Pass Through MAC Address List

In addition to permitting specific IP addresses to have “free” network access rights

without authenticating, the DSA-3200 also provides the ability to do so according to a

MAC address. This system permits at most 100 Privileged MAC addresses to have

network access rights without going through user authentication.

The format of the

MAC address is

XX:XX:XX:XX:XX:XX

. These settings will be effective immediately

after you click

“Apply”.

Warning:

Permitting certain MAC addresses to have network access rights without

going through the standard authentication process may pose a security risk.

Note: To allow PCs the ability to access WAN resources through the Public Interface

without authenticating when User Authentication is enabled, specify the IP address for

statically configured PCs or the MAC address for DHCP clients.

IP and MAC

authentication are separate, only one or the other is required to authenticate.
