ProSafe Dual WAN Gigabit Firewall with SSL & IPsec VPN FVS336Gv2 Reference Manual
To configure RADIUS servers:
1. Select VPN > IPsec VPN from the menu, and then click the RADIUS Client tab.
2. To activate (enable) the primary RADIUS server, click the Yes radio button. The primary
server options become active.
3. Configure the following entries:
Primary RADIUS Server IP address. The IP address of the RADIUS server.
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.
Primary Server NAS Identifier (Network Access Server). This identifier must be
present in a RADIUS request. Ensure that NAS identifier is configured identically 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.
4. Enable a backup RADIUS server (if required).
5. Set the Time Out Period, in seconds, that the VPN firewall should wait for a response
from the RADIUS server.
6. Set the Maximum Retry Count. This is the number of attempts that the VPN firewall will
make to contact the RADIUS server.
7. Click Apply to save the settings.
