Primary Server NAS
Identifier

Note: The VPN firewall functions as an NAS, allowing network access to

xternal users after verification of their authentication information. In a
RADIUS transaction, the NAS needs to provide some NAS identifier
information 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.

s radio button, and then enter the
settings for the three fields to the right. The default setting is that the No radio button is selected.

Secret Phrase A shared secret phrase to authenticate the tra
nsactions between the client
and the backup RADIUS server. The same secret phrase needs to be
configured on both the client and the server.
