3. Enable the primary RADIUS server by checking the Yes radio box.
4. Enter the primary RADIUS Server IP address.
5. Enter a Secret Phrase. Transactions between the client and the RADIUS server are
authenticated using a shared secret phrase, so the same Secret Phrase must be configured on
both client and server.
6. Enter the Primary Server NAS Identifier (Network Access Server). This identifier must be
present in a RADIUS request. Ensure that NAS identifier is configured as the same on both
client and server.
The VPN firewall is acting as a NAS (Network Access Server), allowing network access to
external users after verifying their authentication information. In a RADIUS transaction, the
NAS must provide some NAS Identifier information to the RADIUS server. Depending on the
configuration of the RADIUS server, the VPN firewall's IP address may be sufficient as an
identifier, or the Server may require a name, which you would enter here. This name would
also be configured on the RADIUS server, although in some cases it should be left blank on
the RADIUS server.
7. Enable a backup RADIUS server (if required) by following steps 3 through 6.
