In computer networking, MAC Filtering (or EUI filtering, or layer 2 address filtering) refers to a security access control methodology whereby the 48-bit address assigned to each network card is used to determine access to the network.
MAC filter can filter each computer through MAC address in LAN; can also bind one MAC address with a static IP address. Following shows a [MAC Filter Config] dialog:
MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists. While the restriction of network access through the use of lists is straightforward, an individual person is not identified by a MAC address, rather a device only, so an authorized person will need to have a whitelist entry for each device that he or she would use to access the network.
While giving a wireless network some additional protection, MAC Filtering can be circumvented by scanning a valid MAC (via airodump-ng) and then changing the own MAC into a validated one. This can be done in the Windows Registry or by using commandline tools on a Linux platform.
[...] What is MAC filtering? [...]
I am trying to set up Mac Filtering on my DSL-2740B. Never managed to make it work.
In Advanced / Wireless Filter, I can add a list of Mac adresses combined to a Wireless Filter Policy.
What ever Policy I use; Disabled; Deny All, Allow All, no filtering occurs.
Does anybody knows how to make it work ?
Thanks
