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.

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.

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.
