Compex Systems 802.11N Manual De Usuario

This section provides more detailed explanation on the network operation modes in general.   

 

The Network Page allows the administrator to setup bridge or routing functionality.   

Device can operate in bridge or router mode. The IP configuration as described below is required 

for device management purposes. IP addresses can either be retrieved from a DHCP server or 

configured manually. Use the Network menu to configure the IP settings.   

 

 Specify the operating network mode for the device.   

 

 

 

        The mode depends on the network topology requirements:   

 

Bridge  operating mode is selected by default as it is widely used by the subscriber stations,       

while connecting to Access Point or using WDS. In this mode the device will act as a    

transparent bridge and will operate in Layer 2. There will be no network segmentation while 

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.   

 

Router operating mode can be configured in order to operate in Layer 3 to perform routing and 

enable network segmentation – wireless clients will be on different IP subnet.   

Router mode will block broadcasts while it is not transparent.   

 

Device supports Multicast packet pass-through in Router mode. Router can act as DHCP server 

and use Network Address Translation (Masquerading) feature which is widely used by the 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.   

 

In bridge mode the device forwards all the network management and data packets from one 

network interface to the other without any intelligent routing. For simple applications this provides 

efficient and fully transparent network solution. WLAN (wireless) and LAN (Ethernet) interfaces 

belong to the same network segment which has 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:
