Description
The IP address of the primary RADIUS server.
A shared secret phrase to authenticate the transactions between the client
and the primary RADIUS server. The same secret phrase needs to be
configured on both the client and the server.
The primary Network Access Server (NAS) identifier that needs to be
present in a RADIUS request.
Note: The VPN firewall functions as an NAS, allowing network access to
external users after verification of their authentication information. In a
RADIUS transaction, the NAS needs to provide an NAS identifier to the
RADIUS server. Depending on the configuration of the RADIUS server, the
VPN firewall's IP address might be sufficient as an identifier, or the server
might require a name, which you need to enter in this field.
