network.  
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.  
Note: In Bridge mode, the Gateway IP address  
should be from the same address space (on the  
same network segment) as the AirRouter.  
Firewall Settings  
- Primary DNS IP Enter the IP address of the Primary  
Firewall functionality on the bridge interface can be  
enabled by selecting Enable Firewall. Bridge Firewall  
rules can be configured, enabled or disabled while using  
Firewall configuration window which opens when you  
click Configure.  
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.  
Spanning Tree Protocol Multiple interconnected bridges  
create larger networks using the IEEE 802.1d Spanning  
Tree Protocol (STP), which is used for finding the shortest  
path within network and to eliminate loops from the  
topology.  
If enabled, the AirRouter Bridge will communicate with  
other network devices by sending and receiving Bridge  
Protocol Data Units (BPDU). STP should be turned off  
(selected by default) when the AirRouter is the only bridge  
on the LAN or when there are no loops in the topology  
as there is no need for the bridge to participate in the  
Spanning Tree Protocol in this case.  
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  
Ubiquiti Networks, Inc.
