Source MAC Filtering |
Source MAC Filtering allows you to filter out traffic coming from certain known
machines or devices. The router uses the MAC address of a computer or device on
the network to identify it and block access. Traffic coming in from a specified
MAC address will be blocked while traffic from other MAC addresses will be
allowed through. |
Example: If a computer on the LAN with a MAC
address of 00:01:02:03:04:05, is added to the source MAC filtering list, when
this computer tries to connect to www.yahoo.com (or any other
website), the router will not allow it to connect. However, if this computer is
running some server (e.g., an FTP server), and a firewall rule is defined that
directs all FTP traffic to this machine (if under NAT mode), any machine
on the Internet will be able to make the FTP connection and upload or download
any file successfully. |

Add Source MAC Address to be Blocked: |
To add a MAC Address to the table, input a valid MAC address in the MAC Address field and

a and f inclusive); for example: 00:e0:4c:69:0a:11 |
