Note
The RADIUS server is identified by its IP address and UDP port
numbers for the different services it provides. With firmware version
1.0 and greater, the RADIUS server User Datagram Protocol (UDP)
ports used by the access point are configurable. (The AT-WA7400
Wireless Access Point defaults to use RADIUS server UDP port
1812 for authentication and port 1813 for accounting.)
RADIUS IP
The IP address of the RADIUS server.
(The IP address of the AT-WA7400 Wireless Access Point’s internal
authentication server is
127.0.0.1.)
If you have an external RADIUS server on your network, we
recommend using it rather than the using the embedded RADIUS
server on the access point. An external RADIUS server will provide
better security than the local authentication server.
For information on setting up user accounts, see Chapter 4,
“Managing User Accounts” on page 57.
RADIUS Port
The default port number is 1812. You can change this if your
application requires it.
RADIUS Key
The RADIUS Key, the shared secret key for the RADIUS server. The
text you enter will be displayed as “*” characters to prevent others from
seeing the RADIUS key as you type.
(The IP address of the AT-WA7400 Wireless Access Point’s internal
authentication server key is
secret.)
This value is never sent over the network.
WPA Group Rekey Interval
The interval after which the WPA encryption key is automatically
changed and authenticated between devices. The shorter the interval
is, the stronger that the encryption is. Allied Telesyn recommends that
you use the default interval.
Enable RADIUS Accounting
Click Enable RADIUS Accounting if you want to enforce authentication
for WPA client stations with user names and passwords for each
station.
