Users
User Authentication allows an administrator to grant or reject access to specific users from
specific IP addresses, based on their user credentials.
Before any traffic is allowed to pass through any policies configured with username or
groups, the user must first authenticate him/her-self. The DFL-700 can either verify the user
against a local database or passes along the user information to an external authentication
server, which verifies the user and the given password, and transmits the result back to the
firewall. If the authentication is successful, the DFL.700 will remember the source IP address
of this user, and any matching policies with usernames or groups configured will be allowed.
Specific policies that deal with user authentication can be defined, thus leaving policies that
not require user authentication unaffected.
The DFL-700 supports the RADIUS (Remote Authentication Dial In User Service)
authentication protocol. This protocol is heavily used in many scenarios where user
authentication is required, either by itself or as a front-end to other authentication services.
The DFL-700 RADIUS Support
The DFL-700 can use RADIUS to verify users against for example Active Directory or Unix
password-file. It is possible to configure up to two servers, if the first one is down it will try the
second IP instead.
The DFL-700 can use CHAP or PAP when communicating with the RADIUS server.
CHAP
(Challenge Handshake Authentication Protocol) does not allow a remote attacker to
extract the user password from an intercepted RADIUS packet. However, the password must
be stored in plaintext on the RADIUS server.
PAP
(Password Authentication Protocol) might
be defined as the less secure of the two. If a RADIUS packet is intercepted while being
transmitted between the firewall and the RADIUS server, the user password can be extracted,
given time. The upside to this is that the password does not have to be stored in plaintext in
the RADIUS server.
The DFL700 uses a shared secret when connecting to the RADIUS server. The shared
secret enables basic encryption of the user password when the RADIUS-packet is transmitted
from the firewall to the RADIUS server. The shared secret is case sensitive, can contain up to
100 characters, and must be typed exactly the same on both the firewall and the RADIUS
server.

only HTTPS should be used for the login.
Step 3.
Specify the idle-timeout, the time
a user can be idle before being logged out by the firewall.
Step 4.
Choose new ports for the management WebUI to listen on as the user
authentication will use the same ports as the management WebUI is using..
