WPA Mode
: Select the

from the drop-down list.
°
Cipher Type
: Select
TKIP and AES
as the cipher suite. The encryption
algorithm used to secure the data communication.
o
TKIP. Use TKIP only. TKIP (Temporal Key Integrity Protocol) provides
per-packet key generation and is based on WEP.
o
AES. Use AES only. AES (Advanced Encryption Standard) is a very
secure block based encryption. Note that, if the bridge uses the AES
option, the bridge can associate with the access point only if the
access point is also set to use only AES.
o
TKIP and AES. The bridge negotiates the cipher type with the access
point, and uses AES when available.
°
Group Key Update Interval
: Specify the number of seconds before the
group key used for broadcast and multicast data is changed.
°
Pre-Shared Key
: The key is entered as a pass-phrase of up to 63
alphanumeric characters in ASCII (American Standard Code for Information
Interchange) format at both ends of the wireless connection. It cannot be
shorter than eight characters, although for proper security it needs to be of
ample length and should not be a commonly known phrase. This phrase is
used to generate session keys that are unique for each wireless client.

WPA Enterprise (Wi-Fi Protected Access & 802.1x)
Select the WPA-Enterprise radio button if your wireless network uses WPA
encryption. WPA (Wi-Fi Protected Access) was designed to improve upon the
security features of WEP (Wired Equivalent Privacy). The technology is designed
to work with existing Wi-Fi products that have been enabled with WEP. WPA
provides improved data encryption through the Temporal Integrity Protocol
(TKIP), which scrambles the keys using a hashing algorithm and by adding an
integrity checking feature which makes sure that keys haven’t been tampered
with.

This option works with a RADIUS Server to authenticate wireless clients. Wireless
clients should have established the necessary credentials before attempting to
authenticate to the Server through this Gateway. Furthermore, it may be
necessary to configure the RADIUS Server to allow this Gateway to authenticate
users.

: Specify the number of minutes after which the
client will be required to re-authenticate.

RADIUS Server IP Address
: Specify the IP address of the RADIUS server.
°
RADIUS Server Port
: Specify the port number of the RADIUS server, the
default port is 1812.

RADIUS Server Shared Secret
: Specify the pass-phrase that is matched on
the RADIUS Server.

MAC Address Authentication:
Place a check in this box if you would like the
user to always authenticate using the same computer.
°
Optional Backup RADIUS server
: This option enables configuration of an
optional second RADIUS server. A second RADIUS server can be used as
backup for the primary RADIUS server. The second RADIUS server is
consulted only when the primary server is not available or not responding.

WAN
The device offers several types of WAN connections in order to connect to the
Internet.
-
Static IP Address
-
Dynamic IP Address
-
PPPoE
-
PPTP
Select the type of Internet Connection from the drop-down list.
Static IP Address Configuration
The WAN interface can be configured as Static IP address. In this type of
connection, your ISP provides you with a dedicated IP address (which does not
change as DHCP).
Select
Static IP
from the
My Internet Connection
drop-down list.

IP Address:
Specify the IP address for this device, which is assigned by your
ISP.
°
Subnet Mask:
Specify the subnet mask for this IP address, which is assigned
by your ISP.
°
Default Gateway:
Specify the IP address of the default gateway, which is
assigned by your ISP.
°
Primary / Secondary DNS Address:
Specify the primary and secondary IP
address, which is assigned by your ISP.
°
MTU
: The Maximum Transmission Unit (MTU) is a parameter that determines
the largest packet size (in bytes) that the router will send to the WAN. If LAN
devices send larger packets, the router will break them into smaller packets.
Ideally, you should set this to match the MTU of the connection to your ISP.
Typical values are 1500 bytes for an Ethernet connection and 1492 bytes for a
PPPoE connection. If the router's MTU is set too high, packets will be
fragmented downstream. If the router's MTU is set too low, the router will
fragment packets unnecessarily and in extreme cases may be unable to
establish some connections. In either case, network performance can suffer.
°
MAC Address
: If you need to change the MAC address of the router's WAN-
side Ethernet interface, either type in an alternate MAC address (for example,
the MAC address of the router initially connected to the ISP) or click on

Dynamic IP Address (DHCP) Configuration
The WAN interface can be configured as a DHCP Client in which the ISP provides
the IP address to the device. This is also known as Dynamic IP.
Select the
Dynamic IP (DHCP)
from the
My Internet Connection
drop-down
list.
°
Host Name
: Specify a host name to define your system or connection.
°
Use Unicasting
: This option is normally turned off, and should remain off as
long as the WAN-side DHCP server correctly provides an IP address to the
router. However, if the router cannot obtain an IP address from the DHCP
server, the DHCP server may be one that works better with unicast responses.
In this case, turn the Unicasting option on, and observe whether the router
can obtain an IP address. In this mode, the router accepts unicast responses
from the DHCP server instead of broadcast responses.
°
Primary / Secondary DNS Address:
Specify the primary and secondary IP
address, which are assigned by your ISP.
°
MTU
: The Maximum Transmission Unit (MTU) is a parameter that determines
the largest packet size (in bytes) that the router will send to the WAN. If LAN
devices send larger packets, the router will break them into smaller packets.
