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.

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
