Network Scenario
1.6 Network Scenario
Figure 1.1 Single AresGate Device Network Scenario
AresGate provides a connection point to the wireless clients and the wired LAN (Figure 1.1). The
WAN port indicates an ADSL interface connection to the DSLAM (Digital Subscriber Line Access
Multiplier) in a central office over an existing phone line. The LAN port indicates an Ethernet interface
connection to a Local Area Network.
Authentication Processing
AresGate authenticates all the clients who are associated with it. Wireless users who wish to pass the
authentication must provide the correct username and password or a valid MAC address stored in a
Remote Authentication Dial-In User Service (RADIUS) server to access the Internet. Wireless users
who failed the authentication process are still permitted to access a pre-configured web page in the
access point for new user registration. Wired users on the LAN network are allowed to access the Inter-
net directly without the authentication process.
Accounting Processing
AresGate sends an accounting message to a RADIUS server periodically during the session, and termi-
nates the user if the session_time limit is reached. The session_time is configurable at the RADIUS
server, and AresGate receives the session_time value when authentication succeeds. User can config-
ure idle_time timers, re-authentication option through RADIUS as well. When the session is termi-
nated, AresGate sends the statistics to the RADIUS server, including session_time, packets, bytes, etc.

Network Scenario

VPI: A virtual path is a semi-permanent connection between endpoints in an ATM
network and may support one or more virtual channels. In Private Virtual
Circuit (PVC) mode, the Virtual Path Identifier (VPI), which is a header
subfield, is assigned manually when ADSL Bridge is used. Different VPI
values allow the endpoints to discriminate between different virtual
connections between ATM nodes.
The minimum and maximum values of the VPI are 0 and 255, respectively. At
default, VPI is set to 0.
VCI: Each connection in an ATM network is characterized by a Virtual Channel
Identifier (VCI). This is a header subfield that is assigned manually when
ADSL Bridge is used. A VCI has only local significance on the link between
ATM nodes. When the connection is released, the VCI value on the involved
links will be released and can be reused by other connections.
The minimum and maximum values of the VCI are 32 and 4095, respectively.
At default, VCI is set to 0.
PPP User Name: The name of the Internet account provided by your ISP.
PPP Password: The password you use to access your ISP account.
OAM F5 Timer: The Operations and Maintenance (OAM) F5 Timer feature transmits
loopback cells to the remote peer according to the specified period. Note that
the local peer will always respond to a loopback cell that is transmitted by the
remote peer. If the OAM F5 timer is set to 0, then no loopback cell will be sent
to the remote peer.

AG2500Series Software User’s Guide June, 2002 13

4.3 Basic - WIRELESS
Figure 4.2 WIRELESS Page
The WIRELESS page provides the configuration parameters for AresGate's wireless feature. It con-
tains the following settings:
SSID (Service Set ID)
The SSID is an unique identifier that AresGate and wireless clients use to associate with each other.
The SSID can be any alphanumeric entry up to 32 characters long and is case sensitive. The default
SSID is AG2500.
Radio Transfer Speed
The radio transfer speed is the data rate that AresGate uses to connect to a wireless client. You can
choose the wireless data transfer rate of the AresGate ranging from 1,2,5.5 to 11Mbps. AresGate will
always attempt the selected speed to link to wireless clients. If a link cannot be established because of
interference or other obstacles, AresGate gears down the speed to the next lowest rate until a link is
successfully established. The default radio transfer speed is 11Mbps.

AG2500Series Software User’s Guide June, 2002 15
Basic - WIRELESS
Wireless Channel Number
Awireless channel number is a specific frequency band at which AresGate communicates with a cli-
ent. You can select one of the 11 channels from the drop-down menu for the AresGate to use. However,
if you enable the Auto-Channeling feature, the channel you selected here will be ignored by the sys-
tem. Instead, it will be replaced by the channel number that the system selected.
Auto-Channeling
When you turn on the Auto-Channeling feature, AresGate automatically scans the surrounding radio
signals, selects the least interference and lowest traffic channel to use, and displays this selected chan-
nel in the above Wireless Channel Number. The default setting of this feature is Off.
NOTE: Turning on the Auto-Channeling feature may cut off the wireless connection between AresGate and
your PC. Click Re-Scan in the Wireless Configuration Utility program installed in your PC to re-estab-
lish the wireless connection.
WEP (Wired Equivalent Privacy)
The Wired Equivalent Privacy (WEP) is used to protect wireless communication from eavesdrop-
ping. Since WEP uses a secret key shared between the communicators, if you enable the WEP feature,
entering the WEP key values below is required.
Default WEP Key
AresGate supports 40-bit and 128-bit WEP keys. For 40-bit WEP encryption, you need to enter 10
hexadecimal digits in one of the key fields below. For 128-bit WEP encryption, you need to enter 26
hexadecimal digits in one of the key fields below. Although there are four key fields you can set up for
AresGate, you can choose only one at a time from the Default WEP Key drop-down menu. The WEP
key is not case-sensitive. The default key field is 1.
1. Enter either 40-bit WEP keys as 10 HEX digits or 128-bit WEP keys as 26 Hex digits
here.
2. Enter either 40-bit WEP keys as 10 HEX digits or 128-bit WEP keys as 26 Hex digits
here.
3. Enter either 40-bit WEP keys as 10 HEX digits or 128-bit WEP keys as 26 Hex digits
here.
4. Enter either 40-bit WEP keys as 10 HEX digits or 128-bit WEP keys as 26 Hex digits

Basic - AUTHENTICATION
16 June, 2002 AG2500Series Software User’s Guide
4.4 Basic - AUTHENTICATION
Figure 4.3 AUTHENTICATION Page
The AUTHENTICATION page allows you to configure AresGate to establish communication with a
RADIUS server for the purpose of user authentication and accounting. If the user passes the authentica-
tion, then the user is allowed access to the network and service that AresGate provides. It performs both
MAC address and EAP (Extensible Authentication Protocol) authentication automatically for all the
associated wireless clients. MAC address authentication is based on user's MAC address of his/her
wireless device for authenticating while EAP authentication is based on the username and password.
