Dynamic DNS
Dynamic Domain Name System (DNS) is a mechanism used for translating host
names for network nodes into IP addresses in real-time. This page allows enabling
the Dynamic DNS and selecting the service provider.
The Dynamic DNS page includes the following parameters:
Enable DDNS
- Select this check-box if the unit has a non-static IP address to
keep the domain name associated with an ever-changing IP address.
When DDNS is enabled, configure the following parameters:
»
DDNS User Name
»
DDNS Password
»
DDNS Host Name
DDNS Service Provider
- Select the DDNS service provider from the
drop-down list (Default: www.dyndns.org).

WiFi
Some BreezeMAX Si 4000 models include IEEE 802.11b/g radio interfaces for
local Wi-Fi communications. The Wi-Fi set up pages include configuration options
for the radio signal characteristics and Wi-Fi security.
5.5.1
Wireless Settings
The Wireless Settings page includes the following parameters:
Interface status
- Enables/disables the Wi-Fi radio
Country Code
–The parameter set (list of parameters per country regulations)
by which various parameters are defined (Read-only).
Network Name (SSID)
– The Service Set ID (SSID) that identifies the Wi-Fi
network. The SSID is case sensitive and can consist of up to 32 alphanumeric
characters. (Default: default)
Radio Channel
– The radio channel used by the unit and its clients to
communicate with each other. This channel must be the same on the unit and

all of its wireless clients. The available channel settings are limited by local
regulations. (Default: 1; Range: 1-14, Auto).
Working mode
- The 802.1x authentication is an addition to the WLAN
security methods. It provides a method to protect the network behind the
access point from intruders as well as provide dynamic keys and strengthen
WLAN encryption. (Range: 802.11b, 802.11g, 802.11b/g, Default:802.11b/g)
Transmit Power
– The power of the radio signals transmitted from the unit.
The higher the transmission power, the farther the transmission range. Only
Full power is available.
RTS Threshold
– Sets the packet size threshold at which a Request to Send
(RTS) signal must be sent to a receiving station prior to sending the data
frame. The unit sends RTS frames to a receiving station to negotiate the
sending of a data frame. After receiving an RTS frame, the station sends a CTS
(clear to send) frame to notify the unit that it can start sending data. If a
packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to
Send/Clear to Send) mechanism will be enabled. Units contending for the
medium may not be aware of each other, and the RTS/CTS mechanism can
solve this “Hidden Node Problem.” (Range: 256-2432 bytes: Default: 2432
bytes)
NOTE
If you experience poor performance, you may be encountering interference from another wireless
device. Try changing the channel, as this may eliminate interference and increase performance.

CTS Protect Mode
– When 802.11g and 802.11b clients operate together in
the same Wi-Fi network, there needs to be a mechanism that prevents
802.11b clients from interfering with 802.11g transmissions. This is achieved
by sending 802.11b-compatible CTS (Clear to Send) or RTS/CTS (Request to
Send / Clear to Send) frames before each transmission. This mechanism
decreases the performance of 802.11g clients, but ensures that 802.11b
clients can communicate with the BreezeMAX Si 4000. (Default: Auto)
»
Always off
: If there are no 802.11b clients in the network, the protection
mode can be disabled.
»
Always on
: The transmitting client sends a CTS frame to prevent others
from accessing the medium. This mechanism is effective for most networks
with mixed 802.11g and 802.11b clients.
»
Auto
: Both RTS and CTS frames must be exchanged before a client can
send data. There may be 802.11b clients in some networks that do not
detect the CTS frames from other stations. The full RTS/CTS exchange
should solve most connection problems, but it also has the greatest impact
on network performance.
Preamble Length
– All IEEE 802.11 frames begin with an alternating pattern
of 1s and 0s called the preamble, which tells receiving stations that a frame is
arriving. This provides time for the receiving station to synchronize to the
incoming data stream. This parameter sets the length of the signal preamble
that is used at the start of a data transmission. Using a short preamble
instead of a long preamble can increase data throughput on the unit, but
requires that all clients can support a short preamble. (Default: Short)
»
Short
: Sets the preamble to short (96 microseconds) for increased
throughput.
»
Long
: Sets the preamble to long (192 microseconds. Using a long preamble
ensures the unit can support all 802.11b and 802.11g clients.
SSID Suppress
– The unit is configured by default as an “open system,” which
broadcasts a beacon signal including the configured SSID. Wireless clients
with a configured SSID of “ANY” can read the SSID from the beacon, and
automatically set their SSID for immediate connection to the BreezeMAX Si
4000. When enabled, the unit does not include its SSID in beacon messages.
This provides a basic level of security, since wireless clients must be
configured with the SSID to connect to the BreezeMAX Si 4000.

Wireless Security
The BreezeMAX Si 4000 Wi-Fi interface is configured by default as an “open
system,” which broadcasts a beacon signal including the configured SSID (Service
Set ID). Wireless clients with a configured SSID of “ANY” can read the SSID from
the beacon, and automatically set their SSID to allow immediate connection to the
wireless network.
To implement wireless network security, you have to employ two main functions:
Authentication
– It must be verified that clients attempting to connect to the
network are authorized users. (Default mode is WPA-PSK, see
“WPA/WPA2
Security” on page 62
)
Traffic Encryption
– Data passing between the unit and clients must be
protected from interception and eavesdropping.
For a more secure network, the BreezeMAX Si 4000 can implement one of several
security mechanisms. The security mechanism employed depends on the level of
security required, the network and management resources available, and the
software support provided on wireless clients.
There are eight security options available. When you select the security type from
the list, the required settings are displayed. The option “Open System” together
with encryption disabled is equivalent to no security, all clients will be able to
immediately connect to the Wi-Fi network.
The following sections describe the security options available for the BreezeMAX
Si 4000Wi-Fi network.
5.5.2.1
802.1x
The 802.1x authentication is an addition to the WLAN security methods. It
provides a method to protect the network behind the access point from intruders
as well as provide for dynamic keys and strengthen WLAN encryption.
You can set the following:
Rekey Interval - Interval in seconds between renewals of authentication key
(Default: 3600)
RADIUS Server
RADIUS Port (Default: 1812)
