Sent by an access point requesting authentication.
• Access-Reject
Sent by a RADIUS server rejecting access.
• Access-Accept
Sent by a RADIUS server allowing access.
• Access-Challenge
Sent by a RADIUS server requesting more information in order to allow access. The
access point sends a proper response from the user and then sends another Access-Request
message.
The following types of RADIUS messages are exchanged between the ZyWALL and the
RADIUS server for user accounting:
• Accounting-Request
Sent by the access point requesting accounting.
• Accounting-Response
Sent by the RADIUS server to indicate that it has started or stopped accounting.
In order to ensure network security, the ZyWALL and the RADIUS server use a shared secret
key, which is a password, they both know. The key is not sent over the network. In addition to
the shared key, password information exchanged is also encrypted to protect the network from
unauthorized access.
