MAC Filter Control
MAC filtering enables rules to be defined which allow or deny data to pass through the Router based
on the source and destination MAC address and data type of each data frame.
To access MAC Filters Control, click on Advanced>Advanced Features>MAC Filters .
Usage examples of MAC Filter Rules are: to specify which computers on a network are allowed
Internet access; or to determine which particular computers are allowed to access services provided
by the Router (the last point is particularly relevant for routers serving Wireless Networks as it can be
used to prevent freeloaders from attaching themselves to a wireless LAN).
Enable/Disable MAC Filtering
To enable MAC filtering, navigate to the MAC Filter Control Screen and select the Enable MAC
Filters check box.
If the check box is selected, MAC filtering is enabled according to the list of MAC Filter Rules that
has been created.
If the box is de-selected, MAC Filtering will not be enabled, even if MAC Filter Rules have been
created.
