MacFilters
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 unauthorised people 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.
Create MAC Filter Rules
Enter the Source MAC and Destination MAC details. Entering zeros or blanks into the Source
or Destination fields enters a null value.
'Protocol' provides the choice of protocol type for the rule.
'Mode' provides the choice of Allow or Deny for the rule.
When all selections are made, click on Add to add the rule to the list of rules. A maximum of
20 MAC Filter Rules can be defined and saved.
To save changes, click on Save Settings on the left-hand menu.
