AirRouter User Guide  
Chapter 3: AirOS™  
The AirRouter can act as DHCP server and use Network  
Address Translation (Masquerading) feature which is  
widely used by Access Points. NAT will act as the firewall  
between LAN and WLAN networks. Additional firewall  
settings can be configured for Layer 3 packet filtering  
and access control in Router mode.  
Network  
The Network tab allows the administrator to setup bridge  
or routing functionality. The IP configuration is required  
for device management purposes. IP addresses can either  
be retrieved from a DHCP server or configured manually.  
Use the Network tab to configure the IP settings.  
SOHO Router SOHO (Small Office/Home Office) Router  
is basically a derivation from Router mode. In SOHO  
Router mode, the Main Ethernet port labeled <···>  
functions as the WAN port. The WLAN and LAN ports  
function as the local network (LAN). This is the default  
operating mode of the AirRouter.  
Disable Network This option can be used to disable the  
WLAN, LAN or WAN interface. This setting should be used  
with caution as no L2 or L3 connection can be established  
through the disabled interface. It will be impossible to  
access the AirRouter from the wireless/wired network  
which is connected to the disabled interface. Disable WAN  
is only applicable while operating in SOHO Router mode.  
Bridge  
In Bridge mode, the AirRouter forwards all network  
management and data packets from one network  
interface to the other without any intelligent routing. For  
simple applications this provides an efficient and fully  
transparent network solution. WLAN (wireless) and LAN  
(Ethernet) interfaces belong to the same network segment  
and share the same IP address space. WLAN and LAN  
interfaces form the virtual bridge interface while acting as  
the bridge ports. The bridge has assigned IP settings for  
management purposes.  
Network Role  
The AirRouter can operate in Bridge, Router or SOHO Router  
mode.  
Network Mode Specify the operating network mode  
for the device. There are three modes: Bridge, Router and  
SOHO Router. The default setting for the AirRouter is SOHO  
Router. The mode depends on the network topology  
requirements:  
Network Settings  
Bridge IP Address The device can be set for static IP or  
can be set to obtain an IP address from the DHCP server it  
is connected to. One of the IP assignment modes must be  
selected:  
Bridge In this mode the device will act as a transparent  
bridge and will operate in Layer 2. There will be no  
network segmentation and the broadcast domain will  
be the same. Bridge mode will not block any broadcast  
or multicast traffic. Additional firewall settings can  
be configured for Layer 2 packet filtering and access  
control in Bridge mode.  
DHCP Choose this option to assign the dynamic IP  
address, Gateway and DNS address by the local DHCP  
server.  
- DHCP Fallback IP Enter the IP address for the  
AirRouter to use if a DHCP server is not found.  
Router This operating mode can be configured in order  
to operate in Layer 3 to perform routing and enable  
network segmentation – wireless clients will be on a  
different IP subnet. Router mode will block broadcasts  
while it is not transparent.  
- DHCP Fallback Netmask Enter the netmask for the  
AirRouter to use if a DHCP server is not found.  
The AirRouter supports Multicast packet pass-through  
in Router mode.
