ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3
Extended Authentication Overview
When many VPN clients connect to a VPN firewall, you might want to use a unique user
authentication method beyond relying on a single common pre-shared key for all clients.
Although you could configure a unique VPN policy for each user, it is more efficient to
authenticate users from a stored list of user accounts. Extended authentication (XAUTH)
provides the mechanism for requesting individual authentication information from the user.
The VPN firewall’s local user database or an external authentication server, such as a
RADIUS server, provides a method for storing the authentication information centrally in the
local network.
You can enable XAUTH when you manually add or change an IKE policy. The VPN firewall
provides two types of XAUTH:
Edge device. The VPN firewall functions as a VPN concentrator on which one or more
gateway tunnels terminate. Specify the authentication type that must be used during
verification of the credentials of the remote VPN gateways: the VPN firewall’s user
database, an external RADIUS-PAP server, or an external RADIUS-CHAP server.
IPSec host. The VPN firewall functions as a VPN client of the remote gateway.
Authentication occurs at the remote gateway through a user name and password that are
associated with the IKE policy. The user name and password that are used to
authenticate the VPN firewall must be specified on the remote gateway.
After you have enabled XAUTH, you must establish user accounts in the VPN firewall’s local
user database to be authenticated against XAUTH or you must enable a RADIUS-CHAP or
RADIUS-PAP server.
If you use a RADIUS-PAP server for authentication, XAUTH first checks the VPN firewall
local user database for the user credentials. If the user account is not present, the VPN
firewall then connects to a RADIUS server.
Enable and Configure Extended Authentication for VPN Clients
The following procedure describes how to enable and configure extended authentication
(XAUTH) for VPN clients.
To enable and configure XAUTH:
1. On your computer, launch an Internet browser.
2. In the address field of your browser, enter the IP address that was assigned to the VPN
firewall during the installation process.
The VPN firewall factory default IP address is 192.168.1.1.
The NETGEAR Configuration Manager Login screen displays.
3. In the Username field, type your user name and in the Password / Passcode field, type
your password.
For the default administrative account, the default user name is admin and the default
password is password.
