Appendix A - Network
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.
Network Mode Selections
Network Mode:
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.
10.1 Bridge Mode
Bridge Mode Network Settings
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:
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:
DHCP :
choose this option to assign the dynamic IP address, Gateway and DNS address by the
local DHCP server.
STATIC :
choose this option to assign the static IP settings for the bridge interface.
IP Address: enter the IP address of the device while Static Bridge IP Address mode is selected.
This IP will be used for the device management purposes.
IP Address and Netmask settings should consist with the address space of the network segment
where device resides. If the device IP settings and administrator PC (which is connected to the
device in wired or wireless way) IP settings will use different address space, the device will become
unreachable.
