D-Link DFL-600 - Manual (Page 40)

User Control This allows you to enable or disable the
authentication of users on the LAN side of the
DFL-600, without changing the configuration
settings. This is useful when you need to
troubleshoot Internet access problems for PCs on
your LAN.
Logout Timer You can enter a maximum amount of time that
users are allowed to be “logged in”. When a
user is logged in for a period of time longer than
that specified here, they must log in again.
Entering a ‘0’ disables the logout timer.
Bandwidth This allows you to enable or disable the
bandwidth control feature of your DFL-600.
Use the drop-down menu to set the maximum
data rate that the DFL-600 will allow between
PCs on your LAN and the WAN (the Internet).
Management Type This allows you to choose and configure the
protocol that the DFL-600 will use to
authenticate users. You can choose between the
LDAP, POP3, RADIUS, Local, or 802.1X
authentication protocols. The Local protocol
means that the DFL-600 itself will provide user
authentication, based on Usernames and
Passwords that are entered by clicking the Add
Users link. You can view the list of users by
clicking the Users List link. The configuration
of the other authentication protocols is described
below.
