Access Control
Access Control, or MAC filtering, is a basic security measure that
should be used on any network that is exposed to a security risk. A
packet filter system examines data packets and scrutinizes them in
order to control network access. Filtering rules determine whether
packets are passed through the Router from either side of the
gateway. The rules are created and controlled by the network
administrator and can be precisely defined. These rules are used to
block access to the LAN from outside the network and/or to deny
access to the WAN from within the network.
MAC Filters
All computers are uniquely identified by their MAC (Media Access
Control) address. The following window will allow users to deny
computers access to the Internet or only allow certain computers
access to the Internet, based on their MAC address. To access this
window, click the Advanced tab along the top of the configuration
window, then the Access Control tab to the left hand side.
To configure MAC filters, manually enter a MAC address to be
filtered by ticking its corresponding checkbox and then configuring
the desired fields on the window above. Select Turn MAC Filtering
OFF, Turn MAC Filtering ON and ALLOW computers listed to access
the network, and Turn MAC Filtering ON and DENY computers listed
to access the network from the drop-down menu. When you are
finished, click the Save Settings button at the top of the window.
